"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."

"Atlas Home Energy Solution performed an energy audit for my home, followed by various insulation and weather-proofing tasks. Three other companies gave me estimates much higher for a work smaller in scope. Atlas estimate was lower for a more extensive work, and when combined with the rebate from BGE, turned out to be a highly reasonable deal. The employees were pleasant, courteous, and performed every task to perfection. I highly recommend them for any home energy issues"

Insulation questions, answered by experts

While a few icicles on your roof are standard, a large accumulation can be a sign of a bigger problem, such as poor insulation. This is particularly true if you are also dealing with ice dams. If you have numerous large icicles, it is recommended to have a roofing contractor diagnose potential insulation issues and create a plan to solve them.

Depending on where you live and the conditions of your basement, you may not need to insulate your basement. Your best bet is to talk to a basement remodeling company to find out what they recommend doing.

Insulating your basement can help improve your home's energy efficiency, but it will also increase the cost of your basement remodel project. The average cost of installing basement insulation is $2,400.

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.

Canned spray foam has an R-value of R-3.7 per inch. However, it’s not great for use as insulation. Also known as single-component spray foam, it doesn’t expand as much as two-part types that work for insulating the whole house. Save the canned foam for gaps around doors and windows.

Each of the three types of wool insulation has particular disadvantages. While their R-value is higher, they all cost more than fiberglass versions. Installing mineral wool and sheep wool requires protective gear. Because of its vulnerability to insects, chemicals are used in its production. Hemp wool is more costly to install than other types because additional tools and labor are involved.
