All about Wall Thickness

Log Cabin Dunster House

If you plan to use your cabin throughout the year, and not just seasonally, you want to maximise insulation by choosing the thickest wall possible. Read all about the log cabin wall thickness and decide which one suits your needs best.

We have created a breakdown of our main four wall thickness options for Log Cabins to help you make an informed decision in choosing a Log Cabin that will meet your needs.

U-value and Wall Thickness

Each short explanation includes a U-Value, which is a measurement of heat transfer through different materials.



Our 28mm walls are 80% bigger than a 19mm wall and are ideal for medium sized buildings for seasonal use. (U Value 2.59 w/m²k)






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/m²k)





Our DualTherm walls are a cabin-within-a-cabin-. The two walls float independently ensuring that as the outer wall expands and contracts in more extreme weather it doesn’t pull the inner wall out of place, a method uncommon with some competitors. The two 28mm walls have a 70mm air cavity in-between to provide even more insulation. We recommended these for home offices and cabins being used throughout the year. (U Value 1.28 w/m²k)





Our TripleTherm walls are the same as the DualTherm. This time the 70mm cavity is filled with polyurethane insulation. It’s more effective than rockwool or polystyrene, helping to further reduce heating costs. (U Value 0.29 w/m²k)



All of our walls are made using interlocking tongue and groove timber to provide strength and stability, it also allows timber to naturally expand and contract.
