Insulation questions, answered by experts

Cellulose insulation is usually made from recycled paper products, such as old newspapers, but cellulose might also contain recycled denim. While most homeowners traditionally buy cellulose insulation to use for installation, it is possible to make your own at home with old newspapers, cardboard, a paper shredder, and boric acid (important for fireproofing your cellulose insulation materials).

Spray foam insulation can last between 80 and 100 years, depending on the type. Closed-cell spray foam is more durable, while open-cell foam is more susceptible to moisture damage and deterioration. It's important to consult a professional installer to understand which type of foam will be used and its specific longevity. Additionally, be aware that some spray foams can damage plastic piping, so if you have PVC or CPVC pipes, discuss this with your installer.

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.

According to a report from Energy.gov, radiant barrier installations can save between 5% and 10% on your energy bill each month that your HVAC cooling is in operation. That fact can mean savings of up to more than $325 per year for homes that experience frequent direct sunlight and high summer temperatures. 

The best R-value for home insulation depends on where you live and where you’re installing the insulation. Your climate zone plays the biggest role in determining the correct R-value, so be sure to know which zone you live in when determining the R-value you need.
