Duro-Last® Roofing, Inc. is introducing its Duro-Bond™ system, providing a mechanically-attached roof installation option using non-penetrating “induction weld” technology.

Induction welding bonds Duro-Last’s PVC membrane to a specially-coated fastening plate beneath the roof membrane; the same plate also fastens insulation and recovery board materials to the roof deck. An induction welding tool generates an electromagnetic field that heats the plate through the membrane, welding the plate’s special coating and bottom PVC membrane film layer together, forming a very strong bond between the two. An induction weld installation does not create any point of entry for moisture, requires fewer fasteners, and provides superior wind uplift performance.

Traditional mechanically-attached installations require fastening the membrane to the roof deck through membrane “tabs,” usually located where sections are seamed together. However, with the Duro-Bond system, seam and tab fasteners are not necessary. The installing contractor simply determines the number of fasteners required to achieve the desired wind uplift rating and spreads them across the roof in a grid pattern. The uplift load will be distributed evenly and the system can achieve excellent wind ratings with fewer fasteners.

Steve Ruth, Duro-Last’s Vice President of Sales and Marketing, said, “Our standard Duro-Last system is delivered to contractors in prefabricated sections that fit the roof dimensions; it’s already a quick and easy system to install. With the Duro-Bond technology, typically only a few seconds are required to bond the membrane to the plate, and the job can be performed by virtually anyone. Fewer fasteners and less time to install each one makes a fast application even faster.”

Additional Duro-Bond advantages:

  •     It is compatible with polyisocyanurate and many other insulation types.
  •     Unlike other systems, the Duro-Bond system can be used in virtually any weather conditions.
  •     No foul-smelling bonding adhesives are needed, making it ideal for hospitals, schools, and other occupied building applications.
  •     The Duro-Bond system is an excellent option for installing a Duro-Last roof in metal retrofit and some concrete deck applications. The fasteners are installed into the purlins for maximum uplift resistance, yet they do not have to be placed in the seams of the membrane. Therefore, membrane width and orientation are not factors in metal retrofit installations.

Authorized contractors have the choice of using Duro-Bond plates and welding tools made by OMG (the RhinoBond® Induction Fastening System) or FRS (the Centrix® Induction Bonding System). Plates and tools are available for purchase from Duro-Last by authorized contractors.
