The 5/8-inch, “fire-code” drywall (called Type X) increases a wall’s fire rating to a minimum of 1 hour, from the 30-minute rating for standard ½-inch drywall. And it’s not just thickness that makes the difference. Type X has a denser core and contains glass fibers that keep it from crumbling in the heat.
Type C panels typically have a shrinkage-compensating additive, and when exposed to heat, the Type C gypsum board expands providing more fire-resistance at joints and seams. … For other gypsum boards including Type X, although they are all non-combustible, shrinking occurs when exposed to a flame or heat.
A: Both drywall Type X and Type C are approved for use in a 60-minute rated design. The wall systems they are approved for are different, however. Type C fire-rated drywall has more glass fiber reinforcement and other ingredients in the gypsum core that makes its fire-resistive properties superior to Type X.

For best results when painting DensArmor®/ DensArmor PlusTM , G-P Gypsum requires the use of a high quality, high build drywall primer/surfacer. Follow the application instructions of the primer manufacturer stated on the container.
eXP® Sheathing consists of a moisture- and mold-resistant gypsum core encased in a coated, specially designed PURPLE fiberglass mat on the face, back and sides. The glass mat is folded around the long edges to reinforce and protect the core, and it provides superior weather resistance.
Physical Description. Exterior Gypsum Sheathing is a special-purpose drywall panel consisting of a moisture-resistant, noncombustible core covered by glass-mat facers on both front and back surfaces and long edges.
Typically one layer of Type X drywall promises 45 minutes to one hour of fire protection for the building constructed with this type of material.
According to the Engineered Wood Association, a one-hour rating indicates that a wall constructed in a manner similar to the one tested will contain flames and high temperatures, and support its full load, for at least one hour after the fire begins.
Drywall is relatively fire resistant. It’s composed of gypsum pressed between two sheets of thick paper. Gypsum is a soft mineral that by itself is not flammable. … The glass fibers are non-combustible and help maintain the integrity of the drywall as it is dehydrated.
Fireproof drywall is the common term; its industry name is Type X drywall. The thickness of this drywall is 5/8-inch, including all layers. Glass fibers are added to the board to help it retard fire. … Most Type X drywall has a one-hour fire rating.
The paper facing or other facing type on gypsum board has flame spread indices that vary but are less than 50, since the ASTM standard for gypsum board requires a flame spread index of 25 or less. Thus, gypsum board products are considered noncombustible materials per the IBC.
Noncombustible (as described and tested in accordance with ASTM E136) ToughRock® Fireguard C® Gypsum Board is designed for use in a variety of interior drywall applications for wall and ceiling construction in assemblies with a designated fire-resistant rating.
The total fire rating is determined by adding each component to reach a minimum total of 60 minutes. Fire protection rating is calculated from the flame side of the assembly and of course some assemblies have multiple flame sides. Your wood framing members are required to be not more than 16″ on center.
What about the wall between the house and garage? The wall between the house and garage is not a firewall, nor is it a fire-resistance-rated wall. The wall between a house and an attached garage does have some special requirements, however.
Type 1: Fire-resistive: High-rise buildings made of concrete and protected steel. Type 2: Non-combustible: Newer buildings with tilt slab or reinforced masonry walls and a metal roof. Type 3: Ordinary: New or old buildings with non-combustible walls but a wood-framed roof.

The PURPLE family of products delivers innovative performance that goes well beyond what’s possible with standard drywall. While all gypsum-based drywall is naturally fire-resistant, the PURPLE family of products is unique because it also resists moisture, mold and mildew.
Green board drywall, also known as moisture-resistant drywall, has a green covering that makes it more resistant to moisture than regular drywall. … It is also often used as a tile backer in limited wet areas such as bathroom and basement walls, plus kitchens, and laundry and utility rooms.
“Green drywall (also known as greenboard) is only moisture-resistant. PURPLE®drywall, only made by National Gypsum, is superior because it offers moisture, mold and mildew resistance. In addition, many PURPLE® drywall products offer added benefits, including resistance to scratches, scuffs, dents and sound.
Paperless drywall was developed recently in order to combat problems with mold. … Paperless drywall is similar to traditional drywall in that it also contains a gypsum core. The difference is that instead of using paper as an outer wrapping, fiberglass is used instead.
Water-resistant gypsum backing board contains additives in its core that provide water resistance and its face and back paper are treated to limit water absorption; however, water- resistant gypsum backing board is NOT WATER-PROOF.
Glass mats are made through randomly distributed glass fibers onto a conveyor belt, and bonded together with a binding agent. … The glass mat technology is found in many industrial applications such as roofing, insulation, flooring, wall covering, ceilings, and others.
However, people generally confuse it with water-resistant drywall. Water-resistant drywall is commonly referred to as green board in the trade. However, mold-resistant drywall doesn’t have the paper facing and has fiberglass instead. Paper is an organic material that ultimately can become mold and mildew food.
Space prone to moisture such as bathrooms and laundry rooms are also typically most prone to mold – which can be disastrous and costly to the structure of your home. Walls and ceilings in these spaces that are often damp due to humidity or splashing are suitable for mold-resistant drywall.
