Spray foam insulation is a high performance type of insulation that can help you increase home comfort, boost energy efficiency, reduce heating and cooling costs, eliminate drafts, and more. If you’re looking to improve your home with one of the best types of insulation available, spray foam installed by the experts at Green Team LI may be your best bet.

Why Choose Spray Foam Insulation?

Here is a look at just a few of the things that make spray foam an excellent insulation material.

Highly Effective

Spray foam, also known as spray polyurethane foam (SPF), is one of the most effective types of insulation available — with an effectiveness rating (R value) of R6 per inch.

Air Sealing Capabilities

Unlike other insulation materials like fiberglass and cellulose, spray foam expands to fill the space where it is installed. This means it can seal those pesky air leaks throughout your home which waste energy, bring in drafts, and allow pests and moisture to enter. Even if you’re planning to insulate with a different material, it’s a good idea to use spray foam first to seal air leaks.

Moisture Resistant

Spray foam is also moisture resistant, making it a great insulation option for keeping out moisture and preventing mold growth.

Where Is It Best to Install Spray Foam?

The versatility of spray foam makes it a great option for a number of areas within the home, including:


  • Attics & roofs

  • Walls

  • Basements & crawlspaces

  • High moisture areas

  • Areas with air leakage


Green Team LI: Long Island’s Spray Foam Installer

There are two types of spray foam insulation: closed cell and open cell. Closed cell spray foam provides a superior air and moisture barrier and is the most effective type of insulation available for your home. Open cell is a more affordable option that still offers impressive R value and air sealing capabilities. We install both types of spray foam to give Long Island insulation solutions that fit their needs and budget.
