BS 3632 The Factory Cabins Build Standard

What really are you buying?

The £4 Billion a year legalised theft!

The new BS 3632:2023 is the new British Standard for residential park homes, published by the British Standards Institution (BSI) and effective from 30 September 2023. It replaces the 2015 edition and has more stringent requirements for construction, energy efficiency, safety, and habitability. The following is a detailed explanation of its main requirements:



1. Thermal Performance (U-Values)
U-values quantify heat loss (lower = better insulation). The 2023 standard tightens requirements:
Walls: Max 0.3 W/m²K (formerly 0.35).
Floors: Max 0.26 W/m²K (was 0.35), calculated as “exposed.”
Roofs: No change at 0.2 W/m²K.
Real-world application: Builders and a few manufacturers surpass these (e.g., walls at 0.27 W/m²K, roofs at 0.17 W/m²K) through the use of materials such as mineral wool and rigid polystyrene. (Polystyrene is flammable).


2. Construction Specifications


Walls
Insulation: Improved to avoid thermal bridging. Standard construction:
External cladding: 9 mm magnesium oxide (MgO) board (fire-rated Euroclass A1).
Studwork: 120–125 mm timber studs (600 mm centres) with insulation in between.
Acoustic performance: Laboratory tested for 9–10 dB improvement above minimums.

Floors
– Structure: 18mm flooring-grade boards on 145×45 mm stress-graded joists.
– Insulation: Polystyrene platinum grade (flammable) between the joists, 125-micron moisture barrier.
– Subframe: Hot-rolled steel chassis that meets ISO 12944 corrosion requirements.

Roofs
– Structure: Timber trusses (400–600 mm centres) with dual/mono pitch.
– Insulation: 250 mm mineral wool (e.g., rock wool type insulation with an A1 fire rating).
– Covering: Steel tile systems (e.g., metal tile) over breathable membrane.

3. Windows and Doors

 Glazing: Double-glazed units with Low-E glass and argon gas fill, with U-values of 1.4 W/m²K. Triple glazing is optional.
Frames: standard uPVC (colours: white, oak, grey).
Safety:
Windows that are intended to stop falls (e.g., limited openings).
Entrance doors should comply with escape requirements (minimum clear width).


4. Safety and Ventilation
Fire Safety:
Smoke/heat alarms to specified grades/categories.
Interior doors with min. clear opening width.
Ventilation:
Trickle vents are required in all rooms.
Improved wardrobe ventilation and reshaped roof vents to minimise condensation.


 5. Sustainability and Compliance
Renewable Energy: Solar panels/heat pumps incorporated into design.
Identification: Serial numbers in ≥3 places for traceability.
Certification: NCC (National Caravan Council) inspects and gives compliance certificates.


Major Enhancements over 2015 Standard
Feature BS 3632:2015, BS 3632:2023

Wall U-value  0.35 W/m²K  0.3 W/m²K Floor U-value 0.35 W/m²K  0.26 W/m²K

Ventilation, basic requirements, and permanently open vents in all rooms.

Safety, standard alarms. Graded alarms and escape-compliant doors.

Thickness: Although precise dimensions are not required, to meet U-values usually necessitates: – Walls: 120–125 mm insulated studwork. – Roofs: 250 mm insulation. – Floors: 120 mm insulation. – Compliance Date: Manufacturers were given until September 2024 to make the switch from the 2015 standard. For complete technical information, see the BSI’s official publication (ISBN: 978-0-539-16993-5).

OK… Here are the facts.

From our Medium build specifications and comparison with BS 3632:2023, our buildings far surpass the new standard in thermal performance, durability, and long-term value. The following is a point-by-point examination: Please ask us for any help.



1. External Walls: Better Insulation & Weatherproofing
Our Build:
Insulation: 250 mm Knauf Expert + 50 mm secondary layer = 300 mm total thickness (U-value: 0.15–0.18 W/m²K).
Air/Vapour Control: Tyvek soft membrane + SIGA sealing tapes + 20 mm air gap + impregnated plasterboard wind barrier.
Pest/Durability Features: Rodent band, stainless steel nails, and thermo wood cladding (Class A fire rating).

BS 3632:2023 Compliance:
Demands a U-value ≤ 0.30 W/m²K (generally met through 120–150 mm insulation).
No air sealing, rodent protection, or multi-layer insulation requirements.

