K. This may just seem like a strange number but
this means that your house will be losing less than half the heat of the houses around yours. Not only is
less heat lost into the environment but also less fuel is used in heating (this also benefits your pocket!).
The basic material that we are using is timber which is a totally renewable and clean resource. By using wood
we leave the landscape as it is. There is no need for quarrying and the such like. The amount of energy needed
to get wood into a workable state is much less than the amount needed for other materials such as bricks
or concrete.
The wood is 100% usable as the left over peices, such as saw dust, has many uses. For example, it is used for such things
as heating pellets or insulation.
