"I had a great experience working with the team from Fairfield Drywall Inc. Sergio and his crew were fantastic to say the least. I have many good things to say about them. Very professional team and great attention to details. They finished the project on time. More importantly they were very considerate of my little kid’s nap time in the afternoon. I made a small request about some changes to the door trim. Sergio was very happy to address my request. Their quote was pretty reasonable and they used the best materials for the job. ⭐️⭐️⭐️⭐️⭐️"

Drywall Insulation questions, answered by experts

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.

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.

Insulating a stone house is an expensive and involved process because it requires building a double-walled house. The walls don’t need to be the same thickness, but they both need to be thick enough to handle any structural demands and meet fire and safety standards. The insulation (usually foam or fiberglass) is then installed between the two stone walls.

You should not put fiberglass insulation in basements, since fiberglass is known to trap mold and mold is more commonly grown and produced in basements. You should also avoid placing insulation near water heaters, oil burners, or other hot appliances. For more information about the best and worst places to install insulation, consider hiring an insulation professional.

You don’t need to staple insulation, as your drywall and studs will hold it into place. But if you already have a staple gun and staples lying around, it can help keep the product in place and avoid any shifting. But, most experts agree it’s an unnecessary step.

If you’re adding a vapor barrier, you will need to staple that in place.