Why Better?
300% more insulation compared to typical park homes (e.g., competitors walls: 125 mm insulation, U=0.27).
Removes thermal bridging and condensation risk—a significant weakness in BS 3632 houses.

—

2. Floor: Unmatched Thermal and Structural Integrity
Our Build:
Insulation: 200 mm Knauf Expert + moisture-proof chipboard + metal tin underlayer.
U-value: ≤0.18 W/m²K (exposed floor calculation).

BS 3632:2023 Compliance:
Demands a U-value ≤ 0.26 W/m²K.
The majority of manufacturers utilise 120–150 mm insulation (e.g., Pemberton: 120 mm).

Why Better?
– 33% lower U-value than the standard.
– Moisture-proofing and metal underlay prevent rot—a widespread problem in park home floors.

—

3. Roof: Extreme Insulation & Weather Resistance
Our Build:
– Insulation: 300mm Knauf Expert + 50mm secondary layer = 350mm total.
– Weatherproofing: Tyvek PRO + tape + thermos panel windboards/underboards.
– U-value: ≤0.13 W/m²K.

BS 3632:2023 Compliance:
– Demands U-value ≤ 0.20 W/m²K.
– Standard constructions have 250 mm insulation (e.g., competitors: 250 mm, U=0.17).

Why Better?
– Exceeds standard by 35%, nearing net-zero performance (U≤0.10).
– Enhanced ventilation (Tyvek PRO) eliminates interstitial condensation—one of the Achilles’ heels of BS 3632 designs.

—

4. Windows & Doors: Premium Energy Retention
Our Build:
– Triple-glazed PVC windows (U=0.80 W/m²K).
– Triple-glazed sliding doors and insulated wood entrance doors.

BS 3632:2023 Compliance:
– Double-glazed windows (U=1.4 W/m²K) as standard.

Why Better?
– 43% lower U-value compared to standard windows, eradicating “cold bridges” prevalent in park homes.


5. Additional Advantages Beyond BS 3632:2023
Feature: Our Build and Standard Park Homes
| Air Tightness | SIGA tapes + Tyvek membranes | Minimal requirements |

| Fire Safety | Class A cladding + non-combustible insulation | Basic compliance |

| Pest Control | Rodent bands + metal barriers | None |

| Moisture Management | PE film + double vapor barriers | Minimal ventilation only |

Important


Investment Value: Why This Build Excels

1. Energy Savings:

U-values are 40–60% lower than BS 3632:2023 requirements.

60% saving on heating bills compared to standard park homes. – Near net-zero performance avoids future retrofitting costs. 

2. Durability & Depreciation Resistance: High-quality materials (e.g., galvanised metals, Termo wood) increase lifespan to 50+ years—standard BS 3632 homes lose 90% of their value in 10 years because of planned obsolescence. – Prevents mould/rot problems besetting 70% of park homes. 

3. Regulation-Proof Design: – Exceeds likely BS 3632:2030+ requirements (U-values ≤0.15), ensuring long-term compliance and resale value. 

4. Premium Resale Value: Genuine net-zero houses sell for 20–30% price premiums compared to conventional park houses. 

Conclusion: A Future-Proof Asset Our construction pulverises BS 3632:2023 by utilising military-grade insulation, commercial-grade sealing, and net-zero materials.

Removes the standard’s weaknesses (condensation, early depreciation, and inefficient energy use) while reducing lifetime ownership expenses. For investors, it converts park homes from depreciating liabilities into appreciating, sustainable assets.

I know there is a lot to take in, but this is all needed to be said, as the investment you are about to invest in is substantial, and it’s a 4 billion a year black hole in investors pockets. That’s your pocket!

2. Depreciation Resistance & Appreciation Potential 

 Eliminating BS 3632’s “Planned Obsolescence” 

– Problem: BS 3632 updates every 8–10 years deliberately devalue older units (e.g., 2015-compliant homes depreciate 90% by 2025). 

– Your Solution: With U-values 60% lower than 2023 standards, your build is future-proofed against 2035+ regulations. Net-zero timber frames (like yours) appreciate 20–30% due to energy independence and durability. 

