"We badly needed insulation in our attic. We got three quotes. Weather Shield was not only the most reasonable, but the only company in which the owner both gave us the quote and installed the insulation with colleague. We could not have asked for more professionalism or better service. Would highly recommend Gus."

"Very professional and courteous team. Five team members where here for six hours installing, new fan roof vents, removing old duct work including a bird nest, installed new vents between the beams, discovered builder originally did not properly insulate one area above master bath and corrected that area too. Had insulation blown in very deep to R49 and once done with house attic had garage attic also fixed and insulation installed. We have seen a big improvement, bedrooms are so warm now we keep thermostat on 63 or 65 from midnight to 0800 and 65 to 67 during the day. Garage is not freezing anymore and recently with temperatures at 30 to 10 degrees outside the garage is still between 47 to 43 which keeps any garden, household or automotive products from freezing out there which helps with storage of these products. A professional team from evaluation, quotes, installation, office scheduling, payments and follow-up. Highly Recommended. Thank you, Robert USN Retired"

"I met Robert for an estimate. Robert is a straight shooter, gave a competitive estimate, and no pressure at all. I decided to go with him after another estimate I got was borderline gouging. I was impressed with how efficiently and quickly his crew worked. These guys know what they are doing. Many companies can insulate an attic but Attic Air can also replace attic and bathroom fans. Make sure your soffit though has holes in it to let air into the attic. This was an optional piece for me but the crew chief explained to me the new attic fan that was being installed would burn out if there was not enough air coming in from the soffit for the fans to circulate. I also took advantage to replace two other very old bathroom fans with more powerful Panasonic 100 cfm LED fans to take advantage of the crew being in the attic. My second floor used to be 3 degrees cooler than what the thermostat showed on the first floor, but is now 1 degree or no difference. I am hoping I won't need a separate cooler fan in the summer on the second floor. Didn't need a separate heater for winter at least or shiver unless I brought up the temperature on first floor."

"Koala Team was excellent starting with John Anthony giving us a quote immediately after looking at the space. He told us about a rebate and applied it off the top. Team showed up on time, they were neat, did a beautiful job of putting the foam insulation in. We are very happy and would definitely recommend Koala to our friends and neighbors."

"I am very happy with the work done by Green Attic Insulation. David and Charlie were very friendly, professional, responsive, and flexible in working with my changing needs. I originally was looking into insulation but then discovered there was mold in my attic. As the job grew, David, Charlie, and their team worked with me to address the additional parts of the job. I really appreciate their knowledge and the thorough job they did. They took many pictures of their progress and kept me informed each step of the way. Thank you very much!"

Insulation questions, answered by experts

Radiant barriers and insulation serve different purposes, so one is not inherently better than the other. Radiant barriers reflect radiant heat, helping keep spaces cool, especially in hot climates, while insulation slows heat transfer through conduction. For optimal energy efficiency, it’s best to use both together. 

Radiant barriers can enhance the performance of insulation by preventing heat gain in the summer and heat loss in the winter. The choice between them depends on specific climate conditions and the building’s design requirements.

Exposed ductwork can sweat just like ductwork placed behind walls, sometimes even more so. Ductwork sweats—like a cold drink on a hot day—because of a temperature imbalance between the air in the duct and the air in the room. In a crawl space or wall, this temperature can equalize faster due to the small space but in lofts and open rooms, that wouldn’t happen as quickly. Many people insulate their ducts for this reason.

A DIY blown-in insulation project in a typical attic should take you no more than a week to complete. Experienced homeowners can blow an entire attic in one or two days.

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.

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.
