R value of 8 concrete block wall.
The r values u factors listed in this tek were determined by calculation using the code recognized series parallel also called isothermal planes calculation method refs.
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.
Cavity wall r values are listed in tek 6 1c r values of multi wythe concrete masonry walls ref.
Box 513 metuchen new jersey 08840 0513.
Walls are much greater than conventional 3 web concrete block walls.
Block and cavity fill.
This is how the dynamic mass wall performs in whole wall lab tests and in the constructed home.
To determine the value for all 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.
Add the individual components and then multiply by 11 and divide by 5 per fsec.
