Techno EPDM

Firestone RubberCover EPDM is a 100% cured single-ply roofing membrane made of a synthetic rubber Ethylene-Propylene-Diene Terpolymer. Since 1980, more than 1.000.000.000 m² of Firestone EPDM membranes have been successfully installed on commercial, industrial and residential roofs worldwide. 

The average (20m2) rear extension should only take a morning to install. Getting the roof stripped off and any decking replaced if needed usually takes longer than installing the Firestone RubberCover EPDM.

Water-based adhesive is to be used on timber substrates. Contact adhesive (solvent-based) can be used on most other substrates but not foam insulation boards.

We recommend a ply faced insulation board, for example, Kingspan TR31 or similar. Alternatively, you can insulate on top of the decking with foil-faced boards, then overboard with OSB or plywood, secured with long screws.

Our contact adhesive can be used for this type of application but, unlike our water-based glue, this is quite tricky to do on large areas. We strongly recommend over boarding roofs with a minimum of 12mm ply or OSB and using water-based glue.

No.

Ponded water, snow, frost and ice must be removed from the roof surface before installation of the membrane. Water-based adhesives can be applied to a damp substrate.

The roof can be accessed for periodical maintenance. 

We provide a 20-year membrane warranty. 

Yes, it is possible to cover the membrane with gravel pavers but the membrane must always adhere to the substrate. Firestone recommends the use of a protective geotextile (polyester 300 g/m²) between the membrane and the ballast.

Firestone Bonding Adhesive and Firestone QuickPrime Plus can only be used in well-ventilated areas. Both products must be kept away from ignition sources. Do not smoke when using. Firestone recommends wearing gloves when applying Firestone QuickPrime Plus. For further information, please consult the Safety Data Sheets and/or the information shown on the product labels.

The use of double-walled penetrations is required.

Firestone QuickPrime Plus primer must be used with ALL Firestone QuickSeam products to clean and prime the membrane before application of the QuickSeam products.

No, except when the membrane is extremely dirty, in which case it must be cleaned with water and a clean rag.

The coverage rate is 1 litre per 2 m² (two-sided).

Yes.

The minimum temperature required for application of RubberCover™ Bonding Adhesive is + 5°C and the maximum humidity is 80 %.

The surface must be clean, smooth, dry, and free of sharp and/or loose objects and/or foreign materials such as oil, grease, and/or other contaminants. Therefore, it is recommended to sweep the substrate with a brush before the installation of the membrane.

No.

The membrane is only available in black.

Yes.

The membrane can be easily repaired with a piece of Firestone RubberCover QuickSeam Flashing.

Yes.

Contact with mineral and vegetable oils, petroleum-based products, fresh bitumen, and grease should be avoided.

No specific maintenance is required for a Firestone RubberCover EPDM roofing system. However, Firestone recommends a yearly inspection of the roof.

Firestone RubberCover EPDM membranes offer unmatched resistance to UV radiation, ozone, alkaline rains and high or low temperatures. Recent studies show that the membrane has a life expectancy of more than 50 years.

No, the Firestone RubberCover EPDM membrane is resistant to UV and ozone.

No, there is no difference between the top and bottom of the membrane.

Yes.

EPDM is an inert material with limited environmental impact during both the manufacture and installation process.

Sedum vegetation can be placed over the RubberCover EPDM membrane, provided that a root resistant geotextile is used between the vegetation and the membrane. A distance of 30cm must be taken into account between the vegetation and every roof installation detail.
