Welding of Single-Ply Membranes on Flat Roofs

Economical and Safe

Plastic Welding Flat Roof
VARIMAT V2
Leister offers economically-priced and ergonomically-designed hot-air welding machines for the overlap welding of single-ply (PVC, TPO, EPDM, etc) roofing membranes on flat roofs.

  • The VARIMAT V2 achieves a unique speed of up to 12 meters (39 feet) per minute. Flat roofs are quickly and safely made leak-tight—thanks to consistent welding parameters which are digitally-monitored and can easily be modified—even in adverse weather conditions.
  • The easy-to-handle UNIROOF AT really proves its worth, often in locations which are difficult to access, in the immediate vicinity of walls or on smaller roofs with little room to maneuver.
  • The small, TRIAC DRIVE AT semi-automatic welder, is suitable for boarding and channels.
  • Before the base seam is actually welded, the seam quality can be assessed using Leister's EXAMO tensiometer.
  • Leister offers tried-and-tested handheld welding tools (heat guns) for all precision work—above all the TRIAC ST/AT—which impress users with their robust design and reliability.



Leister has the solution
Whether for ergonomic, economical welding of thermoplastic single-ply membranes, or  heat guns and matching accessories (for working on small roofs, details and in inaccessible locations), Leister has the solution.

 

  • Hot-air welding machines with digitally-controlled technology for reliable welds
  • Complete tool range for all applications
  • Maximum welding speed
  • Long service life with low maintenance requirements
