RubberBond FleeceBack™ Single Ply

RubberBond FleeceBack™ is a 3mm thick polyester reinforced EPDM membrane, manufactured with Factory Applied Tape (FAT™).

FAT™ gives you a seam that has the same elasticity and flexibility as the membrane itself. Applied to our membranes in a factory controlled setting, FAT ensures reliable seams with greater peel and shear strengths than standard seaming methods.

The 3.05m wide roll with FAT™ reduces the amount of seams on the roof by 67% compared to felt systems and reduces the seaming time by 75% compared to other methods.

FAT™ is applied to one edge of the roll, the other edge has a guide line to ensure correct overlap widths and membrane placement.

FAT™ improves seaming productivity so projects can be completed faster, getting buildings ‘in the dry’ quicker and minimising business disruption.

SureEdge PVC Perimeter Trims

An alternative to using RubberBond Edge Trims, the benefit of these is that they create their own seal to the roof surface, negating the need to install a timber perimeter upstand.

The drip edge is a two part trim that securely clamps the membrane into place and creates a step into the gutter at the same time. The drip edge can also be used in conjunction with the Plastisol Trims. Internal and external corners for edge and drip trims.

RubberBond Plastisol Steel Edge Trims

Plastisol Steel wall trims offer a quick and economical alternative to lead and secured with RubberBoond RB Fasteners. Plastisol Steel perimiter trims feature a 10mm drip return on the bottom & are suitable for forming both drip & check kerb details. They are an economical method of finishing the roof perimeter.

Termination Bars are used to create a compression seal to upstands where cutting a chase isn’t possible. They must be used in conjunction with Water Cut-Off Mastic.

RIBA Product Selector

The Construction Products Regulation (CPR) has been adopted by the European Commission and UK Government from the 1st July 2013 to ensure that construction products meet the CE requirements of the new Regulation.

According to the Regulation, the requirement for CE marking will apply to:
“any product or kit which is produced and placed on the market for incorporation in a permanent manner in construction works or parts thereof and the performance of which has an effect on the performance of the construction works with respect to the basic requirements for construction works.”

So any flat roofing products that fall under this definition that are placed on the market from July 2013 and are covered by a harmonised standard EN 13956:2012 “Flexible sheet for waterproofing – Plastic and rubber sheets for waterproofing”, must be accompanied by a Declaration of Performance and will need to display the CE mark.

The Document of Performance (DOP) that accompany the CE-marking of the RubberBond FleeceBack EPDM membranes can be viewed or downloaded here.
