Fleeceback EPDM | SealEco RubberTopFleeceback EPDM is growing in popularity across the UK for both domestic and commercial flat roofing projects. To find out why, we’re taking a closer look at some of the biggest benefits of fleece backed EPDM and how such products are helping to improve sustainability across the roofing sector.

EPDM membranes have been popular all over the world for many years in the roofing industry. This is in part because of the unmatched durability and longevity EPDM has compared to other flat roof coverings.

Initially becoming common in the commercial and industrial roofing sectors, EPDM has since flourished for domestic roofing projects and is now fast-becoming the industry go-to single-ply roofing membrane.

What is fleeceback EPDM?

Fleece backed EPDM includes of a layer of polyester fleece, which is bonded onto the underside of the standard 1.14mm EPDM membrane. The overall thickness of fleeceback EPDM is then 2.3mm. The fleece backing is applied during the production process, but before vulcanisation to ensure the additional adhesion of the layers.

Why use a fleece membrane?

Insulating layers are advised in any green roof project atop the membrane and beneath the drainage layers. Fleeceback EPDM provides better puncture resistance with the additional fleece cushioning and is often the membrane of choice for green roof installers.

RubberTop fleece membrane is suitable for both adhered and mechanically-fixed installation methods with seam joins tackled using cold splicing techniques. This makes it a stable membrane over an expected lifespan of more than five decades.

Looking ahead to a sustainable future in the roofing industry

SealEco, the manufacturers of RubberTop fleece, has a goal to burden the environment as little as possible. This applies for the production, application and performance of the EPDM membrane.

EPDM is designed to be 100% recyclable at the end of its lifespan and gives off no toxic substances or fumes over the serviceable duration. This also makes it the ideal material for use in rainwater and surface water management systems, irrigation and conservation.

Using the latest technologies and techniques developed over time and investment, the EPDM can be split at the point of recycling to make new membranes, creating a sustainability that has been searched for within the industry for many years.

Why fleeceback EPDM is best for green roofing

Fleeceback EPDM for Green RoofingAs previously mentioned, fleece backed EPDM membrane provides the perfect base waterproofing layer for any green roof project. This is because it can be ballasted during installation due to the cushioning the fleece backing provides. The increased puncture resistance makes it one of the most reliable option for carrying the drainage layers in the green roof.

The high performance and reliability of EPDM membrane can bring peace of mind to green roof planners. The waterproofing layer is arguably the most important of all. A failed waterproofing membrane will mean stripping back all the upper layers, including planting and drainage, to repair or replace the waterproofing underneath.

Therefore, green roof projects need a highly reliable solution at the very base to ensure complete waterproofing over the entire lifespan of the green roof or the building underneath it. Fleece backed EPDM offers double the protection with its high resistance to root penetration over time as the planting layers mature.

Yes. RubberTop fleeceback EPDM is specifically designed to work with a range of existing roofing substrates due to the cushioning and extra adhesive qualities of the fleece backing. Perfect for timber, metal and concrete roofing.
