M-Weld Drain Insert

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.

Standard M-Drain™ is a spun-aluminum or copper roof drain with gravel guard, strainer caps, and waterproofing plumbing seal attached. M-Drain™ is pre-flashed with either APP or SBS smooth-surface modified bitumen membranes, and is available in full and insert sizes to accommodate new construction and retrofit applications. Unflashed M-Drain™ is also available. The Drain Insert is a spun-aluminum or copper roof drain with gravel guard, strainer caps, and waterproofing plumbing seal.
