What You Need to Know About Spray Foam Insulation

Homeowners can enjoy up to 15 percent savings on heating and cooling costs if their homes are completely air-sealed. Air sealing is the process of eliminating air leaks throughout a house’s envelope (i.e., the shell of the building which consists of the outer walls, doors, and windows) by insulating the areas where indoor and outdoor air can pass through.

To enjoy this benefit, residential spray foam insulation must be present in your Minnesota home. Why spray foam? It has many benefits to offer, plus it is more effective at air sealing.

Read on to learn more about spray foam insulation.

What Is Spray Foam Insulation?

Spray foam insulation is made from polyurethane and isocyanate. These liquids react very quickly once they are mixed and sprayed into place. Once deployed from the sprayer, the foam rapidly expands and immediately takes shape as wall, floor, and ceiling insulation.

Spray foam expands by as much as 100 times its initial volume. The best thing about it is that before it hardens completely, the foam fills every tiny crevice in its path. The building envelope essentially becomes a mold for the semi-liquid polyurethane. This is how you can achieve 100 percent air sealing with spray foam insulation.

How does spray foam insulation work?

At Lange Spray Foam, our highly trained spray foam specialists spray the foam directly into the walls, floors, and ceilings in your home. Spray foam requires a curing period of at least 24-hours.

Although extremely rare, there may be instances where we may recommend that you and your family stay in a hotel or at another residence while we install this insulation. Usually with most installations the home owner is on site.

How is it different from traditional insulation?

Spray foam deviates from the traditional method of insulating homes, from the material to the way it is installed.

Types of Spray Foam Insulation

There are two types of spray insulation:

  • Open-Cell – Less dense with a sponge-like texture. Has a lower R-Value per inch compared to closed-cell. It is mostly used as interior insulation for houses.
  • Closed-Cell – More dense with a smoother texture. It has a higher R-Value and is used in both residential and commercial buildings.

Lange Spray Foam offers both kinds of spray foam insulation. If you want to know more about the differences between the two, get in touch and we’d be happy to explain further.

The Benefits of Spray Foam Insulation

Why use spray foam insulation and not fiberglass, mineral wool, or other forms of insulating material? Take a look at this list of benefits for spray foam insulation:

  • It makes the indoor temperature feel comfortable
  • It lowers utility costs. With heat unable to pass through spray foam insulation, your thermostat will be stable the entire time. There will be no sudden fluctuations in your electric consumption that bring your bills up.
  • There will be less pollen, allergens, and dirt that will enter your home.
  • Your home will have better acoustics: you’ll hear less noise from outside, and loud noises from inside your house (e.g., when you’re watching television or listening to music) will be less disturbing to your neighbors.
