Why Foam an Already Built and Insulated Home?

Insulation should keep the temperature inside your home consistent without overworking the furnace or air conditioner.

There are several signs that will indicate that the insulation in your home is not doing its job. Some of the most noticeable will be:

  • Hot rooms!
  • High energy bills
  • HVAC units constantly running
  • Fluctuating temperatures between rooms
  • People in your home suffering from terrible allergies
  • Cold floors in the winter
  • Adjusting what you wear to match the “weather” inside your house

Make a Difference When You RetroFoam Your Home

Lower Energy

Homes with RetroFoam insulation save up to 50% on their monthly energy bills.

Stabilize Room Temperatures

RetroFoam insulation stops air leakage keeping the temperature inside of your home consistent between rooms.


RetroFoam of the Carolinas offers a transferable lifetime warranty for the foam installed during the life of the building.

Create a Healthy

RetroFoam insulation is free of fibers that can retain allergens, cause dust, and irritate skin and airways.

What Areas Of My Home Can Be Foamed?

RetroFoam is designed to establish an envelope around your home creating an air seal that prevents air leakage. This means that RetroFoam can be applied to the areas of the home that separate the house from the outside world.
Create an air seal and prevent air leakage with retrofoam


RetroFoam can be injected into wall cavities from the outside of your home or the inside of your home. In situations where the cavities are open, spray foam is used.

RetroFoam of the Carolinas can install spray foam to roof deck of the attic or the floor of the attic to create an air seal preventing air leakage. 

When insulating basements we recommend insulating the ceiling, walls, and rim joists to establish the air seal needed to stop drafts, condensation, and air leakage.

After laying down a vapor barrier, RetroFoam of the Carolinas uses spray foam to insulate the walls of the crawl space and rim joists. This creates an air seal which prevents drafts and condensation. 

To prevent drafting and condensation build-up along the rim joist RetroFoam of the Carolinas applies spray foam to the rim joist providing you with the air seal your home needs to stay comfortable. 


RetroFoam of the Carolinas can add spray foam or injectable foam to the walls of your garage to help stabilize temperatures and turn your garage into a more comfortable and usable space.
