Lightweight concrete is ideal for highest thermal performance concrete masonry wall assemblies whole wall r values for.
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.
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.
This is how the dynamic mass wall performs in whole wall lab tests and in the constructed home.
Above grade concrete wall including inside and outside air films r 1 2 for 6 inch r1 4 for 8 inch concrete block wall with air in cavities r 2 0 concrete block wall with perlite in cavities r 2 9.
Block and cavity fill.
To determine the value for all wall.
Add the individual components and then multiply by 11 and divide by 5 per fsec.
