Energy Performance of Log Walls
The most frequently asked questions that we get are around the energy efficiency ratings of our log homes:
- 'What U-Values can you achieve with handcrafted log walls?'
- 'Can handcrafted log walls get through building regulations SAP calcs?'
The short answers are:
- Excellent, but not properly measured. And
The SAP calculations are an average energy efficiency rating for the building. They take into account the number of doors and windows, the level of insulation in the roof and floor, the direction that the building faces, the heating system, the materials used and their thicknesses.
A handcrafted log wall in practice will offer incredible insulation, and out perform any u-values assigned to it by the energy assessor. However, as the log home industry is so small, laboratory tests have not yet been conducted to establish an official rating for a massive handcrafted log wall. This is something that we are currently working to remedy.
During our design and specification stage we look carefully at where we can gain efficiencies whether it be the insulation in the roof and floor, installing super efficient windows and doors or insulating and lining around hidden areas of the home such as bathroom and kitchen walls.
Properly thinking through the specification, design and positioning of your log home means that we can not only pass building regulations requirements but surpass them, currently meeting The Code For Sustainable Homes Level 3.
