"David and his team were very professional and the work they did was excellent---we could tell the difference the next day. The temperature on the 2nd floor is several degree lower than before due to the new insulation and feels much more comfortable. David has solid knowledge regarding insulation and he explains things clearly. Definitely would recommend David and Prudent Homes to my friends and neighbors."

"Comfenergy was very professional thorough from the in-person estimate thru installation. Even though we didnt have a full energy audit, they still go over your entire home and tell you what should and what needs to be done. Some of the little things we did ourselves, or had our handyman. Then Comfenergy did the big part, seal and insulate the attic. We still had late 80's insulation and never a sealing done. It ended up being over an 8 hour project. They were not the cheapest estimate, but definitely the most in-depth review and recommendations provided. The two man team that did the actual work were very professional, showed us the work as the progressed, and good clean up job after all was done."

"After my call to Discount Energy Services, I knew who was coming and when to evaluate my attic insulation. The estimate was prepared on-site with pricing. The workers arrived and knew exactly what they were to accomplish, which they confirmed with me. They prepared the entire path with clean drop cloths and created a plastic drape around my attic stairs. The foreman was glad to explain any aspect of the procedure. My attic was upgraded to R-49 and the difference is notable."

"I am very pleased with how my attic insulation project turned out. when the company came to my house to give an estimate they evaluated my current insulation, told me what I needed to bring my home up to the current standards for attic insulation. (r49) more importantley they told me what I didn't need. I highly recommend this company for your insulation project."

"The company did a good job replacing old insulation in our attic. There was a communication hick-up but the project manager we worked with - Jamie - was able to correct and resolve the issue."

"Louis and his partner we very professional and thorough. They initially put down drop cloths to protect our floors and nearby items. The precisely installed the insulation to match up with what was already on the walls. I had 1 area that we could not clear out completely due to some heavy shelving, and they worked around the shelving and still did a great job. They ensured the new insulation was mounted correctly and attached well with the insulation that was already on the wall. They also fixed up with tape some adjacent pieces of insulation to make it look much neater. When they were finished to thoroughly cleaned up where they had performed the work. I am very satisfied with their work, They did a great job. Thank you"

"These guys were great. Allen met me at the door with a firm handshake told me what they were about to do and if I had any questions just ask. Leo was just as professional during insulation and got the job done in 3 hours. Dylan kept me up to speed during both projects and was very helpful. Easy reccomendation."

Insulation questions, answered by experts

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

Traditional clapboard siding, particularly with panels made from wood, is not a significant insulator on its own. However, you can keep your home cooler in summer and warmer with "insulated clapboard siding," which is a type of vinyl clapboard siding with a built-in foam insulation. Consult a local siding contractor to determine whether insulated siding is right for your home.

There are many reasons one bedroom may be hotter than the rest of the house. The sun will quickly heat a south-facing bedroom with a large window, especially if it lacks quality curtains. If the room has poor insulation, this could let more warm outside air in. Upstairs bedrooms are often hotter than ground-floor rooms because heat rises. Finally, rooms further away from the air conditioning unit may heat up a lot if the system is not properly balanced.

You can purchase bags of cellulose and loose-fill fiberglass blown-in insulation from the same local home improvement store where you rent your blower. If you want to use rock wool insulation, you may need to special order it.

You do not need to drywall over most types of garage insulation. However, doing so can increase noise reduction, make the space more attractive, and keep children and pets from touching harmful fiberglass insulation. If you’re using cellulose or some other type of blown-in insulation (fiberglass and mineral wool are common), you will need drywall to contain the insulation material.
