What is Spray Foam Insulation?

Installing spray foam insulation is a much different process than using other materials such as fiberglass or cellulose. It begins as a liquid made up of isocyanate and polyol resin, which, when combined, react to form polyurethane and expand up to 30-60 times their original volume as a liquid. When it is used in home insulation, the “spray” application is particularly useful for insulating even the hardest-to-reach spaces in a home, since it is applied wet and expands into a thick foam, fitting snugly in wall cavities, crevices and gaps.

Benefits of Spray Foam Insulation in Gilroy

When deciding on the type of insulation to use in the construction of your new home or commercial property in Gilroy, there are a number of benefits of spray foam to consider. Spray foam insulation is typically made from polyurethane, which is a very energy-efficient material that makes a huge difference in keeping the warm air out during spring and summer while keeping the cool air out during fall and winter, reducing your monthly energy costs. Choosing to install spray foam insulation can also help to:

  • Save money on your energy bill
  • Improve your indoor air quality
  • Create a more environmentally friendly space
  • Increase your HVAC system’s efficiency
  • Reduce noise levels
  • Prevent air and moisture infiltration

What R-Value Does Spray Foam Insulation Have?

Different insulation materials are assigned what is known as an “R-value.” The R-value of an insulation material refers to the capacity of that material to effectively resist the transfer of heat. A higher R-value demonstrates a greater ability for a material to insulate a space. The R-value of spray foam insulation is typically around 6.5 per inch, which is among the highest of any type of insulation. Spray foam has almost twice the insulation ability as materials like fiberglass and cellulose which range from 3 to 4 per inch. This higher level of insulation is noticeable after being installed, and helps to keep your home cool in the summer and warm in the winter.
