Insulation questions, answered by experts

There are two places where you should not place foam insulation: around electrical boxes or near lightboxes. The foam insulation could get inside the electrical boxes and damage the wiring. Spraying foam too close to a lightbox creates a potential fire hazard; it could also cause damage to the light.

It depends on your needs and preferences, though many homeowners think it is worth it. Not only is blown-in insulation easy to install, but it is highly efficient with thermal regulation. Most types are mold-resistant, flame-resistant, insect-resistant, and, most importantly, completely safe.

Mineral wool wraps are the most affordable and effective insulation for crawl space ducts. They are easy to cut, last for a long time, and healthier for humans. Meanwhile, fiberglass wraps are cheaper but more hazardous and difficult to handle. If you do choose to use a fiberglass wrap, make sure you are wearing long sleeves and wear proper protective gear.

Insulating your basement walls offers numerous advantages that make the project well worth it. By adding insulation, you can reduce the chances of moisture damage to the house's structure and lower the odds of mold growth. You'll also add comfort to the space by reducing temperature swings and increasing your home's energy efficiency, potentially reducing your energy bills to earn your investment back.

Hanging a thick blanket over your windows will help to keep the heat inside, but only a little. Covering the glass will also prevent the sunlight from getting in, which might actually decrease the efficiency of your window overall. If you get to the point where you’re hanging blankets over your window to keep warm, call in an expert to seal around your windows to prevent warm air from escaping. They may also recommend replacing old windows that aren’t as insulative as newer window technology. Sealing a window isn’t terribly expensive and can make a big difference.
