Should the Attic Floor Insulation Be Removed When Doing Spray Foam?

Spray foam insulation contractors and homeowners alike have debated this questions over many years and since spray foam first gained popularity in late the 2000’s, we’ve had many case studies to learn from. What is the best practice for homeowners when they are considering spray foaming their attic? In a hot dry climate like Phoenix, spray foam is worth the extra cost and is the ideal insulation method because all of our ductwork and HVAC systems are inside the attic space. Spray foam contractors in Arizona have differed though in their reasoning over if the existing insulation should be removed or kept along the attic floor.

Attic Condensation Via Spray Foam Flaws and Pot Light

Spray foam is usually sold as The Silver Bullet that promises to fix nearly every building flaw. Spray foam is an amazing material, but it's only as good as the installer. I always say Hire the guy pulling the trigger on the spray gun, not the foam brand or contractor.

In the case above, the attic floor had many holes that leaked air from the living space into the attic space as driven by winter-time stack effect. This moist air then condensed as it hit cold roof sheathing and undersides of roof vents. The fix: Seal the holes!

The guy pulling the trigger controls the manufacturing process and performance of the end product: in situ spray foam. If you're installer treats their equipment well, knows the limitations of the foam and has some building science knowledge your off to a good start.
