Cavity Injection Spray Foam

Sunny South Insulators has developed an innovative way of inserting spray foam by injection into older buildings that are not easily accessible. Icynene® spray foam expands to fill the empty cavity space. This allows homeowners the ability of increasing insulation R-value at a much lower cost than having to complete and full scale renovation.

Since Icynene® expands in the direction of least resistance, it will not expand outward and damage the wall. Injection fill foam has an R-Value of at least 3.7 per inch. 

Other value added benefits of using Icynene cavity fill foam for your building:

  • Reduces energy costs
  • Enhances sound proofing
  • Improves indoor air quality

I had no idea that any one product could do so much for our homes as well as benefit the clients. We were able to reduce our energy consumption dramatically, which reduced our energy bills.
