Reinforced Plastomeric Bitumen Polymer Waterproofing Membrane made of Distilled Bitumen and Plastomers.

The Index VIS P membranes are available in 3mm and 4mm thicknesses on a 10m roll. The membrane manufacturing processes uses polymer modified bitumen reinforced with a composite reinforcement. This ensures a good quality membrane that has high elongation and stability across the defined temperature range. 

The upper face of Index VIS membranes are coated with a uniformly distributed, fine serigraphed talc, a patented treatment which allows the membrane to be unrolled easily during the application. 

The underside of the membrane is lined with Flamina, a sacrificial polyethylene film. It is embossed with small squares which assist in the rapid burn-off of the Flamina indicating the correct melting point for adhesion to a substrate ensuring a reliable installation. 

When the membrane is loose laid or spot bonded, the embossing diffuses the vapour. 

The Index Vis Polyester 4mm membrane can be used as a single layer system or as part of a multi-layer in both the refurbishment and new building works market. The Index Vis P 3mm should be used as an underlayer in a multi-layer waterproofing system.

Uses
  • On all sloping surfaces; flat, vertical and curved.
  • On different types of substrates: site-cast or pre-fabricated concrete substrates, on timber roofing and on the most common thermal insulation used in the building trade.
Intended use of “CE” Marking Specified according to the AISPEC-MBP Guidelines
