EPDM Rubber Roof Online Training Centre

CLASSICBOND® EPDM is CE marked with a nominal thickness of 1.2mm as opposed to the thinner 1.1mm of Firestone RubberCover as defined by EN 13956

Each roofing system has unique properties. With five Roofing Systems available; 4 EPDM Membranes and 1 Liquid Rubber, we are bound to have the perfect choice for your roof. Please checkout this overview of each to decide which is best for your project.

Yes, EPDM Membranes require the substrate to be dry prior to installation. This is so the the adhesive & primers can effectively bond the rubber to roof deck. EPDM products will not adhere to wet or damp surfaces. Trapped moisture may vaporize and negatively affect the performance of the membranes.

Each EPDM membrane roofing system can be bonded to a range of different surfaces. This article covers the various do's and don'ts for each roofing system, the surfaces that can be bonded to and the adhesives required.

Whilst bubbles or blisters on a once-piece EPDM roof can be unsightly they will not cause the rubber membrane to fail. These bubbles of trapped air/moisture can be caused by a variety of issues which are all avoidable if the roof design is correct and the membrane correctly installed.

Today more than 90% of the natural rubber supply comes from Southeast Asia. As rubber trees require a hot, damp climate they grow only in the “Rubber Belt,” an equatorial zone that stretches around the world. General purpose synthetic rubber has its origin in two gases: butadiene, a by-product of petroleum refining, and styrene, captured either in the coking process or as a petroleum refining by-product.

Yes! EPDM rubber membranes are not effected by cement or lime additives making them ideal for waterproofing screed decks

This article will help with choosing the correct adhesive for bonding EPDM to your roof deck

The Geotextile underlay can be used on top of the rubber membrane to protect it from sharp objects when it is planned to either ballast (cover) the membrane with pebbles for fire protection.

The biggest sheet size available in each system is as follows, all sheets can be joined where the roof size is bigger than the maximum sheet size: ClassicBond & Shedcover 1.2mm - 15.25m x 30.5m (50ft x 100ft) ClassicBond & Shedcover 1.5mm - 15.25m x 15.25m (50ft x 50ft) DuoPly 2.54mm - 1.52m x 12.20m (5ft x 40ft) RESITRIX 2.50mm - 1M x 10M (3ft 4" x 32ft 10")

You will typically need a standard 9" roller set, mini roller and brush for applying the adhesives and primers. A Seam Roller is a useful tool for tapes and joins and the RESITRIX system will require a heat gun for joins.

Yes you can install EPDM under a pitched tiled roof. This may be necessary on shallow pitched roofs to prevent leaks.

The first commercial rubber roof was installed in the United States in 1965 by Carlisle Syntec, it is now 50 years old and still going strong. This makes ClassicBond the only EPDM with a proven 50 year life expectancy!

Yes all of our EPDM membranes can be joined where the roof is bigger than the largest membrane size or where it would be easier to install the membrane in smaller sections.

This 20 year EPDM guarantee is available to all certified installers that have attended our training courses.

Yes to an extent. EPDM is designed to take LIGHT foot traffic during installation and for occasional cleaning or maintenance. If you require more use than this, i.e. for a balcony then there are additional materials that can be laid over your EPDM for a more durable solution.

ClassicBond and ShedCover = 1.2mm or 1.5mm RESITRIX = 2.5mm DuoPly = 2.54mm ClassicLiquid = 1.2mm in one coat

Yes it is possible to install slabs or tiles on top of an EPDM flat roof. There are a couple of options here depending on the type of slab or tile you plan to use.

Classicbond EPDM membranes are identical on both sides so there is no right or wrong side when installing. However you may sometimes find a small amount of writing printed on one side of the Rubber Membrane and it may be wise to keep this side down so an eyesore is not created.

If the pitch of your roof is too shallow for roof tiles and installing an EPDM rubber membrane can be an excellent solution to this problem

No The ClassicBond EPDM membrane is only available in a slate grey colour,

Yes, ClassicBond membrane holds the British Board of Agrément certificate, No. 11/4853 (issued to Flex-R Ltd). It also holds fire ratings for each of the thicknesses available.
