Fire Halt
Gyproc 90 Fire Halt Sealant Setting Compound

A fireproofing sealant that is easy to use and inexpensive. Simply add water and you're ready to seal walls around all kinds of pipes, conduits, beams and ducts in all your fire-rated assemblies. No mineral wool is needed so you save time and aggravation.

Fire Halt is also resistant to passage of smoke and airborne sound. It may be used in assemblies designated as "Smoke Barriers" or those required to meet a sound attenuation or STC rating.

Fire Halt contains special glass fiber filaments to improve crack resistance and bulking characteristics, and is tinted a reddish color to help Building Officials and Fire Marshalls distinguish it from normal joint treatment products.
