Drywall Insulation questions, answered by experts

2x4 walls can hold R-13 or R-15 batts of insulation, which is usually about 3.5 inches thick. You should also check with your local building codes to see if there’s a required thickness you need to adhere to. 

You can also use R-value maps to determine the best thickness and ratings for where you live. For example, someone in Texas doesn’t need as thick of insulation as someone in Montana. Energy Star has a good one you can reference.

Every exterior wall in a house should have insulation. Municipalities require that new construction homes come with adequate insulation to handle the local climate. The state or local building code lays out the minimum insulation requirements. Interior walls seldom have insulation. Exceptions include interior wall insulation for sound dampening or temperature control of specific rooms.

Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.

Single-pane windows might let in the cold, but if you’re not ready for a long-term solution or window replacement, there are quick fixes to keep your space warmer. Start by sealing gaps with weatherstripping or caulking around the frame to block drafts. For an extra barrier, apply window insulation film to the glass, trapping an air pocket between the film and the window. Thick curtains or thermal drapes can also help keep the chill at bay. And if you’re in a pinch and looking to get creative, bubble wrap can provide a surprisingly effective layer of insulation—just spritz the window with water and press it on, bubble side in.

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.
