Spray Foam Insulation FAQ ’s

With the rising popularity of spray foam insulation, many homeowners are looking into the product to try and determine whether it’s a good fit for their homes and their lives. Most people find that they have questions regarding spray foam insulation. Read the helpful FAQ’s below to learn more about spray foam insulation and how it can make a difference in your home.

Here are a few Spray Foam Insulation FAQ ‘s

1.) Is spray foam insulation approved for use in residential buildings?

Yes. Building codes are now updated to include guidelines for the use of polyurethane spray foam insulation. It is usually listed in the plastics section or where the building code talks about the use of thermal barriers.

2.) When should spray foam insulation be applied?

If constructing a new building, it should be applied at the same point in the construction cycle that traditional insulation would be applied. That means it will go in after the rough plumbing, electrical wiring and heating systems have been installed. If you seal the exterior shell with insulation, it may need to be applied before some areas of ductwork are installed.

3.) Can an average homeowner apply spray foam insulation?

Yes, but it isn’t practical. There are DIY kits available, but they require complex equipment and a steady hand. Professionals are trained in the safe use and proper handling of the system.

4.) Can closed-cell insulation be used to prevent flooding in a home located in a flood zone?

If your home is located in a flood zone, closed-cell spray foam insulation is a good choice. The insulation is listed as a class 5 flood damage-resistant material according to FEMA, which means it’s highly resistant to flood water damage and damage caused by moving water. The foam insulation survives wetting and drying and can be cleaned after a flood to remove harmful pollutants. It is the only insulation material that has this designation.

5.) Are spray foam insulation scraps toxic?

There is little knowledge about how scrap materials interact with soil in landfills or other disposal situations, so the toxicity of the product is not known. Dispose of scraps like you would normal construction debris.

6.) Should I ventilate my home if I install spray foam insulation and have a fire place?

Ventilation is a critical step in the insulating process. Most ventilation in homes occurs in the attic. If you have ducts above the attic floor, insulate the roof deck, otherwise insulate the floor of the attic.

7.) Can spray foam insulation reduce noise?

Yes. To help reduce noise through a wall or other surface, either open or closed cell spray foam insulation can be used. The choice will depend on the structural needs of your building, your budget and the climate you live in.
