Spray Foam Insulation Benefits:
Energy Savings
Research shows that 40%-50% of the average home’s energy losses are from air leaks in the walls and ceilings.
Why is so much energy lost in this way?
Air Flow
Fiberglass and cellulose products cannot stop air flow through and within the wall assembly. This air flow significantly reduces the performance of both of these traditional insulation products by allowing conditioned air to escape and also allowing hot/cold convection loops to form within the wall cavities. This greatly reduces the efficiency of an insulation system and air blowing through a wall represents a complete insulation failure.
In contrast, open and closed cell foams do not allow air to move in convection loops within the insulation system. Spray foam fully adheres to the wall cavity and allows no gaps or voids for air travel within the insulation medium.
Moisture
Fiberglass is vulnerable to damage from moisture.
Closed cell foam is FEMA approved for submersion in water for 72 hours without any damage.
Filling the Gaps
Fiberglass cannot completely conform to wall penetrations and oddly shaped wall cavities.
Foam expands 30 to 150 times its original volume, filling every nook and cranny without any difficulty or loss of R-value.
Temperature Change
Fiberglass performs at significantly reduced efficiencies in extreme weather conditions.
Foam is affected by temperature differences much less than fiberglass.
Other Spray Foam Insulation Benefits:
- Spray Foam offers improved indoor air quality compared to traditional insulation materials.
- Closed cell foam is a class 2 vapor barrier.
- Neither open cell nor closed cell provides a food source for mold or rodents.
- Closed cell foam also strengthens a wall 200% to 300%.
- Increased structural integrity results in a quieter home.
