The Ultimate Guide to Spray Foam Insulation: Types, Costs, and Benefits
The Ultimate Guide to Spray Foam Insulation: Types, Costs, and Benefits What is Spray Foam Insulation? Spray foam insulation is a type of insulating material that is sprayed directly onto walls, floors, ceilings, and other surfaces. It expands into a thick foam, sealing cracks, gaps, and hard-to-reach areas. Unlike traditional fiberglass or cellulose insulation, foam insulation provides both a thermal barrier and an air seal. There are two main types of spray foam insulation: open cell and closed cell. Both offer unique benefits depending on your needs and budget. Open Cell vs. Closed Cell Spray Foam Open Cell Spray Foam Open cell spray foam is softer and more flexible. It expands rapidly, making it ideal for hard-to-reach spaces. It's generally cheaper than closed cell spray foam and offers excellent soundproofing. Closed Cell Spray Foam Closed cell spray foam is denser and more rigid. It creates a solid, moisture-resistant barrier that's great for areas prone to dampness....
