Single Ply Roofing
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
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.
