Performing attic insulation removal can be necessary for several reasons. Over time, insulation can become less effective due to damage, infestations, or contamination, impacting its ability to regulate temperatures and energy efficiency within your home. Old or compromised insulation can lead to decreased indoor comfort, higher energy bills, and poor indoor air quality. Additionally, aged insulation might contain harmful substances or allergens, posing health risks to occupants. By removing old or damaged attic insulation, you create a clean slate for the installation of new, more efficient insulation. This process significantly improves the thermal efficiency of your home, enhances indoor comfort, reduces energy expenses, and ensures a healthier living environment.

Insulation removal is essential for air sealing the attic floor and spray foaming the roof decking to create a conditioned attic space. Removing the insulation allows access to the entire attic floor, making it easier to pinpoint and seal all potential air leaks between the attic and the living space. It also eliminates the need to "swim around" in insulation hunting for air leaks, which can be time-consuming and challenging. Additionally, removing the old insulation before spray foaming the roof decking ensures that the foam can create an airtight seal around the exterior top plates. Finally, removing the old insulation removes a potential source of dust, mold, and other allergens now that the attic space is connected to the house in a conditioned attic. It is important to note you do NOT want to air seal the attic floor if you are going to create a conditioned attic space with spray foam.
