How Do We Do Foam Injection Insulation?
Our technicians will drill a small hole in the interior or exterior wall and fill the cavity with a non-expanding foam that enters the wall with the consistency of shaving cream. When the foam hardens, it creates a seal that prevents any air from entering or leaving the wall. In addition to creating and air seal, our injection foam has an amazing R-value of 4.1 per inch! The energy savings and added comfort are noticeable immediately.
As an added bonus, green spray foam insulation injection reduces up to 80% of outside noise! If you live in a home without insulation in the walls, or walls that are under insulated, call GreenHome today!
Polyurethane Foam Spray
Polyurethane Foam is an expanding spray foam insulation that acts as an efficient air seal in a home or commercial building. Polyurethane Foam provides two to three times the R-value of other insulations, and doesn?t lose its R-value over time, making it perfect in situations where there is little space or a need for major insulation. The foam comes in both open cell and closed cell forms. Closed cell foam has a higher R-value and open cell foam is more flexible. Polyurethane Foam acts as a sound barrier as well, blocking out extraneous noise from your house or building. The foam is commonly used in home remodels, or in buildings with steel walls, and can be easily applied to about any cavity due to its liquid nature when it is initially sprayed, and then expands to fill the cavity. It is lightweight, will not cause ceilings to sag, and provides air-tight insulation. It is also water vapor permeable and flame retardant. At inexpensive rates with rebates available, it is a cost effective way to insulate.
Density of Injected Foam Insulation
Polyurethane foam in open cell form is less dense than its closed cell counterpart. Open cell polyurethane foam has tiny holes throughout the material, trapping air similar to a sponge. Because of these openings, the density is around half a pound per cubic foot to three quarters a pound per square foot. It is much more flexible, feeling similar to packaging material. Closed cell foam has small bubbles of gas trapped inside, instead of holes. It is much denser, being around 2 pounds per cubic foot, and is much stiffer.GET A QUOTE
