E-Curb System – Penetration Seals
E-Curb penetration seals replace old-style metal pitch pans with versatile, precast components and pourable sealants. Chem Link’s E-Curb System can usually be installed in under 15 minutes and never requires flashing or mechanical attachment. They are designed for use on granulated modified bitumen, asphalt and coal tar B.U.R. (built up roofing).
E-Curbs are specified for PVC, PIB, and TPO single ply roofing membranes. The curbs are highly versatile for sealing penetrations around solar panel mounts, HVAC, Electrical, and any type of structural supports. TPO Primer is required for use with TPO. When installed properly, this system forms a durable, waterproof rubber seal around penetrations. An extended warranty against leaks is activated with submittal of a completed warranty card.
