	Duraclad Duraclad is a 40 mil peel-and-stick roofing underlayment comprised of two layers of an SBS modified bitumen surrounding a polyester fiber core. Regular Duraclad features a reflective white fabric top surface for foot traffic safety and increased ultraviolet light resistance. Smooth Surface Duraclad features a smooth black asphalt surface for accepting bituminous coatings. A two-piece release film on the bottom surface facilitates positioning of the sheet prior to final placement. Removal of the release film allows the sheet to adhere to the surface below. Bonding is immediate and facilitated by slight pressure. Duraclad is a self-sealing around screws, and its high grade asphalt resists decay and decomposition.
	Duraperm Duraperm Vapor Barrier is a 20 mil peel-and-stick vapor barrier made of SBS modified bitumen, surfaced with a gray/white polyethylene film. Bonding is immediate and facilitated by slight pressure. Duraperm's self-sealing qualities around screws have been tested, and Duraperm retains vapor barrier performance with as many as 10 screws per square foot!
	Duraperm ES Duraperm Extra Strength is identical to regular Duraperm except that it is surfaced with a cross-linked polyethylene film which gives it the strength necessary to span the open flutes of the deck. Therefore, Duraperm Extra Strength may be installed directly over steel deck. Bonding is immediate and facilitated by slight pressure. Duraperm's self-sealing qualities around screws have been tested, and Duraperm retains vapor barrier performance with as many as 10 screws per square foot!
U.S. Patent No. 5,584,153	Duratrax Duratrax is a concealed fastening system designed to function within the Loadmaster Roof Deck Assembly. It provides anchorage for roof coverings that require mechanical attachment. Duratrax consists of a series of galvanized steel channels embedded in the insulation underneath the top layer of Duraflex Mineral Board. The Duratrax channels may be screw attached through the insulation to the deck or they may be free floating, the Duraflex Mineral Boards hold the Duratrax channels in place against upward movement. The legs of the Duratrax channel, which are embedded downward prevent lateral movement. Duratrax channels are from 2" to 4" wide and range in thickness from 18 Ga. to 25 Ga. Duratrax is recommended for use with tile, slate or metal panel roofing.
