"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."

"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

Most insulation lasts 15 to 20 years, but it really depends on the type of insulation. Spray foam is a permanent insulation material that can last up to 100 years. Fiberglass and cellulose typically settle, shift, or deteriorate around 15 years. Once your insulation reaches the 15-year mark, it's time to check it for signs of needing to be replaced.

Garden blankets and frost cloths are the best things to use to protect trees and plants from frost. They are made from polypropylene fabric, which is lightweight, breathable, and dries fast. If you can’t get garden blankets or frost cloths before the freeze, you should use lightweight blankets, sheets, or towels.

Cellular shades, also known as honeycomb shades, are the most energy-efficient and insulating window treatments. Their honeycomb structure is made of soft fabric that forms layered cell pockets. These pockets trap air, creating a thermal barrier that reduces heat loss in the winter and blocks heat gain in the summer. For even greater insulation, consider double- or triple-cell varieties. Side-tracked cellular shades, which seal the edges of the window frame, can further minimize air leaks and maximize energy efficiency.

Selling a house with spray foam insulation can be challenging due to concerns about improper installation or its compatibility with the home's structure. If not applied correctly, spray foam can cause issues such as moisture buildup, cracking, or damage to wiring and plumbing. If the insulation didn't cure correctly, there are also flammability concerns. Removing or repairing this type of insulation can pose risks as well.

Spray foam insulation doesn’t do well around heat sources. Therefore, You can use spray foam insulation to seal around HVAC boots that penetrate through the drywalls or around where wrapped ducts connect to the boots, but we don’t recommend using spray foam insulation to encapsulate your air ducts. Spray foam insulation on air ducts is also less effective compared to duct wraps.
