Most wood framed stucco homes in the Valley never had a wall insulation inspection when they were built.
Most wood framed stucco homes in the Valley never had a wall insulation inspection when they were built. As a result they are poorly insulated. Most homes are missing insulation in some areas, and the insulation they do have is not installed correctly.
Wood Framed Walls In Phoenix Have Zero Air Seal, And Usually Have An Effective R-Value of R5 or Less
In order for fiberglass insulation to perform to its specified R-Value it needs to be installed over an air sealed surface. Arizona cities have never enforced this requirement and homes being built today are built without an air seal in the wall. These manufacturing defects cause heat to quickly flow to a wall and into a home.
Foam Insulation Creates A 100% Air Seal, And Can Increase The R-Value Up To R-26
A foam sealed wall exceeds all code standards. It slows the heat transfer through the wall significatnly, which allows the AC to run less and the rooms to stay comfortable.