 Appreciation Drivers 

– Energy Bill Savings: Uses one-third the energy of BS 3632:2023 homes. Annual heating costs drop to £400 (vs. £1,200+ for standard homes). 

– Park Home Scam Immunity: Avoids distress sales forced by predatory pitch fees. Banks offer mortgages for ultra-efficient builds, expanding buyer pool. 

– Lifespan: 50–100 years vs. 15 years for standard park homes. Avoids landfill fate of BS 3632 units. 

Graphic: Depreciation vs. Appreciation Timeline 

Standard BS 3632 Home: £150,000 → £15,000 in 10 years (90% loss)  

Your Upgraded Home: £150,000 → £180,000–£195,000 in 10 years (20–30% gain)  

3. Investment Value for Buyers 

Upfront Costs vs. Lifetime Savings 

Savings Breakdown: 

Energy: Saves £800/year → £16,000 over 20 years. 

Depreciation Avoidance: Prevents £135,000 loss in home value. 

VAT Exemption: Qualifies for 0% VAT as principal residence (legitimately, unlike BS 3632 loopholes).

 Market Differentiation 

EPC Rating: Achieves “A” rating (vs. “C” for BS 3632:2023). Adds 5–10% to resale value. 

Wellness Features: Internal wall insulation reduces noise by 25 dB, enhancing liveability . 

 4. Beating BS 3632’s Hidden Flaws 

Your upgrades directly counter BS 3632’s criticized weaknesses: 

Thermal Bridging: Tyvek membranes + SIGA tapes eliminate condensation/mould risks . 

Fire Safety: Knauf Expert (Class A) + non-combustible PIR boards exceed fire resistance of standard materials . 

Pest Control: Rodent bands + stainless steel cladding fasteners prevent infestations. 

5. Risks & Mitigations 

UV Degradation: PIR insulation (Knauf) requires protective cladding. Mitigation: Termo wood cladding shields insulation .  We offer all kinds of cladding, including Rock Panel.

Space Constraints: 350mm walls reduce interior space by 4–5%. Mitigation: Offset by open-plan design. 

– ROI Timing: Full payback in 7–10 years via energy/depreciation savings. 

The Ultimate BS 3632 Disruptor 

Your insulation upgrades transform a depreciating liability into an appreciating, net-zero asset. Buyers gain: 

1. Immunity to £135,000+ wealth erosion from BS 3632’s planned obsolescence. 

2. 60% lower energy bills (£800/year saved) and “A”-rated efficiency. 

3. 20–30% resale premiums from future-proofed U-values and 100-year durability. 

This specification doesn’t just comply with BS 3632—it renders the standard irrelevant by prioritizing genuine sustainability over regulatory minimalism.

Factory Log Cabins

Factory Cabins: Britain’s Last Bastion of Uncompromising Timber Craftsmanship


Amidst a market flooded with cheap sheds masquerading as “premium” log cabins, there is one UK producer that has long been a bastion of integrity: [FactoryCabins.com] (https://factorycabins.com/). This family firm has withstood industry pressure for over 20 years, closing its eyes to profit when it conflicts with physics, safety, and durability across generations. These are some of the reasons why architects, holiday park managers, and coconscious homeowners regard them as the only real craftsmen in British timber buildings.


 The Unshakeable Ethics: When “No” Defines Excellence
As opposed to competitors who silently follow cost reduction directives, Factory Cabins is most well-known for halting projects that jeopardise safety.
 Structural Vetoes: Orders that were declined requesting 19 mm floors (compared to their 28mm standard) even though it saved £2k—”Would you let a garage install budget brakes?” (Price depending on the size of the building.)
 Material Sovereignty: Requires Scandinavian Swedish KD Northern Spruce (FSC certified) for its Arctic density and natural rot resistance—rejecting cheaper “whitewood” for warping in seasons.
 Glazing Integrity: Toughened double-glazing is standard in all windows/doors—no £420 “security upgrades” for basic safety.

We’re not martyrs—we’re mechanics. Safety isn’t an add-on; it’s the blueprint.”



Engineering Beyond Trends: The Twinskin Revolution
Factory Cabins pioneered Britain’s first commercial Twinskin system 20 years ago—a design now relentlessly copied but never equalled. Their secret? Customisable physics:
 Feature  Industry Standard  Factory Cabins Standard  Why It Matters

 Wall Construction Single skin 44 mm, twin skin 44 mm + 44 mm or 70 mm + 70 mm, 90 mm + cavity for 200mm insulation
 Value of Insulation: U-value: ~1.2 W/m²K; U-value: 0.15 W/m²K  60% reduction in heating costs, near NET ZERO.

