What Is Spray Foam Insulation?
Spray foam insulation has taken the home improvement world by storm! Whether you are scrolling through DIY Home Repair Pins on Pinterest or watching your favorite home improvement show on the HGTV network, you are likely to see spray foam insulation on your screen at some point. But what is it exactly? How can it benefit my home or business?
Spray foam insulation is developed from two types of composite materials, polyurethane and isocyanate. When combined, there is a chemical reaction that causes their combined substance to expand and harden. While installing, both materials are simultaneously sprayed, allowing them to expand and form a protective layer of spray foam insulation over the desired area.
A Tale Of Two Foams: Open Cell & Closed Cell
There are two types of spray foam insulation – open-cell and closed-cell. Open-cell spray foam is more dense and is spongy to touch. This gives it an effective sound dampening effect. Open cell is also considered to be more energy efficient.
Closed-cell insulation has cells that are completely closed and has the ability to seal out water. It’s much tougher and more rigid, so it is ideal for outdoor use. With a high R-value, easy installation, and impermeability for water and air, closed cell is a top choice for home and commercial installation.
