Our Log Cabins are available in a range of wall thicknesses; 28mm, 45mm, 130mm or 145mm
If you intend to use your cabin all-year-round - rather than seasonally - you should choose as thick a wall as possible, to maximise the insulation. U-Values
provide a measure of the heat transfer through different materials, to allow you to compare options we quote the U-values of the walls below.
We use interlocking tongue & groove timber in our walls to provide strength and stability, it also allows timber to naturally expand and contract.
Our 28mm walls
are almost 50% bigger than a 19mm wall and are ideal for larger buildings for seasonal use. (U-Value 2.59 W/m2
Our 45mm walls
contain over 60% more wood than a 28mm wall and are ideal for use all-year-round. (U-Value 1.93 w/m2
Our 130mm walls
are a cabin-within-a-cabin. We recommend these for home offices and cabins being used all-year-round. (U-Value 1.28 w/m2
k without insulation) (U-Value 0.29 w/m2
k with insulation)
The 130mm walls
consists of one 28mm external wall, 70mm air gap (which can be filled with Polyurethane insulation. See step 3 'Insulation Options') and a 28mm inner wall. The two walls are not connected to each other - unlike competitors systems - to ensure that; as the outer wall expands and contracts with changing weather, and the inner wall dries out in a warmer environment or soaks up moisture from excess trapped humidity, that the two walls don't pull each other in separate directions or create gaps since they are not connected together unlike the competitors alternative.
The 145mm walls
have a 70mm air cavity in between walls which in itself provides more insulation than just the timber alone giving a U-Value of 1.28 w/m2
k. If you opt to purchase the Polyurethane 'Wall Insulation', we will supply you with 70mm thick Polyurethane insulation. This is a fantastic insulator, and far more effective than rockwall or polystyrene, and brings the U-Value down to just 0.29 w/m2
k. This insulation helps reduce heating costs further and is ideal for anyone who intends to use their cabin all year round.
The 145mm walls
have a 70mm air cavity left unfilled, without any Polyurethane insulation in the walls, has a U-Value of 1.09w/m2
k proving that it provides more insulation than the timber alone. If you chose to opt for our Polyurethane insulation which, as an insulator is roughly twice as thermally efficient as loft insulation, gives the wall a U-Value of just 0.26 w/m2
