Description
The ChemLink ChemCurb 12-In Straights are precast, straight curb sections used to build linear portions of roof curb flashing assemblies. These components are part of the ChemCurb system and are engineered to be combined with other system parts — such as corners and rounds — to create a continuous perimeter around roof penetrations and curbs.
The straight sections are made from a durable precast resin and form part of the structured flashing system that works with compatible sealants and accessories to integrate the curb with the roofing membrane.
Key Features
- Precast straight curb components for ChemCurb flashing systems
- 12-inch length for extending curb assemblies
- Gray precast resin construction
- Designed to integrate with ChemCurb rounds, corners, and accessories
- Forms part of a continuous flashing solution around roof penetrations
Installation
Bonding surfaces should be clean, dry and free from all contamination that may inhibit the sealant’s performance. Remove all previously applied caulk, mastic, cement, asphalt, and other contaminants from penetrations with a wire brush. Brush away all gravel or loose granules. Isopropyl alcohol is an effective cleaner for surface preparation. Do not use on TPO without the use of TPO primer. Do not use on Hypalon. Smooth APP membranes require a granulated target. This product sets rapidly upon exposure to moisture.