 Window Security  24 mm single-glazed doors, 28 mm multipoint tilt and turn, football impact resistant, and BS EN 14449 certified
 Lifespan: 5 to 10 years  Exceeding 50 years  15-year warranty against stains; stability of Siberian Spruce 
The cavity is your canvas: Want 200 mm rock wool for Scottish winters? Or minimal insulation for a garden studio? The void adapts to your climate, not marketing fluff.



The Timber Bible: Arming Buyers Against Industry Lies
While rivals hide behind glossy brochures, Factory Cabins exposes the dark underbelly of timber construction via 120,000+ words of forensic guides; please visit our blog.
 The 6Point Quality Framework: Recognise inferior cabins by checking purlin depth (theirs is 45×250 mm compared to a poor 45×150 mm), timber density, and FSC certification.

Myth Busting Masterclasses apex roofs? Half the load-bearing capacity.

PVC windows in log cabins are not a clever idea. Guaranteed cracks as timber breathes and moves, and our CNC wooden windows are built with joinery glulam, giving them strength and flexibility; they never warp, leak, or crack.”
 Explaining the ‘Why’: Kiln drying science (12% moisture stability), fire-retardant treatments.

Factory Cabins Twin Skin Log Cabins: Original 200mm Void Insulation Pioneers

Beyond the Log: How Our Twin Skin System Creates the best Twin Skin Log Cabins in the Industry.

Buy from the manufacturer, not a reseller.

Factory Cabins as the Unequalled Kings of Insulated Luxury

The songs of the bush, the warmth of a campfire, the tranquility of nature – holiday parks and caravan parks give us an escape we all need.

But for the owners of these parks, creating accommodation that delivers real comfort, year-round appeal, and long-lasting quality is crucial. 

Customers want more than a simple form of accommodation they desire a secure and cozy retreat. 

Here, Factory Cabins transforms the industry with its innovative Twin Skin Log Cabin System, setting the standard higher. Forget about conventional log cabins; we produce excellent, well-insulated havens, and the following are some of the reasons we excel compared to others. Factory Cabins was the first to introduce , which means, design, test, manufacture and sell to the public, then other mills saw the light, but sadly pay day, we see the silence, the workmanship, the needed CNC machinery, to manufacture not just an excellent twin skin cabin, but a market leader. And to offer our customers the best.

Our Unbeaten Engineered Twin Skin Log Cabins are designed to stand up for 50 years plus, and save customers money!

The secret is not only insulation, but the way it’s included, protected, and maximised. Our Twin Skin system is not an afterthought; it’s a revolutionary re-design of log cabin architecture. All our Twin Skin log cabins are constructed from FSC Swedish spruce. Which is tight grained and not baltic pine. We only use slow grown timber, this is part of the key to the longevity of a cabin.

Different companies need to understand that our cabins are not just the best in regards to quality and price but also when it comes to construction and durability.

We offer the Following!

Holiday park cabin suppliers.
Insulated holiday lodge supplier.
Luxury camping pods supplier.
Year-round holiday cabins.
Energy efficient holiday lodges.
Twin skin holiday park cabins.
Premium log cabins for campsites.
Commercial grade log cabins.
Turnkey holiday cabin solutions.
Low energy holiday units.

1. Precision Timber Core (70mm x 70mm): Each of our twin skin walls starts with a 70mm x 70mm profile of matured Kiln-Dried (KD) FSC Swedish Spruce. This is not ordinary timber. KD ensures stability, minimizing shrinkage and warping. FSC certification guarantees sustainable, responsibly sourced timber. Swedish Spruce is renowned for its strength, straight grain, and natural resilience. This core provides the stability and beautiful appearance log cabins are so prized for.

