DESCRIPTION:
Duro-Guard
®
Sopravap’r is a self-adhesive vapor
barrier membrane composed of SBS modified
bitumen adhesive on the bottom surface and a tri-
laminated woven polyethylene on the top surface. A
silicone release film covers the self-adhesive on the
bottom surface.
Sopravap’r can be used within a Duro-Last
®
roof
system to minimize vapor transmission. Duro-Last
recommends the use of vapor barriers, however it is
the responsibility of the Duro-Last contractor of
record to ensure that all applicable specifications,
building codes, regulations and ordinances are
complied with and followed. A roofing professional,
such as a consultant or architect, should be utilized
for correct roof system design prior to installing any
roof system.
Sopravap’r can provide a durable, walkable,
temporary surface that protects the decking for up to
4 months until a Duro-Last system can be installed
(See Figure 1). Temporary roofs do not carry any
type of warranty and must only be used at the
discretion of a roofing consultant or architect.
