A Stronger Performance

TopSpec® by WeatherBond Reinforced EPDM membranes get their strength from a strong polyester reinforcing scrim-sandwiched between two plies of EPDM membrane. The polyester reinforcement more than doubles puncture resistance compared to non-reinforced membranes. For rooftops where long-term puncture resistance is essential, the dual-ply construction of the reinforced membrane is the ideal solution as it resists cuts, tears and scuffs.

Fully Adhered Roofing System

TopSpec® by WeatherBond Reinforced EPDM membrane may be used on TopSpec® by WeatherBond fully adhered roofing system installations. An acceptable insulation is mechanically attached to the roof deck; or adhered with adhesive and the membrane is adhered to the insulation using EPDM Bonding Adhesive. Adjoining sheets of membrane are spliced using TopSpec® by WeatherBond’s Pre-Applied Seam Tape or TopSpec® by WeatherBond’s Peel & Stick Seam Tape and primer.

Mechanically Attached Roofing System

TopSpec® by WeatherBond Reinforced EPDM membrane can be integrated into TopSpec® by WeatherBond’s Mechanically Attached Roofing System. Insulation is mechanically attached to the roof deck and the membrane is mechanically attached with fastening plates, polymer or metal fastening bars and the appropriate fasteners. TopSpec® by WeatherBond’s Reinforced Perimeter Strip effectively secures the roof perimeter.
