No Need to Tear Walls Down
The great thing about RetroFoam is that it can be installed in existing walls without demolition. All that is needed is access to the wall cavities by removing siding during install.
Injection Foam Insulation
RetroFoam comes out like shaving cream, in order to fit inside all spaces in the wall. Then, after 48 hours, it hardens inside for a powerful insulation solution!
