Cavity Wall Insulation

We apply closed cell spray foam in two different ways. These are spray application and slow pour formats.
The slow pour method is recommend for the exterior walls of a house. And the spray application for interiors.
The spray foam is poured into the cavity slowly to fill every gap. It is designed to adhere to both the inner and outer blocks. This creates an airtight and waterproof barrier.
This method is common for older houses that were built without insulation between the block walls.