2.  The Engineered Void (200mm) First and foremost, we don’t simply fill volumes of insulation into gaps between logs. We establish a precise, 200mm void space between inner and outer log bark skins. This isn’t an error – it’s an engineered chamber with a variety of essential functions:

Optimum Depth of Insulation: This generous margin of error eliminates any necessity to compress thick high-R-value insulation (mineral wool or rigid board). Compression is the R-value bane of insulation. Our void leaves insulation at its highest-rated performance, creating a world-class thermal barrier. That means cabins stay warmth-easy in winter and radiantly cool in summer – cutting park owners’ energy bills in half and enhancing guest comfort.

Hidden Infrastructure: Services, pipes and other cables must run cleanly and safely through. Our 200mm void offers the ideal, safe route. No ugly surface trunking, no reduction in depth of insulation to accommodate services, just a clean, professional internal and external finish.

Ventilation & Moisture Control:Adequate air movement in the void must be supplied to prevent condensation and ensure maximum timber and insulation longevity. Techniques for good vapour control and ventilation of such a cavity are part of our system design. 3. The Locking System designed by Factory Cabins: A cabin is only as good as the joints. if stacked badly it can be too weak an advertisement to characterize our logs, precision made to fit together like a glove. Each log features advanced, interlocking profiles with the advantage of state-of-the-art CNC equipment. Every time.

Seasoned KD FSC Swedish Spruce: We demand the finest raw materials. No green wood, no dubious origin. Just stable, long-lasting, lovely, and sustainable spruce.

Zero Corners Cut: From timber selection through to final quality inspection, our process is rigorous. We take the time over quality because we build cabins that will stand the test of decades in harsh holiday park environments. Complete Automation and CNC Accuracy: Our entire production process is fitted with the most modern CNC equipment. This provides complete consistency, perfect machining of sophisticated joints, and an efficiency that adds value. Each cabin enjoys the benefit of this industrial-level accuracy.

Seasoned KD FSC Swedish Spruce: We demand the finest raw materials. No green wood, no dubious origin. Just stable, long-lasting, lovely, and sustainable spruce.

Zero Corners Cut: From timber selection through to final quality inspection, our process is rigorous. We take the time over quality because we build cabins that will stand the test of decades in harsh holiday park environments. Complete Automation and CNC Accuracy: Our entire production process is fitted with the most modern CNC equipment. This provides complete consistency, perfect machining of sophisticated joints, and an efficiency that adds value. Each cabin enjoys the benefit of this industrial-level accuracy.

4. Real-World Failure Modes: Why Masonry Fails

Brick Cracks extend along mortar joints (the weak point). Ground movement causes diagonal shear cracks. Freeze-thaw cycles break up faces.

Corrosion of Concrete Steel leads to explosive spalling. Inadequate curing develops micro-fractures. Brittle failure happens without any warning.

– *Twin Skin Cabin*: Wood’s fibrous matrix halts crack growth. Redistribution of loads inhibits localized failure. Despite severe force, joints compress but retain.

5. The “Hidden” Structural Benefits*

Computerized Accuracy: CNC machining maintains logs within <0.5mm tolerance. The tolerances in bricklaying are over 5–10mm—leading to inherent weakness.

– *Foundation Efficiency*: Brick/concrete requires deep, expensive foundations. Our system uses small concrete pads as lightweight timber spreads load evenly to soil.

Time-Dependent Strength, Timber increases in strength with age in compression. Mortar weakens; concrete creeps and loses strength.

Conclusion: Moving Beyond “Thick” vs. “Thin.”.

Strength isn’t mass—it’s *intelligent material application and system design*. Factory Cabins’ twin skin technology takes advantage of:

1. Timber’s inherent elasticity,

2. Redundant load paths provided by double skins,

3. Insulation as a structure binder

4. Precision engineering serves to eradicate vulnerabilities.

A 100m² masonry structure may appear hefty, yet physics favours the *adaptive, fault-tolerant strength* of our twin skin solution. Not only is it stronger—it’s provably resilient where masonry isn’t.

Holiday letting is on the rise, with travellers seeking unique, eco-friendly retreats in the great outdoors. For entrepreneurs wanting to reap dividends with a minimal level of input, twin skin log cabins represent a first-rate solution. They fuse tough character with refined efficiency, delivering exceptional visitor experiences and high profit margins. Here’s why investing in a twin skin cabin is your best option in 2025.

