Spray Foam Insulation

Open-cell versus closed-cell foam

Open-cell foam is soft, light and expands a lot, providing good insulation and sound absorption at a lower cost. Closed-cell foam is dense, adds structural rigidity and resists moisture, with a higher R-value per inch. It suits crawlspaces, rim joists and roofs where moisture or limited depth is a concern. A pro chooses the type based on location, climate and building design. Each has different vapor control and fire-protection requirements. Get the key details in writing, including materials, timing and what is and is not included, so everyone is working from the same expectations.

Safety, curing and indoor air quality

Foam is installed by trained crews wearing respirators, and the occupants should leave the house during spraying and for the time recommended by the manufacturer. Proper ratio and temperature are crucial, because off-ratio foam can smell and off-gas. Ventilate the space and follow reentry guidance. Ask for the product data sheet and confirm the crew is certified by the manufacturer. Never allow foam to be sprayed over wiring that is not rated or near heat sources. Mention any earlier repairs or known problems at the property, because that history helps the pro choose the right method.

Code, fire barriers and unvented attics

Spray foam in attics and crawlspaces must usually be covered with an ignition or thermal barrier, and unvented attic assemblies have specific requirements. Local code and energy standards determine thickness. Foam can hide leaks and framing problems, so repair roofing or plumbing issues first. Ask for inspection records and keep the documentation for energy compliance. Removing foam later is difficult, so be sure of your plan. Ask the pro to walk you through the plan before work begins, and to point out anything that could change the scope once the job is open.
