M-Weld

Adjustable M-Vent

Why M-Weld™ Pre-Flashed Accessories?

Conventional field-built penetration flashings are among the most notorious leak sites on the roof. But M-Weld™ Pre-Flashed Accessories offer consistent, factory-built quality every time, reducing the possibility of leaks and callbacks. M-Weld™ Accessories work with torch, hot bitumen, or cold adhesive applied systems. 

Choosing uniform, pre-flashed accessories over field-built solutions results in a neater finished appearance and can lower installation costs by up to 6%! Available in a wide variety of standard styles and sizes, plus custom-fabricated styles to meet specific job requirements. The Adjustable M-Vent™ allows for waterproofing of tall or awkward roof protrusions.

Benefits

  • Convenient:  Spun-aluminum design eliminates seams and soldered joints.
  • Versatile:  Accommodates protrusions that exceed 12" (305 mm) in height and any diameter up to 12" (305 mm).
  • Lower Labor Costs:  Helps eliminate callbacks and labor costs.
