Injection foam is an insulation and air barrier that will seal enclosed cavities such as existing walls against air movement. Injection foam never loses its shape in the cavity, unlike conventional insulation materials like fiberglass and cellulose. Injection foam completely fills the cavity filling in cracks and gaps when it is installed. It doesn’t settle, compress, or sag over time.
Injection foam can be installed into an enclosed cavity, such as existing walls with no need to tear down walls or waiting until you remodel. It can also be installed in concrete block walls to fill the cores.
Foam can be injected with existing walls without removing the outdated fiberglass insulation. If loose cellulose exists, the crews will remove as much of it as possible before injecting the foam insulation.
