spray foam is a versatile insulation and sealant that adds R-value (resistance to heat flow) to the walls of new homes or buildings. It’s sprayed as a liquid, which expands to fill the nooks and crannies of a wall or other surface. It’s very effective in making houses airtight, which improves energy efficiency and comfort.
But it’s not without its drawbacks, especially from a sustainability perspective. It’s made from petroleum and a mixture of toxic chemicals, some of which emit unpleasant fumes during installation. This can make the home uncomfortable for its occupants and can even lead to health problems in extreme cases. It is also difficult to reclaim or recycle, and almost all spray foam ends up in landfills.

It’s usually sprayed on wood framed walls during new construction. This means the wood studs spend weeks or even months standing in the rain getting saturated with moisture before exterior weather barriers and the roof cover protect them from the elements. That moisture makes them swell and shrink as they dry, which causes them to crack or break if they come into contact with something solid such as a nail. And spray foam can’t be removed easily to work on plumbing or wiring behind it.
And of course, it’s sprayed with hydrofluorocarbons (HFCs) which are powerful greenhouse gases that can be hundreds or thousands of times more potent than carbon dioxide. Fortunately, there are low-GWP alternatives being used in place of HFCs for polyurethane spray foam.
