FlexiProof Fleece-Backed EPDM combines a 1.2mm extruded EPDM membrane with a 300gsm fleece fused to its underside. The embedded fleece helps the membrane bond, lie smoothly and bridge minor deck imperfections, making it especially relevant to refurbishment work.
Use fleece-backed EPDM when the specified system benefits from its thicker composite construction, strong bond and ability to accommodate minor surface irregularities. It is not installed with the same adhesive route as every one-piece EPDM detail.
Construction and performance
- 1.2mm extruded EPDM membrane with fully fused 300gsm fleece backing
- Overall construction more than 1mm thicker than standard EPDM membrane alone
- Puncture resistant and strong enough for normal installation foot traffic
- Elastic construction accommodates normal building movement
- Designed to cover minor roof-deck imperfections and reduce shrinkage
- Manufacturer-stated 50-year life expectancy and 25-year membrane warranty
- Manufacturer literature describes BROOF(t4), permanent UV stability and recyclable production
Where fleece-backed EPDM is useful
The manufacturer positions it for flat roofs of all sizes and particularly refurbishment projects. The fleece can help achieve a smooth finish over a prepared but imperfect substrate; it does not remove the need to make the deck sound, clean, dry and suitable.
Widths and full-roll planning
Forti Nova stocks the fleece-backed widths and full-roll configurations shown on the live product page. Wider or longer rolls are heavy: check access, lifting, crew size and the complete layout before ordering.
Adhesive selection matters
Use the FlexiProof adhesive specified for fleece-backed membrane and the relevant detail. Water-based deck adhesive, fleece-backed PU adhesive, contact products and primers are not interchangeable. Coverage also varies by substrate and application.

Frequently asked questions
What is the fleece backing for?
It provides a bonded textile underside that supports strong adhesion, smoother laying and better accommodation of minor prepared-deck imperfections.
Is fleece-backed EPDM the same as one-piece EPDM?
No. They are different constructions with different compatible adhesive routes and handling characteristics.
Can it go over an old roof?
It is particularly suited to refurbishment, but the existing build-up must still be assessed and prepared. Do not bond over a wet, loose, contaminated or structurally unsuitable surface.
Which adhesive do I need?
That depends on the substrate and detail. Use the exact FlexiProof product route stated for the selected membrane and contact Forti Nova if the deck build-up is uncertain.
Need project-specific help?
Forti Nova supplies the FlexiProof system with practical product support. Send your maximum roof dimensions, deck type and details such as upstands, outlets, rooflights and corners before ordering.
