Accepted Materials - EPDM Membrane Systems

To view materials in any section listed below, click on the EXPAND button located at the right hand side of this page

1 Air and Vapour Control

The RCABC does not list air or vapour barriers in the Accepted Materials section of this Manual, as their performance is not guaranteed by the RoofStar Guarantee Program. For more about air and vapour barriers and specific requirements for the RoofStar Guarantee Program, select any of the Low Slope Membrane Roof Systems. This cross-reference is listed for information only.

2 Deck and Wall Overlays

Deck Overlays

Deck overlays are materials installed over decks to render the surface suitable for waterproofing materials. Click on a manufacturer's name to see the full list of their products accepted for use in the RoofStar Guarantee Program

* Use treated plywood over concrete deck surfaces

7 Fasteners & Accessories

An Accessory is a material that joins Primary or Secondary Materials together, or is connected to/with a Primary or Secondary material, but does not by its nature (apart from its installation) directly affect the waterproofing or water-shedding capabilities of the system. Accessories are not currently part of the Accepted Material program, but are listed here for reference to specifiers, designers and installers.

MembranesCoatingsJoints and Unions

These membranes are not Accepted for use in the primary waterproofing system, but may be use as for an ancillary function - for example, as protective membranes (a 'sacrificial' cap membrane).
