Insulation questions, answered by experts

The most energy-efficient windows are double—or triple-pane windows with low-emissivity (Low-E) coatings and gas fills between the panes. These windows reduce heat transfer, prevent drafts, and help maintain a consistent indoor temperature. But if replacing windows isn’t in your budget, pairing your existing windows with insulating window treatments can still make a noticeable difference in home comfort and monthly bills. 

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. 

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.

A DIY blown-in insulation project in a typical attic should take you no more than a week to complete. Experienced homeowners can blow an entire attic in one or two days.

Interior walls don't require insulation. However, there are a couple of reasons you may consider adding it in some situations. Insulation in interior walls is excellent for sound-dampening between rooms and can help maintain a regulated temperature in insulated rooms by lowering the heat transfer between adjacent areas of the home.
