TYPES OF INSULATION
Once you’ve determined where you are leaking heat, you can patch up your insulation in a number of different ways. The location of the leaks will determine which type best suits your needs, but whatever you do, it’s a good idea to hire an expert to help you determine what type of insulation is best for your climate and where to put it. For attics and roofs I prefer blown-in cellulose insulation, which is basically shredded/recycled newspaper. When adding additional insulation to your walls, my favorite type of insulation is a soy-based spray foam called BioBased. While I like the organic and eco-conscious qualities of Bonded Logic recycled denim insulation and wool insulation, I find that when you are looking for the highest R-value and the tightest seal, spray foam just can’t be beat, and BioBased is my favorite green option in that department.
DON’T FORGET WINDOWS
As much as 25% of a home’s heat is lost through its windows, so when replacing windows get the most energy-efficient model you can afford. If you have old single-pane windows and you live anywhere where it gets cold, you need to replace those windows pronto with double-pane glass. If you have really large windows and live in a cold climate, it also might be worth considering super-insulated windows with triple panes, argon in between panes, and really tight seals around the edges. Or, if you want to take it to the next level, Marvin Windows now makes a triple pane with a krypton/argon/air gas mix in between the panes, this window ups the thermal performance by 0.03 beyond the U-factors of a tripane with argon, which Marvin also offers.
