Insulation questions, answered by experts

It is possible to insulate your walls without removing drywall, but it’s not a good idea to attempt the work yourself. A professional can use blown-in insulation or spray foam insulation to fill wall voids without opening up the walls, and the option they use typically depends on your climate and whether or not there’s insulation in your wall already that can remain in place. Spray foam insulation costs more and isn’t always a viable option, but it’s a better insulator. Call in an expert to help decide which is right for you.

Choose affordable materials for a cost-effective insulation installation (say that five times fast). The most affordable insulation for your garage is fiberglass. Fiberglass comes in batts or rolls and is relatively easy to install compared to other types of insulation. You can also install this insulation without needing to drywall over it, which can cut down costs.

For your safety, you should always wear a mask when cutting batts of fiberglass insulation. We also recommend wearing eye protection, safety gloves, and long sleeves to protect your skin. Properly suiting up helps you avoid several fiberglass issues, such as cuts from the tiny shards of glass and inhaling small bits of fiberglass.

When it comes to window coverings, cellular shades are typically known as the most energy-efficient option. Cellular shades are also known as honeycomb shades. They are made of a soft fabric and take the form of “honeycomb” cells. These cell pockets trap air in and around your windows, providing insulation.

Yes, energy-efficient homes are increasingly desirable in the market.
