Insulation questions, answered by experts

Avoid sleeping in a house immediately after spray foam insulation is applied due to the off-gassing of volatile organic compounds (VOCs). These fumes can cause respiratory irritation, headaches, and other health issues. It’s recommended to wait 24 to 72 hours after installation to allow the foam to fully cure and the fumes to dissipate. The exact time frame depends on the type of spray foam used and the ventilation during the application, but your installation pro can advise you on the best timeline. 

DIY installation is feasible with the right protective gear and knowledge, but professional installation ensures full coverage and maximum efficiency.

You can insulate an existing garage door. But while it’s a cost-effective option upfront, it may not perform as well as a garage door that comes with insulation. If you live in a colder climate—or if you plan on working in your garage and need a new door—you should purchase one with existing insulation for better efficiency. 

Blown-in insulation works, but only for unfinished attics. Also, it isn’t the longest-lasting nor the most effective option. For better options, look into spray foam insulation or natural fiber batts. They typically have a longer lifespan, better heat resistance, and stronger sound-proof abilities. Spray foam insulation costs about $1.25 to $1.50 per square foot, but can go up to more than $4 per square foot. Fiber batt pricing varies depending on the material.

Canned spray foam has an R-value of R-3.7 per inch. However, it’s not great for use as insulation. Also known as single-component spray foam, it doesn’t expand as much as two-part types that work for insulating the whole house. Save the canned foam for gaps around doors and windows.
