"I RECENTLY HAD MY ATTIC INSULATION REPLACED BY MASTER ATTIC. ALEX CAME OUT RIGHT ON SCHEDULE AND GAVE ME A FAIR PRICE. ( I DID HAVE 4 OTHER ESTIMATES) THE CREW LEAD BY ROBERTO WAS AMAZING. THEY WERE VERY CONSIDERATE, CAREFUL IN MAKING SURE THE AREA WAS SEALED OFF AND WERE VERY CAREFUL OF MY PERSONAL BELONGINGS. THEY DID A GREAT JOB IN REMOVING OLD INSULATION , VACUUMING OUT THE ATTIC ,SPRAYED AREA AND SEALED ANY OPENINGS. BEFORE THEY BROUGHT IN NEW INSULATION, THEY ASKED ME IF I WISHED TO TO VIEW THE ATTIC AND I DID. I WAS AMAZED EVEN AT THIS POINT, HOW CLEANED EVERYTHING LOOKED . (THIS INSULATION HAD BEEN UP THERE FOR 70 YEARS) NEW INSULATION WAS INSTALLED AND IT LOOKS GREAT. THE CREWED CLEANED UP EVERYTHING , EVEN VACUUMED THE AREA IN THE ROOM.

Insulation questions, answered by experts

Yes, you need a 1.5-inch to 2-inch air gap in a cathedral ceiling to allow proper air flow and prevent cathedral ceiling venting problems. This amount of airspace allows warm, moist air to properly leave your ceiling to avoid moisture build-up and other issues that put your home at risk. You can also add an air vent for extra air flow.

It improves energy efficiency, reduces noise, enhances indoor comfort, and prevents drafts by filling wall cavities.

The best time to insulate a garage ceiling is when the weather is mild and dry. That means it shouldn’t be stormy, snowy, or raining, and the temperatures should be comfortable. Ideally, you’ll insulate your garage ceiling in the fall, before winter hits. Not only will you be the most comfortable, but you’ll also likely see the greatest energy savings heading into the colder weather with a newly insulated garage.

Although the cost might seem high, winterizing your home is important for your health and the structural integrity of your home. Winterizing will keep your home warm and toasty during the cold months and prolong the life of your appliances, windows, pipes, sprinkler system, pool, and more. 

Glass fibers are often used in HEPA filters because of their high efficiency, durability, and thermal stability. Some HEPA filters are made with synthetic fibers, but they may not be as effective. While there is some fiberglass shedding, as long as the HEPA filter is intact and not cut open, the amount of fiberglass released by a HEPA filter is well below the breathable particulate matter.
