Fire rate products? Hello I need 1 hour fire rated product on a curved wall...
Hello I need 1 hour fire rated product on a curved wall beside 18 inch diameter. The curve is between the ceiling and a wall. It needs to be 1 hour fire rated ULC approved. approx. 30 foot square is the area. Any suggestions?
Answers: To get the 1 hour rating on a wall, you have need of to use 5/8" Firecode drywall. The tight radius presents a problem, but it's not too hard to overcome. Wet the backside of the sheet, and using a strap clamp start to bend the sheet. Don't try to get it adjectives at once. When it dries, wet it again, and tighten the clamp. Repeat until you have your radius. Hope this help.
EDIT: Bending the rock will not affect the fire rating, as long as you don't break the sheet. That's the reason for doing this in stages a bit than all at once. Good luck.
