What is Drywall – Sheetrock – Gypsum?
Drywall–also known as sheetrock–is a panel made of dihydrous calcium sulfate (gypsum) pressed between two thick layers of paper. It consists of a gypsum core covered either by paper or fiberglass.
Gypsum is hydrous calcium sulfate – CaSO4.2H2O. Each molecule is composed of two molecules of water (H20) and one of calcium sulfate (CaSo4). Gypsum contains large amounts of water bound in crystalline form. 10 square feet of gypsum board contains over 2 quarts of water.
What is Greenboard Drywall?
Greenboard drywall has a moisture-resistant paper skin and a treated core. Greenboard is a form of drywall. It differs from regular drywall in two ways:
1) Greenboard drywall has water-resistant paper covering on one side;
2) The paper covering is green, thus the name “greenboard”.
The gypsum material sandwiched between two paper coverings is same.
Greenboard Drywall Cannot Be Used For Wet Applications
Although the paper covering of greenboard drywall is water-resistant, it is not waterproof. Also, the brittle gypsum core is not suitable for wet or damp locations like basements. Using greenboard drywall in a wet location is just not the right decision.
Should You Be Concerned About Mold?
YES. Mold is a potential health hazard in buildings and homes and it requires special care to clean it up or avoid its formation in the first place. Along with asbestos, lead and PCB’s, mold can also cause costly mechanical and structural damage.
Should You Use Fiberglass Insulation in a Basement?
Absolutely not. You should not use fiberglass insulation in basements. First, you need to know what is insulation? Insulation is a simple and effective tool to increase the comfort and cost efficiency of the basement of your home. There are various wall insulation types but the most common is a blanket made of fiberglass that comes in rolls or batts.
Experts have recommended against using fiberglass batts or blanket insulation in basements. The traditional method of installing fiberglass batt insulation between framed stud walls of the basement interior with a vapor barrier over the studs is no longer recommended because in order to maintain long-term effectiveness, fiberglass should not be exposed to the high-moisture conditions that are found in basements.
Does Fiberglass Dust Causes Cancer?
YES. In 1993, the government declared that fiberglass dust is “reasonable anticipated” to cause cancer. Similar to asbestos, fibrous glass is potentially lethal when its microscopic fibers become airborne and are inhaled. Thus, fiberglass insulation should be enclosed in walls where the fibers will not become airborne.
