Spray Foam Genie Detroit is looking to upgrade their attic insulation with spray foam, and are surprised to learn that the existing fiberglass batt or blown-in insulation must be removed before the spray foam can adhere. There are several reasons why this is necessary.

Existing Insulation Can Be Dirty or Home To Pests

Fiberglass batt and blown-in insulation are both susceptible to becoming dirty from rodent droppings and nesting materials. This is a problem that can cause severe health problems if not addressed with effective rodent control and removal.

The existing insulation can also be contaminated with mold and fungus, which will negatively impact the indoor air quality in your home. It’s important to have the insulation tested for asbestos before attempting to remove it yourself. If it is found, you will need a licensed professional to perform the removal and ensure it’s properly disposed of.

Removing the attic insulation will make it easier to do an attic clean-out, which is required before spray foam can be installed. This will allow you to identify and fix air leaks between your attic space and living spaces that can greatly reduce your energy costs.

It’s also important to remove the attic insulation before doing any work on the roof deck, which is a good time to do some soffit and ridge venting to prevent the attic from becoming a moonscape of cellulose or fiberglass that could have moisture issues in the future.
