What is Firestone Rubbercover membrane?2020-01-22T14:21:50+00:00

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 square metres of Firestone EPDM membranes have been successfully installed on commercial, industrial and residential roofs worldwide. Various roll sizes, the biggest being 15m wide and 61m long.

Does the membrane have an up- and downside?2020-01-22T14:23:07+00:00

No, there is no difference between the top and bottom of the membrane. On fire-rated (FR grade) membrane, there is clear wording stating which side this membrane should be laid.

How long will the membrane last?2020-01-22T14:24:18+00:00

The membranes offer unmatched resistance to UV radiation, ozone, alkali rains and high or low temperatures. Recent studies show that the membrane has a life expectancy up to more than 50 years, even when exposed to sunlight.

Will the membrane require any protective coat?2020-01-22T14:29:30+00:00

No, the membrane is totally UV stable and requires no chippings, ballast or solar reflective paint.

Is one-sided application of the membrane sufficient?2020-01-22T14:30:23+00:00

Bonding adhesive must always be applied to both surfaces. Water-based adhesive can be applied to either to the substrate only (wet mate method), or using the two-sided contact method, i.e., both to the underside of the membrane and the substrate, depending on various
factors like weather conditions. Please refer to the “Installation Guidelines for Modular Water
based Adhesive”.

What are the coverage rates for the adhesives?2020-01-22T14:31:28+00:00

Approximate figures are as follows:

Bonding adhesive is 2 sq. metres per litre.
Water-based adhesive (two-sided application method) is 2 sq. metres per litre.
Water-based adhesive (one-sided wet mate method) is 3 sq. metres per litre.

Must the membrane be cleaned before applying Firestone QuickPrime Plus?2020-01-22T14:31:59+00:00

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

Is the installation of the membrane weather dependent?2020-01-22T14:33:31+00:00

Yes, the minimum temperature for application of the adhesives is +5ºC and the maximum humidity is 80%. If the temperature is likely to drop below freezing during the following 48 hours after application, Firestone Bonding Adhesive must be used instead.

I’m a roofer, what are the benefits to me?2020-01-22T14:34:42+00:00

Well, there are a few benefits.

  • It is cold applied, reducing your public liability insurance.
  • Its a really quick install time, great when there are restricted weather gaps
  • Strong global branding
  • 50 Years life expectancy
  • Large seamless sheets, up to 12m x 30.5m We also have some rolls upto 61m long. In 1 Piece.
Can EPDM be used for green roofs?2020-01-22T14:35:11+00:00

Yes, perfect for green roofs. Most residential roofs have no joints, so nothing to fail. Even large commercial roofs can have little or no joints. We do recommend a root barrier with green roof installations.

Where are you based?2020-01-22T14:36:08+00:00

We operate from Derby, nicely central to all of the UK. We operate from 24,000sqft of warehousing, and distribute next day to almost any UK address.

What is Firestone Rubbercover?2020-01-22T14:36:48+00:00

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 square metres of Firestone EPDM membranes have been successfully installed on commercial, industrial and residential roofs worldwide. Various roll sizes, the biggest being 15m wide and 61m long.

How can the membrane be repaired in case of damage?2020-01-22T14:37:37+00:00

For flat areas, the membrane can be easily repaired with a piece of Quickseam SA flashing. For damage at angle changes, a Quickseam Corner Flashing patch must be used instead.

Is the membrane available in different colours?2020-01-22T14:38:12+00:00

No, the membrane is only available in slate grey. We do however supply an acrylic paint in grey or white which can be used.

Which substrates can I adhere the membrane to?2020-01-22T14:38:45+00:00

Either OSB3 sterling board or plywood timber, but smooth concrete and tissue-faced insulation boards are also suitable. Note that new concrete should be fully cured before membrane installation and this takes a minimum of 28 days.

Are any precautions required during installation?2020-01-22T14:39:12+00:00

Both Bonding Adhesive and 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 using QuickPrime Plus. For further information, please consult the Material Safety Data Sheets as well as the information shown on the product labels.

Can I walk on a Firestone RubberCover EPDM roof?2020-01-22T14:39:42+00:00

Yes, the roof can be accessed for periodical maintenance, but take care to ensure no sharp objects (e.g., small stones) are attached to the underside of footwear. In case of regular foot traffic, the membrane must be protected with a walkway, e.g., pavers placed on protective rubber feet.

Is there a warranty for Firestone RubberCover EPDM membrane?2020-01-22T14:40:08+00:00

Permaroof UK provides a 20 material-only warranty for installations carried out by Permaroof trained contractors. Please refer to the warranty section for further information.
