Insulation questions, answered by experts

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.

Yes, there are government incentives available in some regions for insulating air ducts as part of energy-efficient upgrades. These incentives aim to encourage homeowners and businesses to improve energy efficiency and reduce their carbon footprint. To determine whether you qualify for such incentives, check with your local utility company or government agencies. They often offer rebates, tax credits, or other financial incentives that can help offset the cost of duct insulation projects.

Selling a house with spray foam insulation can be challenging due to concerns about improper installation or its compatibility with the home's structure. If not applied correctly, spray foam can cause issues such as moisture buildup, cracking, or damage to wiring and plumbing. If the insulation didn't cure correctly, there are also flammability concerns. Removing or repairing this type of insulation can pose risks as well.

The lifespan of crawl space insulation depends on how well you maintain your insulation and the type of insulation. Fiberglass will need replacing every 15 to 20 years on average if you don't have a vapor barrier in place. If you do have vapor barriers in place, then your insulation could last much longer. Spray foam insulation can last anywhere from 80 to 100 years. 

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.
