How is the wall form insulated?
At the factory, prior to shipping, we insert 3 inches of mineral wool insulation or polyisocyanurate insulation into the interior cells of each block. By inserting this insulation into the cell, on the side of the wall form that will be closest to the outdoors, your inside temperature swings are moderated. Essentially, the thermal mass is insulated into the building, thereby reducing your heating and cooling bills. Mineral wool is also a recycled product being made from the slag produced in the steel making process. It allows air and moisture to pass through the wall and does not rot or decompose.
