Fully-adhered Roofing Systems

EPDM membrane shall be fully-adhered to the substrate with Carlisle 90.8.30A Bonding Adhesive. Adhesive must be applied to both the membrane and the surface to which it is being bonded. Adhesive can be applied on dry and clean surfaces such as concrete, wood, aged or new asphalt membranes. Always apply bonding adhesive on both sides and roll the lap with a steel or silicone roller, applying positive pressure and creating an even layer of bongin on both sides. Furthermore, always provide additional membrane securement with Carlisle Russ strips at any angle change and all terminations.

Mechanically-Fastened Roofing System

In a mechanically-fastened system, the horizontal level is mechanically fastened. The number of fasteners depends on the wind uplift requirements. Wind uplift is influenced by different elements:
  1. The roof is always divided up in different areas:
    • Central area
    • Edges
    • Corners
    • Other turbulent areas
  2. The building:
    • Height
    • Length
    • Width
  3. Location of the building:
    • Coast
    • Countryside
    • Urbanised or forested
    • City
These details determine the number of fasteners. Starting point is always that turbulent areas, corners and edges will be better fastened than middle part. The higher the builing, the better the flange must be fastened. In this system, vertical layers are also fully-adhered with Carlisle Bonding Adhesive 90.8.30A. The adhesive always must be applied to both sides! Apply adhesive evenly without globs or puddles to achieve continuous coating of both surfaces! Also install Carlisle Russ strips at every angle change and all flashings. This mechanical system allows work on any dry and dust free substrate. The specific characteristics of the substrate require attention: compression resistance, brittleness temperature, longevity and thermal stability. Attention will evidently be made to pullout values/withdrawal resistance criteria for required fasteners in the different substrates: (steel, wood, structural concrete and cellular insulating concrete). If you want to be absolutely sure about the maximum wind uplift resistance on your roofing system, our services can conduct on-site test to determine actual pullout values!

Ballasted roofing system

(fire reaction class A1!!)
In case of a ballasted roofing system, membrane will be loose-laid and attached to the substrate merely by placement of ballast. Ballast type depends on specifier´s and WTCB/CSTC-requirements, taking into account wind uplift charges. At the perimeter of the roof level, securement must be provided with Carlisle Bonding Adhesive 90.8.30A. Always apply adhesive on both mating surfaces! Thoroughly roll bonding adhesive to achieve an even coat of adhesive on both mating surfaces! Also always provide additional securement with Carlisle Russ strips at every angle change and all flashings. Structure must evidently be capable of bearing the weight of the selected system. We strongly suggest placement of a non-woven polyester protective mat in places where sharp parts-if any-might dammage Carlisle EPDM rubber.
