The first part of your log cabin you should think of insulating is the floor and roof, as this is the thinnest part of your log cabin and so will benefit greatest. The floor and roof of a log cabin can be easily insulated and this will make your log cabin much more economical to heat in winter and cooling in summer.
Floor Insulation
A water repellent material similar to Polystyrene is very useful for insulating the floor. It is fitted directly under the floor boards and between the floor joists.
Roof Insulation
First fix timber battens to the roof boards running around the edge of your cabin roof, then fix a batten above each roof purlin running the length of the roof. Roof insulation is fitted between the timber battens. If you are using Bitumen roofing shingles then a plywood or similar material is laid over the insulation and fixed into the battens, this gives you a solid surface to fix the shingles onto. If on the other hand you will be using our metal profile roofing then this can be applied directly to the battens, without the need of the extra plywood surface.
