What is a 30 minute rated wall?

What is a 30 minute rated wall?

Most Type X drywall has a one-hour fire rating. The fire rating for the 1/2-inch drywall used throughout the rest of the home is 30 minutes. As an added benefit, Type X drywall absorbs sound slightly better and is slightly stronger than conventional 3/8-inch or 1/2-inch drywall.

What is a 2 hour fire rated wall?

Double the number of Type X sheets on the wall for a simple system installed over fire-resistant fiberglass insulation; each sheet of 5/8-inch Type X drywall is rated to resist fire for one hour, so two layers will produce a two-hour firewall.

How thick is a 3 hour fire rated wall?

(25 mm) thickness (measured perpendicular to the face of the wall) of ceramic fiber in the joint can be used in walls with fire resistance ratings up to 3 hours, while a 2 in. (51 mm) thickness can be used in the joints of a 4-hour wall.

What is fire rated assembly?

A. A fire-resistance rating refers to the period of time an assembly is able to contain a fire and perform its intended structural function. These ratings are determined by subjecting an assembly to a standard fire exposure as defined in ASTM E119.

Does garage drywall need to be fire rated?

A: First, fire-rated systems are only required if the garage shares a wall or a ceiling with the home. If you are doing repairs in the garage you should replace with like materials, but remember it is the wall system that is fire rated not the product itself.

What is Type C drywall used for?

Type C is an industry phrase to designate enhanced gypsum panels that exceed the requirements for Type X gypsum board in ASTM C1396. 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.

What is required for a fire rated wall?

The required fire-resistance rating of exterior walls with a fire separation distance of less than or equal to 10 feet (3048 mm) shall be rated for exposure to fire from both sides.

Are concrete block walls fire rated?

Concrete masonry is a noncombustible construction material possessing excellent fire-resistive properties. The resistance of concrete masonry to fire is well established by extensive testing to be a function of the type of aggregate used in the manufacture of the masonry units and their equivalent thickness.

What kind of drywall do you use around a fireplace?

Drywall + Fireplace = House Fire Unfortunately, this is highly flammable and is not an appropriate or safe fireplace surround. The sheetrock had to be removed and replaced with any type of non-combustible surround – stone, tile, marble, or metal.

What is Type S drywall?

There are three different types, which are optimized for different applications: S, W and G. Type S has fine threads and a sharp point and is intended to fasten drywall to steel studs less than 0.033″ thick.

What makes a 1 hour fire-rated wall?

Ratings for fire resistance are given in accordance to the time a structure can contain a simulation fire. More specifically, if a wall is constructed in a manner that closely resembles a tested wall which has shown to contain flames and high temperature for one hour, it is eligible to receive a 1-hour rating.
