A single-ply roofing membrane made from polyisobutylene (PIB), with a prefabricated self-sealing selvedge and an integrated synthetic fleece backing.

Rhepanol® fk can be:

  • Mechanically fixed on flat and pitched roofs with the use of Gripfix strips.
  • Loose laid and ballasted waterproof layer for flat roofs.
  • Partially bonded waterproofing layer on flat and pitched roofs with limited access using Rhepanol® Adhesive 90.

A range of prefabricated shapes for the treatment of details and flashings is also available.

The system is installed by approved FDT Ltd contractors.

Rhepanol® fk is available in 10 and 15 m rolls.

Installation:

– Mechanical fastening:

Rhepanol® fk is rolled onto mechanically fastened Gripfix strips, providing optimal wind load distribution and securing the membrane permanently to the roof. Movement-related stresses within lower layers of the roof are not transmitted to the membrane, preventing damage.

Suitable substrates include:

  • Profiled steel decking;
  • Reinforced concrete;
  • Lightweight concrete.

A vapour control layer, such as Vapour Barrier fk, and EPS, rigid urethane foam or dense mineral wool board should be laid over the substrate. EPS or rigid urethane insulation should be overlaid with a separating layer such as Fire Retarding Layer fk.

– Loose laid:

The roofing membrane restrained against wind uplift forces by ballast. The membrane is separated from the other layers of the roof build-up so movement and stresses in the supporting structure are not transferred to the membrane.

Suitable substrates include:

  • Reinforced concrete;
  • Lightweight concrete.

A vapour control layer, such as Vapour Barrier fk, and EPS or rigid urethane foam should be laid over the substrate. An upper protective layer, such as Protection Sheet TS fk should be used where the ballast will consist of paving slabs over a gravel bed.

– Bonded:

Bonding Rhepanol® fk roofing membrane using Rhepanol® Adhesive 90, ensures the maximum possible mobility of the roofing membrane. The membrane is securely bonded to the substrate by applying adhesive stripes, a minimum of eight per metre

Suitable substrates include:

  • Profiled steel decking;
  • Reinforced concrete;
  • Lightweight concrete.

A vapour control layer, such as Vapour Barrier fk, and EPS or rigid urethane foam should be laid over the substrate.
