Vinyl Siding
A section of the vinyl siding is taken off in order to insulate RetroFoam in between the studs. It is carefully put back on after install.
Interior Wall Insulation
Most of this home was insulated from the outside, but to ensure that every single area was evenly insulated with RetroFoam, installers injected foam from the interior on this small section.
Every Corner Accounted For
Installers make sure every corner is injected with RetroFoam.
