Description
VaporTite is a self-adhered vapor barrier membrane for steel
decks 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 adhesive under
the surface. The material is installed with a 3-in (76 mm) side
lap and 6-in (152 mm) end lap.
Application
VaporTite membrane may be installed on a steel deck, plywood,
gypsum or concrete barrier boards, or structural concrete. Except
for the steel deck, all substrates must be primed with FTR SA Primer.
All surfaces must be clean and dry prior to application of the primer.
The minimum application temperature for VaporTite is 32°F (0°C).
Storage
VaporTite is packaged in boxes with 25 per pallet. Store boxes/
rolls of product on end on a clean and flat surface elevated
above the deck. Do not store in a leaning or horizontal position
as deformation may occur. All materials shall be stored in a dry
place, out of direct exposure to the elements. VaporTite shall be
handled in such a manner as to ensure that it remains dry prior
to and during installation.
Approvals
VaporTite is FM Approved for specific FiberTite assemblies
and listed in RoofNav. Note: FM does not permit self-adhered
membranes to be installed direct to steel decks.
