FireMaster DryerWrap
1. Product Description
Thermal Ceramics newest fire rated duct wrap product is
FireMaster DryerWrap for application on dryer vent ductwork in
multi- unit housing where fire compartmentation and life safety
are major concerns. FireMaster DryerWrap is tested and UL
Listed for 1-hour fire resistance on light gage construction up
to 7 inch diameter or 10x4 inch rectangular duct penetrating
1-hour rated wood joist gypsum floor therefore providing Owners,
Architects, and Engineers a viable and cost effective solution
for safely routing dryer exhausts from the laundry room to the
exit of the building. At 1 inch thick and 6 pound per cubic foot
density, FireMaster DryerWrap is 50% thinner, lighter, and
appreciably more flexible than any other alternative fire wraps
currently available. The optimized thickness and approved 1 inch
compression or overlap joints provide for significant installation
cost and space savings.

5. Installation
Materials and Equipment
• FireMaster DryerWrap
• 3” Tape (UL 181 Listed and Labeled)
• Serrated knife recommend
• 16 Gage galvanized steel tie-wire
• Wire cutters
Installation: Cut insulation to the length of the duct to be wrapped,
and tape seal cut edges using 3” foil tape. For 4” dryer ducts
the as supplied 20” width will be sufficient to provide for either a
1” compression or 1” overlap on the longitudinal joint. This long
joint may be tape sealed utilizing 3” foil tape at the contractors
discretion. Adjacent blankets or ducts wrapped using 48” width
blanket cut to a length sufficient to wrap around the duct are
installed with either a minimum 1” compression or 1” overlap at
the joint between blankets. Utilizing minimum 16 gage tie-wire,
cut wire to sufficient length to wrap the insulated duct and make a
small loop in one end. Wrap the tie-wire around the insulated duct
on maximum 8” centers. Where the insulated duct passes through
1-hour rated floor/ceiling assemblies, the penetration should be
framed out and the annular space packed with scrap FireMaster
insulation recessed minimum 1/4 inch from top surface. The
recesses space shall be filled with a UL Listed firestop sealant per
F-C-7055.
