The insulation values of building elements, is one of the main focuses of this part in conjunction with the allowable area of windows and doors, the air permeability of the structure and the heating efficiency of boilers. The combination of these make up the input requirements for SAP (Standard Assessment Procedure) and calculations for Carbon Emissions.
We are commonly asked how well our log walls perform as an insulator (what u-value we can achieve). This is an important factor when choosing how to construct your home as the materials used in its construction will directly affect how energy efficient the building will be. Currently our log walls achieve a u-value of around 0.54. From a design perspective we try to specify as much additional insulation as possible. This is generally placed in stud lining to the inside of the cabin around kitchens and bathrooms where a flat wall finish is required for tiling or for hanging cupboards. This compliments feature log walls throughout adding to the log home's aesthetics.
It is important to think about the energy performance of a building at the design stage. Building regulations are evolving, focusing more on sustainability, quality and efficiency. If regulations are taken into account from the onset of the project then the best compromise can be found between energy efficiency, practicality, aesthetics and budget.
