Versiweld Premier is a heat-weldable single-ply membrane designed for new roof construction and reroofing applications.
Versiweld Premier thermoplastic polyolefin (TPO) membrane is based on advanced polymerization technology that combines the durability and weatherability of ethylene-propylene (EP) rubber with the heat weldability of polypropylene. The membrane is specifically formulated for long-term weather resistance without the use of either polymeric or liquid plasticizers. Physical properties of the membrane are enhanced by a strong, polyester fabric that is encapsulated between the TPO based top and bottom plies.
The combination of the fabric and TPO plies provide Versiweld Premier reinforced membranes with high breaking and tearing strength and puncture resistance. The relatively smooth surface of Versiweld Premier produces a "total surface fusion weld" that creates a consistent, watertight monolithic roof assembly.
Versiweld Premier is available in highly reflective white, tan and gray .045"-and .060"-thick reinforced membrane. Available widths are 4 and 5-ft perimeter sheets and 8 and 10-ft. field sheets. The membrane is environmentally friendly and safe to install (particularly during welding) because it is free of chlorinated polymers or chlorine containing ingredients.
Versiweld Roofing Systems are fast to install since minimal labor and few components are required. The systems may be installed utilizing laborsaving devices that make sheet welding easy to learn, clean, and consistent, while reducing strain on the roofing technician. The Mechanically Attached Roof System installation starts with the insulation being fastened with a minimum of 5 fasteners per 4 by 8-ft. board.
The Versiweld Premier reinforced membrane is mechanically attached a maximum of 18" on center for FM 1-60 rating using the appropriate Versico fastener and plates. For higher wind resistance, the membrane fastening must be 12" on center for 1-90 and 6" on center for 1-120 ratings.
The Fully Adhered Roofing System application begins with the insulation being fastened at the required density (max.1 every 2 sq. ft) for the necessary rating. The substrate and membrane are coated with Versiweld Bonding Adhesive and the membrane is rolled into place. Contact your Versico representative for the specific design requirements and installation procedures for these systems.
