Chem Link will exhibit its E-Curb System Penetration Seals for roofing and solar contractors at Intersolar North America 2012 on 10-12 July at the Moscone Centre (booth 9351) in San Francisco, California (US). The E-Curb System is comprised of precast, lightweight reinforced nylon forms to contain the 1-Part Pourable Sealer and the M-1 Structural Adhesive/Sealant used to seal the penetrations and bond the forms to the roof. No mechanical attachment is necessary.
The E-Curb is a modification of the ChemCurb Penetration Seal System, introduced in 1995 by Chem Link for commercial rooftop penetrations as a solution to the insufficiencies of pitch pans. More than 1 million ChemCurbs are now in service throughout North America. Like the ChemCurb System, the E-Curb System was developed in response to requests from contractors in the field. The proliferation of solar panels has created a need for more efficient installation methods. The E-Curbs install in less time than traditional pitch pans and reduce labour on all types of roofs. Up to a 20-year warranty is available.
E-Curb precast forms are provided in a variety of sizes and shapes to secure and seal solar supports. The 3-inch ("), 4", 6" and 9" bisected circular slip-fit forms permit rapid assembly around penetrations. (Note: 1 inch equals about 2.5 centimetres.) The 8" straights and corners with a 2" radius permit larger oblong, rectangular or square seals. The forms are 2" high with a flanged base that allows for external flashing with the M-1 included with the kits. They are impenetrable to ice, corrosion, ultraviolet (UV) light and ponding water.
M-1 and 1-Part are the heart of this system and provide excellent adhesion on most types of low-slope roofs in damp, dry or cold climates. Both are polyether-based, moisture cure, 100% solids, contain no harmful solvents or toxic materials and will never shrink or outgas. ("Polyether-based" chemistry means that they will never pose any harm to humans or the atmosphere, because they contain no solvents or toxic substances. "Moisture cure" means that the higher the temperature and humidity are, the faster the rate of cure will be.)
For steep-slope roofs, where pourable sealer could cause problems, DuraLink Super Adhesion Sealant is a gun-grade polyether sealant that will provide the same secure seal. It also is 100% solids, solvent-free, moisture cure and non-shrinking. It is extremely elastic and bonds effectively to many difficult surfaces including anodized metals and coatings such as Kynar 500 polyvinylidene fluoride (PVDF). M-1, 1-Part and DuraLink meet or exceed all regulatory compliance requirements and are Leadership in Energy and Environmental Design (LEED), California Air Resources Board (CARB) and Over the Counter (OTC) eligible. Chem Link also supplies solar mount accessories for shingle and low-slope roofs.
