      Why M‑Weld™ Adjustable M‑Vent™?

      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

      Benefits of M-Weld™ Adjustable M-Vent™ include:
      • Convenient:  Spun-aluminum design eliminates seams and soldered joints.
