The primary and differentiating feature of Maxell Airtight Products (M.A.P.) and flashing materials is its “Quick and Easy Installation”. The MAP-S15 serves as the primary solution for standard residential drain, waste, and vent (DWV) lines. While the smaller S00 through S10 models focus on supply lines and wires, the S15 is the first “large-format” sheet designed to handle the thicker pipes common in modern plumbing.

Because 1 1/4″ and 1 1/2″ are standard sizes for secondary drainage, making the MAP-S15 ideal for:

1. Bathroom & Kitchen Drains
2. HVAC Condensate Drains
3. Radon Mitigation Venting
4. Sump Pump Discharge
