The Rubberall Reinforced Perimeter Strip (RPS) Linear Metre also referred to as Reinforced Universal Secure Strip is a 150mm reinforced strip of EPDM. This EPDM rubber bonding tape is used to secure upstand details.
- Like most single ply membranes, EPDM rubber membranes will try and shrink over time. By mechanically fixing a Reinforced Perimeter strip at all upstands, it is possible to reduce the opportunity for the EPDM membrane to pull away from the upstand detail. The 6″ Reinforced Perimeter Strip Linear Metre will make sure the EPDM is secure.
How does it work?
- The Rubberall Reinforced Perimeter Strip has a bonding tape pre-applied along one edge.
- This bonding edge is chemically welded to the underside of the EPDM using the Seam Tape Primer.
- This ensures that the EPDM membrane does not require puncturing during installation.The Rubberall Reinforced Perimeter Strip may be fixed using fastening plates. Alternatively, a Rubberall Termination Bar, with the appropriate fasteners for the substrate you are fixing to, may be used.

Preparing and cleaning the roof surface prior to insulation is crucial.
Do you know all the steps to roof surface preparation?
- EPDM roof membrane will adhere to certain isocyanurate insulation boards compatible with our adhesives.
- EPDM roof membrane adheres to plywood, OSB (Oriented Strand Board) and 13mm high-density wood fibreboard and concrete.
Polystyrene insulation should not adhere directly to EPDM rubber membrane. If polystyrene insulation is used, cover insulation with 13mm high-density wood fibreboard. Butt all insulation boards together, staggering all of the joints. Any spaces larger than 6.5mm of 25.4mm must be filled to provide a uniform, smooth surface.
- Screws and deck plates should be applied at the minimum rate of 8per 4ft x 8ft sheet of insulation, and 5 per 4ft x 4ft sheet or as required by the insulation manufacturer.
When installing insulation around the perimeter, the fastening pattern is 1 screw and 1 deck plate every 0.61mtrs (that is 16 per 1.22 x 2.44mtrs). Examples of fastening patterns are shown in the photo.
NOTE: Extra fasteners should be installed around protrusions such as pipes, chimneys, skylights and irregularities in the roof deck.
- Do not install more insulation than can be covered with EPDM membrane by the end of the day.
- Reroofing over a wet substrate is not good roofing practice. All wet material should be removed and replaced.
Therefore, the roof surface must be dry as moisture will cause poor membrane adhesion and blistering.
6. The roof surface should be swept to remove dirt, dust and other loose particles.
7. Good roofing practice dictates that the roof surface must have positive drainage of at least 3mm in 30.48cms.
