The Pros and Cons of Spray Foam Insulation

Whether you’re building an energy-efficient home or just sprucing up the basement, spray foam insulation can be one of the best investments you make. While homes insulated with spray foam often outperform fiberglass batts in terms of efficiency and comfort, the product isn’t without its drawbacks.

Which insulation is best for walls?

Spray foam insulation is a composite material consisting of liquid chemical ingredients that react on contact to expand and harden into a thick, rigid insulation. The material can be sprayed onto walls, nooks and crannies, and rafter spaces to create a custom airtight envelope within the structure. Source : www.armorinsulations.com

Closed-cell spray foam insulation also acts as an air and vapor barrier in one, so homeowners don’t have to install another vapor barrier on top of the dry foam. This is a major benefit for those concerned about moisture, reducing the amount of chemicals that may off-gas into the interior of a home, and lowering construction costs.

However, the blowing agents used in spray foam are not good for the environment. The common HFC (hydrofluorocarbon) chemicals have a global warming potential of over 27 to 30 times more potent than carbon dioxide. This means that insulating 1,430 homes with spray foam will do as much atmospheric damage as was done by just 1 house using the old fiberglass insulation.

Professional installation is important when insulating with spray foam. They’ll have the equipment, expertise, and warranty to ensure a quality job. You can also vet a builder by asking for references, and finding out how aware they are of the off-gassing issues.
