"They were a bit over the rest of the company’s that I had out. But the pease of mind that I had knowing that they were going to do it right was worth it. During the bid Mike answered all my questions before I was even able to ask them. Made a great impression on me. They also worked well with me removing my old insulation myself. PLUS , they hauled off the old stuff for me at a great price!! Thx guys!"
"They sent out the owner who did a complementary energy audit - we followed his advice and blew insulation in our attic and wrapped the ductwork. Our energy bills have been reduced dramatically!"
Yes, you should insulate your copper pipes to help regulate their temperature. Well-insulated copper pipes will be protected from freezing and can conserve energy by keeping hot water warm for longer. Foam rubber insulation tubes are the best pipe insulation to prevent freezing since they fit tightly around the pipes while still maintaining some flexibility.
Heat lost through uninsulated basement walls can account for up to 30% of the total energy lost through heat transfer to the outdoors. While homes in mild climates won't gain as much benefit from having an insulated basement as those in cold climates, the effects are still noticeable on your energy bill.
If you’re using faced insulation with paper, face the paper toward the inside of the room during the installation process.
A good way to remember this is that the paper should face the “warm side” as it’s the vapor barrier, meaning it should face toward where the heat will be coming from.
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.
Heavily exceeding building code requirements for insulation not only wastes money on materials but can also lead to ventilation and moisture problems. In most cases, the minimum amount of insulation required by code is perfectly adequate.
