Index Fidia P & MS (mineral slate)
Reinforced Spunbound Polyester Elastoplastomeric Polymer-Bitumen Waterproofing Membrane.
Index Fidia P membrane is manufactured from a compound of distilled bitumen and polymers. After mixing, the characteristics of the polymers are dominant and are evenly dispersed throughout the matrix. Index Fidia P and Fidia MS have excellent stability at both high and low temperatures and possess good longevity.
The upper face of the membrane is treated with serigraph talc, which prevents problems when unrolling the product. The lower face is covered with a sacrificial polyethylene film and the roll is then embossed. The embossing assists in the rapid burn off of the polyethylene film in the torching operation and allows good vapour diffusion. Index Fidia MS has slate granules applied to the upper surface of the membrane during the manufacturing process.
Index Fidia P can be used as a single layer waterproofing system or as part of a multi-layer built up waterproofing system. The mineral surfaced Index Fidia P should be used as the upper membrane in a two layer system acting as a capping or weathering sheet.
