ADVANTAGES OF JM EPDM.
THICKER
Tests indicate that competitors’ sheets are
consistently at the lower end of the ASTM tolerance
while JM sheets are much closer to a true 60 mil
(ASTM allows +/- 10 percent variation in sheet
thickness). Thicker sheets deliver a longer life cycle.
We give you more roof for your money.
CLEANER
Our commitment to
the EPDM market
begins in Milan, Ohio.
Our manufacturing facility in
America’s heartland is one of
the world’s most technologically
advanced. As the demand for
more comprehensive total
system solutions rises,
Johns Manville remains
invested and dedicated.
Advantages of black
EPDM over white roofs.
Cleaner sheets take less labor to prepare. A cleaner
surface will allow the tape to stick better, which
means a stronger seam and no contamination.
Black EPDM roofs can help
minimize energy consumption
and costs for building owners in
regions with more heating than
cooling days.
SMOOTHER
Strongest water-based
adhesive.
The smoother surfaces of these high-quality
sheets come courtesy of using the most advanced
extrusion technology available. Eliminating defects
(pockmarks and air inclusions) with a consistent
surface finish reduces the roofing membrane’s
weak spots.
With the rise in environmental
awareness and VOC regulations,
JM responded with an EPDM
water-based adhesive—one of
the most effective anywhere.
Stronger than the competitors’
products, it can be applied
vertically. It has a longer shelf
life and can also be an excellent
option where solvent odors are
not permitted.
Easy to install.
Easy to re-cover roofs.
EPDM is a very flexible system,
in part due to the availability of
different width sheets. EPDM
can be installed in a variety of
ways—adhered, ballasted and
mechanically fastened. EPDM
membranes make an excellent
re-cover choice, especially when
combined with a new layer of
JM insulation or Invinsa® cover
board, which creates a fresh
substrate, strengthening the
existing system.
