    CHOOSE YOUR LOG CABIN WALL THICKNESS: Which one is best for me?

    Which wall thickness and cabin specification is best for you?

    Insulating the roof and floor of a single skin cabin dramatically improves their usability (warmer in the winter and cooler in the summer), but a Twin Skin is far superior. The table below shows the values achieved with Hortons log cabins (the lower the U value, the better it is).

    Cabin Specifications U-value of Building (W/m²K)
    28mm log cabin, no insulation 2.56
    45mm log cabin, no insulation 2.28
    28mm log cabin, with just roof insulation - no floor insulation 1.78
    45mm log cabin, with just roof insulation - no floor insulation 1.48
    45mm log cabin with roof and floor insulation 0.84
    70mm log cabin with roof and floor insulation 0.81
    Hortons Insulated Twin Skin Log Cabins
    35+35mm Twin Skin log cabin with standard fiberglass insulation kit 0.6
    35+35mm Twin Skin log cabin with standard Celotex insulation kit 0.35
    45+45mm Twin Skin log cabin with standard Celotex insulation kit (50mm wall cavity) 0.34
    45+45mm Twin Skin log cabin with non-habitable UK Building Regulations Celotex insulation kit (90mm wall cavity) 0.23

    For realistic comparison purposes, this is a table showing the U values required by UK Building Regulations for homes over

    the years, so you can see how the insulation of our cabins compare with houses built through the decades -

    7x4m insulated garden office

    This insulated Twinskin pent Basildon cabin garden office cabin was made slightly smaller at 7x4m and modified by removing the right gable end window. The remaining windows were all upgraded to simple tilt & turn, 2 trickle vents added and it was built onto our damp proof membrane kit for long life.