The. Financial Advantage: High Returns, Low Costs

1. Better Occupancy Levels:

Twin skin cabins have year-round popularity due to their unmatched insulation. The double-wall construction—usually 44mm or 70mm logs with a 100mm air gap covered with mineral wool or foam—forms a heat barrier that keeps warmth in during winter and interiors cool during summer. This means lower energy bills* (savings of up to 40% compared to conventional cabins) and stable guest comfort, generating off-season bookings.

2. *Premium Rental Pricing:*

These cabins are more expensive per night. Their luxurious appearance, customised designs (e.g., loft areas, terraces), and eco-friendly status make them attractive to visitors who want upscale accommodation. Twin skin case studies show they perform 20–30% better than standard rentals in revenue.

3. Minimal Maintenance, Maximum Durability*: Constructed from *Scandinavian spruce or joinery glulam wood, twin skin cabins are weatherproof, rot proof, and insect-proof. Having a double wall, they distribute even weight to counteract snow, wind, and rain. This minimizes long-term maintenance costs—a critical advantage for busy hosts.

Market Demand: Meeting Travel Trends

Eco-Conscious Travelers: 67% of visitors value sustainable stays. Twin skin cabins, constructed from carbon-storing wood and designed for energy efficiency, access this demand.

Experience Seekers: Cabins offer “Instagram-able” seclusion, mixing old-school charm* with modern luxuries like hot tubs and smart heating.

Easy Setup: Pre-assembled kits from the factory install quickly, accelerating your time-to-profit. Some models (i.e., 4m x 5m models) even skip planning permission issues.

Real Return on Investment: Statistics and Analysis

Even a small 4m x 5m twin skin cabin 70mm x 70mm with a void of around 150mm (with bedroom/shower room) will generate £15,000–£20,000 per year on websites like Airbnb, paying back its price in 2–3 years.

The worldwide log home market should reach *$13.38 billion by 2029*, driven by tourism and work-from-anywhere trends.

Properties that have *energy-efficient features* see 8–10% higher occupancy and 5% higher nightly rates.

Getting Started: Keys to Success

Location Strategy: Place cabins near nature attractions (hiking paths, lakes) to benefit from high-demand locations.

Smart Customization: opt for double-glazed doors reinforced roofing, and terraces to enhance appeal.

Sustainability Marketing: Highlight insulation specifics and net-zero capacity in order to attract eco-friendly tourists. Pro Tip*: Pair your cabin with dynamic pricing software and local experience packages (e.g., guided hikes) to maximize revenue. 

The Bottom-Line Twin skin log cabins aren’t simply a trend; they’re a *future-proof investment*. With their combination of resilience, energy efficiency, and attractiveness, these structures are a passive income stream that increases with each passing year.

For entrepreneurs ready to take advantage of the move toward experiential vacations, these cabins represent the fastest way to large returns.

Timber Frame Revolution: Factory Cabins Ltd’s Ultra-Insulated Net Zero New Builds Redefine UK Living

The UK’s Housing Crisis Meets Its Solution 

As Britain accelerates toward its 2050 net zero deadline, Factory Cabins Ltd is pioneering timber-framed homes that don’t just meet targets—they obliterate them. Our ultra-insulated net zero new builds fuse military-grade thermal engineering with breath taking design, proving eco-homes needn’t compromise on comfort or curb appeal. Here’s why we’re rewriting the rulebook: 

1. Insulation Mastery: The Science Behind Our Timber Frames 

Where traditional builders slap on fibreglass, we engineer multi-layered thermal fortresses: 

– Structural Insulated Panels (SIPs): Factory-precision panels with PIR (polyisocyanurate) cores achieving U-values of 0.10 W/m²K—triple the performance of standard builds. 

Thermal Wraps: Continuous external insulation blankets (phenolic foam/EPS hybrids) eliminate cold bridging. 

Airtight Seals: Butyl tape junctions and gasket-sealed joints lock heat in. 

Hybrid Cavity Systems: Rock wool batts + aerogel-infused boards combat thermal drift. 

Mass Insulation Philosophy: Dual-layer timber studs with interstitial insulation create “thermal mass without masonry”. 

Result: A massive 90% less energy demand vs. conventional homes—translating to £1,200+/year saved on bills. 

2. Triple Glazing: Precision-Engineered Fenestration 

We treat windows as integrated energy systems, not afterthoughts: 

– Argon-Krypton Fusion: Gas-filled cavities with low-emissivity coatings reflect 98% of radiant heat loss. 

