Insulation questions, answered by experts

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.

While the answer may depend on who you ask, most contractors would agree that spray foam insulation is a strong candidate for this job as it is effective at repelling moisture and is resistant to biological growth.

While carpet over carpet may provide some additional insulation and soundproofing benefits, it's not as effective as other methods. Layering carpets can add a modest buffer against noise and temperature fluctuations, but it's limited compared to installing thicker carpet padding or using specialized soundproofing materials. For optimal floor insulation and soundproofing, consider alternative solutions tailored to your specific needs and budget, such as adding additional padding or soundproofing underlayments beneath the carpet.

As long as your existing insulation isn’t compromised, you can add new insulation directly over them. Inspect your insulation thoroughly and make any minor repairs. Then, add new insulation on top of it. You must be completely certain that there is no contamination or mold growth before doing so. That said, when unsure, consider removing old insulation and lay down fresh ones.

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.
