Strong and Sturdy 45mm Thick Walls

We use interlocking tongue & groove timber in our walls to provide strength and stability, it also allows timber to naturally expand and contract. Don't forget, we also use only slow grown Spruce and NOT cheap Pine! 
 

Our 45mm walls contain over 60% more wood than a 28mm wall and are ideal for use all-year-round. (U-Value 1.93 w/m2 k)
