      Why M‑Weld™ One Way 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 M-Weld™ One Way M-Vent™ allows moisture vapor to escape out of the roof deck system without allowing moisture to enter through the valve.

      Internally, the M-Weld™ One Way M-Vent™ contains a neoprene valve that allows moisture vapor to escape out of the roof deck system without allowing moisture to enter through the valve.
