Is Spray Foam Insulation Non-Toxic Once It’s Cured?

September 22, 2024

Attic insulation is an excellent option for homeowners who are looking to upgrade their home’s insulation. It’s durable, energy-efficient, and it can help prevent air leakage which contributes to higher heating and cooling bills. Many questions come up when a homeowner is considering spray foam insulation. Here’s some information that will help you decide whether or not this type of insulation is right for your home.

Spray Foam Insulation Is Non-Toxic Once It’s Cured

Spray polyurethane foam is made of two liquid chemical components that undergo a chemical reaction to create this plastic foam insulation. It is sprayed through a special rig that ensures the foam is mixed and sprayed properly. The rig also keeps the chemicals at the proper temperature to ensure that they expand correctly. After spraying the foam, the chemicals must sit and cure. This takes about a week. During this time, they off-gas. This is why people in the area need to wear full face and respiratory protection.

The foam can be sprayed into tight spaces that cannot be easily reached with other types of insulation such as fiberglass batts or rigid foam. The foam can fill every nook and cranny, which reduces air leakage. The foam has a high R-value, meaning it is an effective insulator. It can be used in attics, basements, walls, and rim joists in new construction or in existing homes. It can even be sprayed on the exterior of wood framing and sheathing when coated with a water-control layer.
