"We had insulation installed a week earlier by Koala. During the insulation, Jasper (insulator) suggested another area that we might consider installing blown-in insulation. We agreed and the second job was performed on Friday, the 24th. Jasper and Richard were on time, the insulation project was well done and they left the area very clean. Would use them again."

"Great! Job was complete .... removal of existing 50+ year old insulation, air sealing attic, baffle installation, installed 18 inches new fiberglass blown insulation, and new whole-house fan. Job started and completed as proposed. Crew on-time, quietly performed their work, and left spaces clean when done. Definitely worth the cost as noticeable improvement in second floor temperature and humidity readings."
Owens Corning ProPink R-49 Blown-In Insulation. Our most popular product
These vents help your attic circulate air. With attics reaching over 120 degrees in the summer these are very important. They prevent mold and increase the lifetime of your insulation. Most other contractors miss installing these.
Look at the difference! Our foam is fire-rated which allows us to air seal around penetrations that contractors never could before.
Most homes have penetrations all over there attic. Imagine trying to blow up a balloon with a bunch of holes. It will never fill up. Now imagine trying to blow up your house with air conditioning and heating with a bunch of holes in the attic. It will never fill up.
Recessed can lights are notorious for leaking air. Recessed can light covers help with air-sealing your living space and prevent fires.

"Our first interaction with Atlas was with Shannon. As knowledgeable and personable as one could hope for. She clearly explained cost effective measures to better insulate our house. We opted for sealing and insulating our attic and weather stripping a number of doors. We were very pleased with the workmanship and the energy savings they produced. They also helped us get a PEPCO credit which reduced the overall cost of the job. A winner!"

Insulation questions, answered by experts

Unfortunately, pipes can freeze when exposed to prolonged freezing temperatures, whether or not you have installed insulation covers. Insulation covers, however, are still an excellent idea as they can reduce the chance of your pipe freezing by keeping the pipes closer to the temperature of the water inside the pipe.

If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.

Yes, it is possible to have too much insulation, which can have detrimental effects. While more insulation might seem better for energy efficiency, a home needs to "breathe" or ventilate to release moisture that accumulates inside. Over-insulating can seal a house too tightly, trapping water vapor and leading to several problems, including mold, mildew, and condensation. Homes in warm, humid climates are particularly susceptible to mold, while those in colder climates can experience condensation from temperature fluctuations. Additionally, adding more insulation than the recommended amount for your climate may not provide recoverable energy savings. To avoid these issues, consult a professional insulation contractor who can determine the optimal amount of insulation for your home.

Buying a house with vermiculite insulation is not recommended without going through a proper testing process. Vermiculite insulation can potentially contain asbestos, which poses health risks when disturbed. While it is possible to purchase a home with vermiculite insulation, you should have it tested for asbestos, and ensure proper containment if asbestos is present. If asbestos is present, you will want to hire a professional to remove it, ideally before you move in.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.
