R Value Of 8 Concrete Block Wall

Walls are much greater than conventional 3 web concrete block walls.

R value of 8 concrete block wall.

The increase achieved by injecting aminoplast foam insulation is up to 264 greater than is possible with normal weight concrete. R value table insulation values for selected materials this method of determining r values do not apply to dynamic mass walls such as the all wall system. This is how the dynamic mass wall performs in whole wall lab tests and in the constructed home. Depending on the density of the blocks an 8 inch thick block wall without any other type of insulation has a thermal resistance value between r 1 9 and r 2 5.