– Thermally Broken Frames: uPVC/composite profiles prevent condensation bridges. 

– Factory-Fit Perfection: Glazing units capped into panelised timber frames during manufacturing—ensuring zero air leakage. 

 3. Cladding Innovation: Beauty as Armour 

Break free from “eco-box” aesthetics with our defence-grade exteriors: 

– Brick Slip Systems: Authentic clay veneers bonded to insulated boards—heritage charm with 0.35 W/m²K thermal performance. 

– Rainscreen Tiles: Terracotta/cast stone tiles hung on ventilated battens—dramatic visuals that shield insulation. 

– Metal Hybrids: Zinc-aluminium cassettes over cork-based insulation—sleek, self-healing, and recyclable. 

– Textured Renders: Through-coloured silicone finishes applied over wood-fibre boards—seamless, crack-resistant skins. 

No more choosing between period charm and Passivhaus performance. 

 4. The Net Zero New Build Advantage 

Timber framing isn’t just structural—it’s strategic: 

– Carbon Capture: Every cubic metre of timber sequesters 1 tonne of CO₂. 

– Speed-to-Occupancy: Weathertight shells in than 14 days vs. 3+ months on site. 

Please remember we only build up to first. fix.

– Waste Reduction: 90% less landfill debris vs brick and block. 

 Why the UK Must Choose Wisely 

With energy prices volatile and EPC standards tightening, Factory Cabins Ltd delivers: 

– Future-Proof Investment: Net Zero New Builds appreciate faster as regulations tighten. 

– Energy Sovereignty: Halve bills while dodging fossil-fuel volatility. 

– Design Freedom: Planning-friendly facades from Cotswold stone slips to brick slips, timber, or mixed materials. We don’t just build houses—we craft climate-resilient legacies.

Bespoke 4m x 7m 44mm x 44mm Twin Skin Log Cabin.

Hi all, another post, and this one has a long story attached to it.
We first started working with our client (Jackie) 4 years ago; she had 1001 questions and her desire to have the best log cabin she could afford. And she was going to save up because she said we manufactured the best, and she wanted the best!

What she wanted was a place where she could clean her pets and also chill out, watch TV, drink a cup of tea, with no loud noises, in her garden; all she wanted was peace!


What was very important was that it would hold all that Mother Nature could throw at it, as she is in the top end of Scotland, where the weather is one minute sunny then pouring down with rain.

Bespoke 4m x 7m 44mm x 44mm Twin Skin Log Cabin

Jackie only wanted one from our cabins, as she was sure that we sold the best, plus we could easily bespoke it to her needs. Jackie had also spoken to a few of our other customers and had asked them about the quality, etc. Also, we said please look around and then, if they are happy, come back. Jackie and her husband, Gerry, decided to visit every dealer in Aberdeenshire and the surrounding areas and check what else was available and what the pricing was on offer. They were looking for quality, and Jackie had read quite a lot of my blog. So she knew what’s what.

So here are some photos of their build. And the outcome.

So the concrete base went down, and as you all know, bad base, bad build. All flooring was impregnated and dampproofed.

Our internal doors for all our log cabins are superb quality.

All windows and doors are treated before they are put into place. Our windows and doors are manufactured from Joinery Glulam; we are not very keen on putting plastic, cheap windows and doors into our cabins (which are sold as an expensive upgrade) as we are able to manufacture the best joinery wooden ones, double-glazed tilt, and turn on our new CNC window and door line.

Bespoke 4m x 7m 44mm x 44mm Twin Skin Log Cabin

A lot of the mass-manufactured cabins may have an upgrade offered on their websites from their cheap, awful windows and doors, and then they offer plastic. The reason for this is obvious: they cannot manufacture quality. This is the first sign that what you are thinking of purchasing is mass-manufactured rubbish! The price is tempting, but the quality is poor!

Twin skins are perfect for all seasons, and as the first to manufacture these and design this system, I think we know what we are talking about!

We do not have missing bits, and that one thing for you is a blessing.

We use Swedish timber, which is now the best on the planet to manufacture your log cabins from? The Swedish know how to cut and prepare logs.

