09 20 00/THE Shaft Alternative Enclosure Products BuyLine 8865 Thermal Ceramics, a global manufacturer of high temperature insulation prod- ucts, has provided engineered solutions for heat containment problems for over 75 years, and was the first to develop flexible fire resistive duct enclosures, mar- keted under the brandname of FireMaster, for commercial kitchen grease and air ventilation ducts. Unlike imitation wraps in today’s market, Thermal Ceramics has the widest range of duct enclosure products that are performance-tested beyond minimum laboratory listings or code requirements. This assures fire containment, from the typical to the most complex duct designs, without theorizing. Thermal Ceramics innovative duct products are high temperature (2000°F) fire rated solu- tions that do not age, become brittle, or shrink during in-service operations, like lower temperature mineral wool wraps. The duct products in the FireMaster line are resistant to mold growth in test conditions of 75-95% relative humidity (ASTM D6329). With zero flame and smoke ratings on the blanket, and only a 5 flame spread and 10 smoke rating on the foil encapsulation, Thermal Ceramics duct products do not add toxic emissions to fire conditions. With a vast number of field installations worldwide and over 20 years of successful fire containment in real- world fires, the duct products in the FireMaster line have proven their worth.

Red Star Tavern and Road House, Portland, Oregon A grease duct fire at the Red Star Tavern and Road House, demonstrated the relative performance of a gyp- sum shaft enclosure and FireMaster Duct Wrap insula- tion methods on the same grease duct exhaust system. The FireMaster Duct Wrap effectively prevented the fire, and there was no escape of flame or fumes. However, the gypsum shaft enclosure failed, and spawned multiple fires causing $150,000 in damage. Instead of protecting the structure, the gypsum enclosure with its air gap actu- ally promoted the rapid spread of flames. When the Red Star Tavern and Road Burned gypsum shaft building was rehabilitated, Portland building officials House required that the entire duct be protected with foil encap- sulated FireMaster Duct Wrap.

FireMaster Duct Systems versus Drywall Board Shaft Enclosures Even when built according to code, there are concerns for the performance of a drywall board enclosure under grease duct fire conditions. The concept of a two-hour rating for a drywall shaft enclosure is based on standard building conditions which does not take into account the unique fire behaviors that occur within grease and air ventilation ducts.
