Spray Foam Insulation R-Value and air sealing in one
Spray foam is an amazing product that not only provides a high R-value but also works to seal your home from air infiltration. Air sealing is actually more important than insulation in that is prevents air leakage in your home and increases overall efficiency while preventing dust, insects, and odors from entering your living space.
Insulation Removal
Typically spray foam is applied to the underside of the roof deck which brings the attic into the "conditioned space" of the house. It is essential that old blown-in insulation be removed so that any odors, mold, insects or rodents are not present in your living space.
Blower Door Testing
The blower door test is the industry standard for measuring air leakage of a building. At NAJ Spray foam we perform a blower door test before and after our insulating service to prove our results. Air leakage is measured in Air Changes Per Hour (ACH) and we can back up our service with science!
Spray Foam Insulation
Spray Foam has been a game changer in the insulation industry. Fiberglass, Rockwool, and Cellulose are all good insulators but they are missing a key component to achieving energy efficiency. Spray foam is not just an insulator but also an air sealer. Reducing the exchange of air from the inside to the outside along with a good HVAC system is a critical part of achieving energy efficiency in both residential and commercial buildings.