Bespoke 4m x 7m 44mm x 44mm Twin Skin Log Cabin

It’s really important to know what you are buying, who you are buying from, and always remember that purchasing your cabin from the best means your cabin will last you the test of time; cheap means a few years; our means 30 years plus.As long as you stick to our terms and conditions.

If it rains, you must always have a cover ready to put over the building; we do not want damage, you do not want damage, and if you listen to us if your doing a self-build, there are a few things you must have at hand. Jackie and Gerry listened to us, and that’s why their build was spot on in every sense. Plus Gerry did not screw the logs together, who in their right mind came up with this idea—madness, stupidity at the lowest level. The logs must settle, and if you screw them together, when they shrink, it leaves gaps—rather large gaps.

The great thing about twin skins is that you can hide all the wires in side the viod.

A small scaffolding tower is best to have at hand. Health and safety first…

Add a protective layer of water proof paint on the roof boards a very clever idea.

You must let this dry before you move forward.

Then… battens, insulation, and OSB.

And on top of that, a felt roof. Wow, not finished yet.

Then shingles! Yep. An all-weather log cabin… only from factory cabins.

Looks solid!! This cabin can be slept in in minus 30 easy!

Now inside…….

Doing the floor is a quality job, as its the last thing to do, and it’s actually the hardest, as you must make sure you have done all your calculations so they are correct. The floor must be spot on!

Massivley insulated floor, base, and well done.. Superb!

So if you are looking for a high-quality insulated twin-skin log cabin, please give us a call.

Incredible Quality Insulated Twin Skin Log Cabins

Let’s talk about “Twin Skin” log cabins, something we at Factory Cabins are absolute experts on! Why are we the experts, Because we designed the twinskin system.

We were the first to design, manufacture, and bring to market, all others are copies of ours! We went through the whole trial and error.
Understanding how to manufacture a twin skin correctly is a task in itself. Everything must be calculated precisely.

These are not your basic log cabins. These are ( Incredible Quality Insulated Twin Skin Log Cabins)

Twinskin ones have become sought-after lately, all thanks to their unique design and plenty of benefits.

So, what makes them so special?

Twinskin log cabins, or, if you like, call them double-skin or twin-wall cabins, have an innovative construction with two separate walls.

This is a big jump from the usual one-wall affair in traditional log cabins. Here’s the best part: there’s an air cavity right between these walls acting as insulation!

That means superior thermal performance, making your cabin energy efficient. Let’s dig a bit deeper into how they’re built.
You start by assembling two different walls with top-notch Swedish spruce logs. Why? The sturdiness and thermal characteristics of these logs ensure you get a solid structure that keeps cosy very well indeed.

Now remember the air cavity I mentioned earlier. Some sort of insulating material (perhaps mineral wool or foam) fits right in there, optimising thermal efficiency.

It’s probably clear by now that the high level of insulation is a major feather in the cap for Twinskin log cabins!

That little cavity does great work as a barrier against heat transfer – so it’ll keep your cabin cool during the summer and warm in the colder months without needing extra heating or cooling units around, thus saving energy.

The double-wall structure isn’t just for show – it multiplies durability too! These two walls divide up weight equally and battle external strains from wind to snow loads, ensuring longevity for your space.

Now onto another plus point: customisable designs! With extra insulation to play with, twin skin log cabins give you more freedom to play around durably with larger windows and doors without cutting down on energy efficiency, Flexible interior design options further add creative flexibility to how you want things done inside!

(Incredible Quality Insulated Twin Skin Log Cabins)

Surely this awesome level of insulation means energy efficiency is taken care of.

Absolutely right! Lower utility costs, less heat loss during the winter, and limited heat gain in the summer seasons mean the living conditions inside remain comforting while trimming down on environmental impact.

It’s a massive economic and ecological win!

Why should you think about including a Twinskin Log Cabin on your land?

Well, it’s simple: they are comfortable, durable, and offer great energy efficiency, regardless of whether you’re aiming for a home away from home hideout or scouting out your new permanent residency. These log cabins tick all boxes that combine optimal functionality with gorgeous aesthetics.

So, to sum things up: twin skin log cabins redefine traditional log cabin construction, boost insulation abilities, strengthen durability, and increase energy effectiveness.

And at Factory Cabins, we’re all about giving you quality options that meet your exact needs or go beyond them. We’re ready to start whenever you are!
