Portals Plus, the premier manufacturer of stock rooftop
accessories,proudly announces the Premier Seal for Aluminum ReRoof
Drains!Portals Plus has developed a unique Mechanically Expandable
Rubber Seal, “The Premier Seal”. The Drain is designed to replace
existing drains in retrofit applications. All installation is conducted
on the roof surface. The seal is activated by tightening the internal
screws with the Premier Screwdriver. The Seal utilizes PVC flanges for
increased strength and stainless steel screws to compress the EPDM
rubber gasket. The compression of the seal expands it and makes contact
into the existing piping of the pre-existing drain, therefore,
preventing vertical movement and stopping water damage into the
building. The Premier Seal exceeds SPRI and ANSI Retrofit Drains
requirements. The unique Portals Plus ReRoof Drains are available now
in 3”, 4”, 5”, and 6” sizes in conjunction with the aluminum ReRoof
New die-cast high strength alloy Dome Strainer means fewer
debris-clogged drain lines due to broken domes. Further, the Dome
Strainer bolts down to prevent malicious vandalism to the drain system.
New die-cast high strength alloy Clamping Ring means secure and even
compression of the edge of the roofing system at the lowest point of the
roof and prevents backups under the system into the insulation.
Stainless fasteners mechanically locked to the flange mean that the
Clamping Ring can be truly tightened to seal the membrane without fear of
snapping soldered or aluminum studs.
New spun high tensile 22,000 psi .060” thick aluminum flange remains
flat for flush mounting and eliminates the water dam problem created by a
Flange prepunched for easy securement to the deck to control thermal movement and eliminate membrane stresses.
Machine welded gas-tight joint between flange and tube creates a
unitized construction which eliminates concerns about soldered joints
melting and leaking and avoids the internal stresses that cause cracking
in large one-piece spinnings.
Constant diameter extruded aluminum tube means a sure fit and allows
cutting at any point with the same diameter. This means that the seal
fits the same at any point on the tube and in the drain pipe, unlike
spun tubes which taper.
New Premier Seal! Utilizes white ABS plastic to ensure better
visibility during installation. Mechanical Seal provides water-tight installation.
