Pre-Manufactured One-Piece Gemini™ Drain Sets Are An Essential Feature of a Well-Designed Roof System
Even with the use of tapered insulation and crickets, many roof designs still fail to eliminate ponding around the drain area. Hand cut drain sumps are even less efficient because contractors often cut off facers, resulting in membrane adhesion problems, or uneven slopes to the drain which could cause ponding.
Atlas has developed the perfect solution with this one-piece 4' x 4' sloped polyiso drain set. Available with a 1.5" maximum thickness. Gemini™ Drain Sets install quickly, save labor costs, and eliminate rooftop waste. And Atlas Gemini™ Drain Sets are designed to mate perfectly with Atlas tapered insulation panels and Gemini™ Crickets.
