Does spray foam cause indoor air quality problems?

Any improperly installed insulation has the potential to cause or lead to indoor air quality issues.  This is why it’s very important to choose your insulation contractor carefully, just as you would with any other contractor.  There are also many other building products and home goods, inside your home which have the potential to be the source of indoor air quality issues.  Spray Polyurethane foam insulation utilizes diisocyanate, which isn’t scientifically detectable after 1 hour of when the foam ins applied. Installing spray foam requires a professional certification and proper equipment to install it.  Properly installed spray foam insulation, is an inert plastic and is just as safe as the plastic trash bag in your kitchen trash can.

How are R13 insulation different between fiberglass and foam?

Fiberglass works by trapping air inside tiny glass fibers that contain small bubbles of air, which slows the transfer of heat.  It’s installed by folding, wrapping and cutting pieces to place in stud cavities.  Human installation error coupled with the fact that fiberglass doesn’t hold in heat well and loses 40% of insulating capacity when outside temperatures are below 20° F make it and inferior product, in comparison.  Fiberglass has been laboratory tested to lose 8% of its labeled R-value right out of the bag, and has a 28% loss in R-value as commonly installed. Spray foam is sprayed by a certified spray foam applicator, expanding into all gaps, cracks and cavities and can adapt to any structural design, virtually eliminating human installation error.  Most importantly it’s an air barrier with excellent thermal properties for your home that seals and keeps warm and conditioned air in your home year round.

How much does it cost?

The up front costs for spray foam can be as much as three times the cost of conventional fibrous insulations, depending on your project.  The benefits far out-weigh the difference in the up front costs. With spray foam, you will be more comfortable in your home, which for most is their biggest investment.  Utility bills are documented to be half as much or more with spray foam, which makes for a quick payback period.
