Insulation improves the comfort and energy efficiency of properties. It prevents outdoor air and humidity from entering a space, which keeps the HVAC system working overtime to cool and heat your home or business. Spray foam insulation is popular among contractors because of its ability to act as a barrier to both air and heat. Here’s more information about this material and its benefits.

A Brief Guide to Spray Foam Insulation

What is it?

Spray foam insulation uses a combination of two methylene liquids. When they make contact with the gas in the sprayer, they emerge as a polyurethane foam that expands to fill gaps and cover surfaces thoroughly. It differs from traditional insulation because it blocks airflow in addition to preventing heat transfer. 

What are the different types?

Open-cell foam insulation is made from particles that fill with air when sprayed, giving the material a soft and flexible structure. Its durable fiberglass and cellulose composition reduces the ability for air and heat transfer, keeping indoor temperatures comfortable.

Closed-cell insulation produces a more rigid foam structure with higher density. When it combines with the insulating gas, or blowing agent, it produces smaller cells that bind tightly together to block out moisture, air, and heat.

Where should a contractor apply it?

Spray foam insulation functions well for sealing gaps, holes, and cracks in walls, ceilings, and floors. Open-cell is ideal for attics since it does not protect against moisture. This allows you to see roof leaks and repair issues before they cause mold buildup and rotting lumber. Closed-cell works well in basements and crawlspaces because it keeps humidity from diminishing air quality and damaging furniture. 

Does spray foam deteriorate over time?

With proper application, foam insulation will last up to 80 years, and in some cases, as long as a structure lasts. A contractor must mix the liquids at the correct temperature and allow the chemicals to off-gas for up to 72 hours. Spray foam must remain undisturbed and out of direct sunlight to keep the material intact and prevent cells from breaking down.
