Spray foam is a unique insulation and air sealing product that can be sprayed on site to fit into wall cavities and other small spaces in a house. It limits air infiltration and movement throughout the home, lowering energy bills and making for more comfortable and healthier homes. URL https://assuredinsulationdec.com

The polyurethane used in spray foam is a mix of two liquid chemicals, isocyanates and polyol resin, that react with each other at the point of application to create an insulating foam sealant. The foam expands up to 30-60 times its liquid volume after a spray gun is dispensed, creating a tightly sealed building envelope that can limit heat loss and improve energy efficiency.

The foam also contains a blowing agent, which is usually made of hydrofluorocarbons (HFCs). HFCs are greenhouse gases that contribute to climate change. The HFCs in most spray foam have a global warming potential (GWP) over 3,400, which is thousands of times more potent than carbon dioxide on a per-kilo basis.

HFCs are phased out of use by many manufacturers and spray foam insulation products today include blowing agents with lower GWPs. Using these newer low-GWP blowing agents in home insulation can significantly reduce a household’s contribution to climate change.

All of the building science experts we talked to agreed that if spray foam is used correctly, it is an amazing product that can dramatically reduce heating and cooling costs, increase comfort and make a house healthier. However, they warned homeowners that there are a lot of ways that spray foam can go wrong, which may result in expensive, and sometimes dangerous problems.
