Elastomeric Single Ply Roofing

These are synthetic rubber variety and are classified into two categories, vulcanized elastomers and non vulcanized elastomers.

Vulcanized elastomers are cured polymer membranes in which the overlaps can be bonded by adhesives as the reaction is irreversible

Example: EPDM- Ethylene propylene diene monomer membranes

Non vulcanized membranes are the uncured polymer membranes which cure on the roof over a period of time. Cold applied adhesives are used for bonding overlaps and to the substrates.

Examples: CSPE- Chlorosulfonated polyethylene (Hypalon), CPE- Chlorinated polyethylene, and PIB- Poly isobutylene.
