Spray Foam Insulation San Jose

Spray foam insulation has been one of the most popular types of insulation for homes due to its immediate and long-term benefits. Spray foam insulation is a two-part liquid insulation material that insulates and air seals your home. The material-- an iso and a resin, comes in two large 55-gallon drums. These liquids are kept separate until used at the site by a professional licensed spray foam installer. These two liquids go up through a heated hose to the spray gun, where they combine to create the foam.

Why insulate with Spray Foam CA?

  • Seals clean air in and keeps moisture out
  • Prevents dust, mold, pollen, and other pollutants from entering your home
  • Air conditioners and furnaces run less and last longer
  • The most efficient insulation
  • More comfortable
  • Environmentally friendly

Save on Utility Bills

You are throwing money out the window when you live in a home that is not correctly insulated. Air can leak in and out through openings and cracks in your property's structure. Spray Foam Insulation San Jose prevents wasteful air exchange.

Once foam insulation is sprayed, it expands and seals the area being insulated. Your home will stay cool in summer, warm in winter, and at the same time, you save up to 50% on your utility bills. Because your air conditioner and furnace do not have to work hard; therefore, they will cost less to operate and last years longer.

A Healthier and More Comfortable Home

Spray Foam Insulation keeps your room temperatures constant and comfortable as it gets rid of drafts and cold spots. Its air-tight vapor barrier prevents moisture, mold, and mildew from coming inside your home. Spray foam insulation expands to fill all gaps and becomes rigid when dried, which reduces the amount of pollen, dust, and pollutant from coming inside your home. Lastly, it works as a barrier, keeping outside noise, rodents, and insects outside your home.

There are two types of spray foam insulation using roofing foam in constructions: open-cell and closed-cell spray foam.

Open-cell Spray Foam Insulation

Open-cell spray foam insulation is a soft, low-density material that is typically used for interior applications like wall cavities, attics, basement walls, the underside of roof decks, and crawl spaces. This foam insulation's open-cell structure allows for moisture permeability to help contribute to the wall assembly's moisture management and bi-directional drying.


  • Allows for bi-directional drying
  • Can accommodate long-term creep and seasonal movement
  • Can be installed at an affordable price and target the same specified R-value*
  • It is not considered a food source for mold
  • Provides sound dampening qualities
  • Lower installed cost, per square foot

Closed-Cell Spray Foam Insulation

Closed-cell spray foam insulation is a rigid medium-density material used in exterior use like continuous insulation applications and interior applications. This foam insulation has a high R-value per inch, making it suitable for small areas that need the highest possible R-value to comply with the building code requirements. Closed-cell spray foam is recognized as flood-resistant material due to its rigidity that helps reject a bulk of water.


  • Ability to reject bulk water
  • It can be applied at very low temperatures as low as 5°F
  • Adds wall racking strength and impact resistance
  • Easier to accommodate high R-value
  • Lower vapor permeance
  • Higher tensile and bond strength

Homeowners should consider the benefits of spray foam insulation, whether their home building is new or old. Even though it is more expensive than other insulation types, it can help you save money on your energy costs. It protects your home from cold and moisture during winter and protects it from the heat in summer. You will enjoy your privacy as it blocks noise better compared to other types of insulation.
