Will sealing my building with spray polyurethane foam improve the air quality of the building?
Yes, Spray Polyurethane Foam is a solid inert material that does not have any loose particles or micro particles like those found in a fiberglass or a cellulose installation which can enter the living environment thru numerous unsealed sources, by eliminating those particles and completely sealing the building with spray polyurethane foam, it provides a cleaner healthier living environment.
What are the types of spray polyurethane foam and where is it used?
Spray polyurethane foam (SPF) is a solid foam that can be used to drastically improve energy efficiency in your home. Sealing holes and gaps is the key to energy efficiency.
There are some types of SPF called two-component foam because the chemicals used to make the foam come in two separate containers. The chemicals are mixed and applied using a spray pump or gun. Two-component SPF products come in two types, either low pressure or high pressure systems:
Low pressure: used by contractors or weatherization pros to seal and insulate small to mid-size areas (e.g., crawl spaces, attics, joist retrofit, or to fill seams and gaps in primary insulation).
High pressure: used by contractors to insulate larger areas (e.g., new construction such as walls and roofs, or major renovations).
