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 the use of crickets, many roof designs still don’t eliminate ponding around the drain area. Hand cut drain sumps are even worse 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 either a 1.5" or 3.0" 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.

Tapered ACFoam Composite/GB consists of Atlas closed-cell polyiso foam bonded to 1/4" or 1/2" primed glassmat gypsum board on the top and a fiber-reinforced felt facer on the bottom.It is manufactured in a tapered profile to attain positive drainage. The glass-mat gypsum board provides a dense protection layer for the primary foam insulation and has a 500-psi compressive strength, which makes Composite/GB a good choice where foot traffic is a concern. Available in 4´ x 4´ (1220mm x 1220mm) only.

In 1998, years ahead of the Environmental Protection Agency timetable for eliminating HCFCs (hydrochlorofluorocarbons), Atlas introduced a line of ACFoam Products that are environmentally sensitive and available for virtually every type of construction system. Through a patented hydrocarbon blowing technology called ACUltra, Atlas began the phaseout of HCFCs in the manufacturing of foam insulation and anticipates the complete removal of HCFCs from all Atlas foam products within the next year.

Tapered ACFoam Composite/PB consists of Atlas closed-cell polyiso bonded to 1⁄2" perlite on the top and a fiberreinforced felt facer on the bottom. It is manufactured in a tapered profile to attain positive drainage. The perlite top eliminates the need for cover boards or vented base sheets normally recommended over foam insulations. Tapered ACFoam Composite/PB may be used with BUR, modified bitumen, and certain single-ply systems. Available in 4´ x 4´ (1220mm x 1220mm) only.

Tapered ACFoam Composite/FB consists of Atlas closed-cell polyiso bonded to 1⁄2" high density wood fiberboard on the top and a fiber-reinforced felt facer on the bottom. It is manufactured in a tapered profile to attain positive drainage. The wood fiberboard top eliminates the need for cover boards or vented base sheets normally recommended over foam insulations. Tapered ACFoam Composite/FB may be used with BUR, modified bitumen and certain single-ply systems. Available in 4´ x 4´ (1220mm x 1220mm) only.
