Insulation questions, answered by experts

When looking for a company who installs insulation, your best bet is usually to work with an insulation contractor or professional insulation company. If you can't find a local insulation company, working with a general contractor can be another option. No matter who you hire, always confirm that they have experience.

It improves energy efficiency, reduces noise, enhances indoor comfort, and prevents drafts by filling wall cavities.

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.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

Unfaced wall insulation is easier to cut and install, making it the better choice for a DIY project. It’s also more affordable. But if it’s unfaced, you’ll likely need to add a vapor barrier to reach your desired R-value and efficiency, as it doesn’t offer any moisture barrier.

Faced insulation uses paper or foil to create a built-in barrier and doesn’t require an extra step. It’s also more fire-resistant and safe. But it’s quite a bit more expensive and a little bit harder to work with as a DIYer.
