Insulation questions, answered by experts

Just how long insulation lasts depends on the type of insulation you use. Fiberglass can last between 80 and 100 years, but it's important to start checking fiberglass insulation around the 15-year mark. Spray foam also has a long life span of up to 80 years, while mineral wool can last up to 100 years. Although eco-friendly, cellulose only has a lifespan of 20 to 30 years.

DIY is possible for basic rolls or batts, but professional installation ensures even coverage and efficiency.

Spray foam insulation can last up to 80 to 100 years, making your investment worthwhile over the long run. Closed-cell spray foam tends to have the highest durability. Open-cell foam is subject to moisture, which can lead to deterioration. Remember that some spray foams will damage plastic piping, so consult a pro if you have PVC or CPVC pipes.

Yes, insulating hot water pipes helps your system run more efficiently. This is especially true in basements in colder climates, where cold air likes to settle in. There are a few ways to insulate water pipes (foam is common) to keep hot water hot, reducing the need for your water heater to constantly heat the water in the tank or your circulator to kick on more than necessary.

If you need to insulate behind finished walls, the best option will likely be to have an insulation professional install blown-in insulation. The installation requires small holes cut in your wall, after which the installer can blow loose-fill insulation into the void. After the installation, you’ll have minor drywall patching, which shouldn’t cost more than $100. Compared to ripping down the existing drywall, using a different type of insulation, and replacing and finishing the drywall, this should save you hundreds or even thousands, depending on the size of the room you’re insulating.
