Dow Protected Membrane Roof EN - Manual (Page 7)

Description
STYROFOAM ™ extruded
polystyrene insulation is a rigid,
closed-cell insulation, ideally
suited and designed for PMR
installations. Because of the
properties imparted during the
extrusion process combined
with the hydrophobic nature
of polystyrene, STYROFOAM
insulation has a high resistance
to both water and water vapor,
providing demonstrated long-
term mechanical and thermal
performance.
The boards are available in a
range of thicknesses, densities,
and edge and surface treatments.

STYROFOAM ™ ROOFMATE ™
An extruded polystyrene foam insulation
providing excellent moisture resistance,
durability and long-term R-value. Ideal
for installation above waterproofing or
roofing membranes in PMR applications.
STYROFOAM ™ Ribbed ROOFMATE ™
An extruded polystyrene foam insulation
board with 1/4" x 1/2" drainage channels
on the bottom long edge of each board.
The top surface of the board has ribs that
form corrugations in the long dimension
of the board.
Designed for installation above water-
proofing or roofing membranes in PMR
applications that use pavers as ballast.
Pavers can be installed directly over the
ribbed foam surface without needing
pedestals.
STYROFOAM ™ PLAZAMATE ™
A high-density extruded polystyrene foam
insulation board designed to be installed
above waterproofing or roofing membranes
in most plaza deck applications.
STYROFOAM ™ Highload 40, 60 and 100
An extruded polystyrene foam insulation
board with high compressive strength
developed specifically for in-ground
application and freezer floors. The prod-
ucts are also well-suited for plaza decks
and protected membrane roofs that must
withstand heavy traffic.
