Can I put a blanket on the windows to keep the heat in?

• <div><p>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.</p></div>

Q: Does an attic floor need a vapor barrier?

• <div><p>Vapor barriers in attics are a bit outdated and most areas no longer recommend them for attic spaces. For vented attics, the best method is usually to install drywall and cover it with latex paint before attaching insulation fiberglass, cellulose, or foam insulation. When renovating an attic to use as a living space, a contractor can guide you on the best way to cover insulation.</p></div>

Q: Why is my home hotter than outside?

• <div><p>High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home&rsquo;s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).</p></div>

Q: Do I need to air seal my attic before installing insulation?

• <div><p>Air sealing isn't necessary for attic insulation, but it's incredibly helpful since it can help you identify and patch any existing air leaks. Failing to find these leaks before adding insulation can render your insulation less effective, leading to higher energy bills and potentially costly repairs down the line. </p></div>

Q: What is the life expectancy of wool insulation?

• <div><p>Mineral wool has an excellent life expectancy of up to 50 years, provided it's kept dry and free of pests. Compared to fiberglass, with a life span of 20 to 30 years, mineral wool stacks up well for long-term cost savings. Sheep wool maintains a similar life span to fiberglass, while estimates for hemp wool insulation life expectancies are all over the board, ranging anywhere from 20 to 100 years. </p></div>

They were so pleasant and efficient; it also turned out that due to the structure of our home they couldn’t insulate as much as we wanted, but they cut the cost accordingly so that we didn’t have to pay the original quote amount.
