Good to Know

Questions about Fire-Rated Drywall & Ceiling Systems

Half hour, one hour and two hour, tested to BS 476 Part 22 and international standards. The rating belongs to the complete system - board plus framing - not to the board alone.

From 66 to 198 mm depending on the rating and acoustic requirement, and they can be built up to 10 metres high with a special structural design.

Up to 44 dB, which is why they are used in hotels, hospitals, theatres and offices as well as for fire compartmentation.

Yes - they are built for humid environments and resist moisture, termites, fungi and corrosion, unlike gypsum board in the same conditions.
