Expert Tips: Pros and Cons of Spray Foam Insulation

Spray foam insulation is one of the latest and greatest innovations in the construction industry. Unlike traditional insulation materials, spray foam can be applied directly to the interior or exterior of a building, providing a seamless barrier against heat transfer. And because it is applied as a liquid, spray foam insulation can easily conform to any shape or contour, making it perfect for hard-to-reach areas.

​​Most people think of insulation as something that is only used to keep their homes warm in the winter and cool in the summer.

3. Improved indoor air quality:

SPF, or “spray polyurethane foam”, insulation is not your traditional fiberglass insulation. SPF is sprayed into place using a special machine and forms an airtight barrier on walls, ceilings, and around outlets and windows. By sealing the spaces around outlets, windows, doors, and other openings, SPF reduces the amount of pollen, dust, and other allergens that can enter your home. In addition, SPF also helps to block out pollutants from outside sources, such as car exhaust fumes. As a result, spray foam insulation can play an important role in improving indoor air quality.
