Fire Rated DoveTail Deck (UL)

DoveTail roof decks may be used in assemblies which are required to meet hourly fire ratings. Hourly fire rated assemblies are a combination of specific proprietary materials as listed in the UL fire resistance directory. The fire resistance directory can be found at www.ul.com. Navigate to the Online Certifications Directory and search for Fire-resistance-rated Systems and Products.
 
Table 2: DoveTail Deck Fire Resistance Rating
lists the UL fire-rated assemblies utilizing DoveTail roof deck profiles. For full details of construction including specific information about fill or fireproofing thickness and span limitations, refer to the particular UL assembly listed in Table 2. Note that P9XX series assemblies do not require fire proofing on the deck, only on the steel support members.
