There is a self-adhesive fire-rated tape available that doesn’t require a coat of joint compound to maintain its fire rating. It is an excellent choice for fire-taping gable ends and attics. Use the right tape: Fire tape is a self-adhesive drywall tape that does not require joint compound to achieve its fire rating.
The term fire resistance means the ability of a constructed assembly (a wall or a ceiling covered with drywall) to contain a fire. The fire-resistance rating for each thickness of drywall is measured in intervals of time: 45 minutes for 1/2-in. fire-resistant drywall, 60 minutes for 5/8-in. panels, and 120 minutes for 3/4-in. panels.
What’s the Difference: Fire-Resistant Drywall. Type X and type C drywall are designed specifically to be used in fire-rated assemblies. By Myron R. Ferguson Issue 193. Glass fibers enhance fire resistance. Added to the core of type-X and type-C panels, noncombustible glass fibers help gypsum panels to resist crumbling during a fire.
Drywall is not necessarily fire rated just because it is 5/8 inch. Drywall can be non-fire rated in 5/8 inch, but it is probably something you'll never see. All drywall is non-combustible, but not all drywall is fire resistant. When drywall is exposed to heat the gypsum core crumbles, though it doesn't burn. If you wanted a wall that would not ...
Attach metal Angle iron to the inside edge - your access panel will attach to this. Make the access panel out of drywall, with the entire outside edge made of the metal end cap. You will make it in place, attach it to the L with a bolt. Drill a hole though the drywall and L, then tap the hole for a 1/4" or 5/16" thread.
Apply a strip of joint compound approximately ½ in. thick and 5 in. wide every 16 in. or 24 in. (depending on the framing spacing). Then use a notched trowel to groove the compound and leave beads of compound 3/8 in. wide by ½ in. high and spaced 1 in. apart. When using this method for wall applications, pre-bow the panels (with the bow ...
This extra strength means long-term savings on repairs and replacement costs. Abuse-resistant drywall is available in 1/2-in. panels and 5/8-in. fire-resistant panels. The 5/8-in. fire-resistant panels are ideal in garages, utility rooms, and commercial work areas, where a high fire rating is necessary. Sign up for eletters today and get the ...
Half-inch steel might survive the worst fire - but it passes enough heat to start a new fire after about 12 minutes. Thus, you don't see steel firewalls. The primary factor in fire resistance is the simple thickness lof the drywall. Double the thickness and you double the time it will take for the fire to burn through.
Scott Gibson defines the labels "noncombustible," "combustible," "ignition resistant," and "fire resistant," so you can choose the best and safest materials for your home. This article originally appeared as part of Building to Survive in Wildfire Country. When researching, designing, and choosing materials for a home in a wildfire-prone area ...
The added mass of5/8" is definitely a better sound absorber. The added cost is mostly in the extension jambs for trim. 5/8" is required on cielings where the span is more than 16" OC. 1/2" will eventually sag at spans over 16" and even at 16"oc in some situations.
