Problems With Spray Foam Insulation In Attics
In a vented attic all of that expensive airflow is lost to the environment.
Problems with spray foam insulation in attics. Below we are going to list the most common problems with using spray foam insulation in your home s attic or in any area inside of your home. What goes right and what goes wrong. Insulating with spray foam insulation at the roof line will cause moisture problems with the roof sheathing. In an unvented attic scenario to limit air leakage as well as any associated condensation at the roof line a continuous air barrier is required.
If the spray foam is installed correctly then you can look forward to a home that stays substantially warmer costs less to heat. When we seal the attic with spray foam it s as tight as a butter tub. By doing so you bring the attic inside the building enclosure. One of those problems is moving the building enclosure from the drywall ceiling of a home to the roofline.
Placement errors during installation attics are the main spots in a home that are filled with unusual shapes gaps and spaces where air bubbles have the potential to form when you spray foam insulation. Whereas too little spray foam insulation can leave for thermal bypass because of the complete lack of insulation in the attic. It has been said that insulating with spray foam insulation at the roof line will lead to moisture problems with the roof sheathing. One huge benefit of the spray foam insulated attic is that conditioned air leakage from the ac furnace duct system is contained and used to condition the attic.
If the spray foam is installed incorrectly then a large number of problems can arise.
