Membranes

With superior durability and flexibility, EPDM is a smart roofing solution. 

Our EPDM production facility is one of the world's most technologically advanced, allowing us to extrude our sheets instead of using the traditional calendering process.

Our EPDM is manufactured thicker with a more uniform surface finish. This advancement in manufacturing cleaner sheets requires less preparation to ensure a stronger bond during installation.

Seals a JM EPDM roofing system joining a bituminous membrane.

JM EPDM Metal/Membrane Flashing is a specially designed and manufactured flashing for sealing and waterproofing JM EPDM roofing systems where they join an adjacent bituminous roof membrane. It is comprised of a nominal 6" (15.24 cm) strip of JM EPDM membrane secured (using a patented method) to flanges of nominal 4" (10.16 cm) wide, Type 100G-6, galvanized steel.

Membrane: Nonreinforced, cured EPDM (ethylene propylene diene monomer).

Fully Extruded: Produces fewer air voids, more uniform thickness and smoother sheets.

Vulcanization Process: Combines two layers of membrane to produce a fully cross-linked monolithic membrane.

Membrane Formulation:
Performs in extreme temperature climates and withstands differential movement (elongation).

UV-Stabilization Properties:
Offers outstanding ozone and weather resistance delivering one of the longest service lives available.

Technical Expertise:
Backed by 30+ years of EPDM experience and installations.
