Spray foam insulation - Cupertino, CA

Spray foam insulation is a spray-applied plastic that is commonly used to insulate buildings and as wall insulation to fill and seal cracks, making the building more energy efficient and thus more comfortable inside. It's mainly used for the construction of new homes, but can still be used for existing homes. With spray foam, you can save up to 40% of your energy bill!

This type of insulation offers an effective solution in reducing unwanted air infiltration through seams and has good resistance against heat transfer. This means they're perfect materials when you're trying not only stop drafts but also keep out moisture.

There are three types, which generally fall under closed cell and open cell insulation:

High density - which is used for exterior walls and roofs.
Medium density - which is used mainly for interior walls, non-vented attics, and filling cavities.
Low density - also used for interior walls, non-vented, attics, and wall cavities.

This is a difficult question to answer because the costs vary widely depending on several factors. Compared to batt or fiberglass insulation it can be 2x or 3x the cost. When we estimate the cost of spray foam for your property, the factors we consider include:

- The amount of material needed
- The type of material being used
- The size of the property, the location, and the time required to do the job
- Any additional prep work needed

To give you some numbers to wrap your head around, open cell spray foam may estimate from $0.25 to $1.00 per board foot. Closed cell spray foam may range from $0.50 to $2.00.
