Alsan® FLEECE Flashing

Alsan® Voile Flashing is a flexible and elastic reinforcement made with a polyurethane foil between two polyester fleeces, to be used with Alsan® Flashing and Alsan® Flashing Jardin waterproofing systems.


Alsan® Voile Flashing improves tear strength, puncture resistance, flexural fatigue and capabilities of crack bridging while maintaining membrane uniformity to be conform to any shape, irregular penetrations and other surfaces. It has excellent coating saturation capabilities into elastomeric polyurethane resins.


- high tear resistance,
- light and flexible,
- waterproof,
- quick and easy use,
- constant quality,
- secured,
- without any flame.


Mix and apply Alsan® resin in strict accordance with SOPREMA instructions. Apply mixed resin liberally to the prepared surface with a roller using a broad, even stroke. Roll out the polyester fleece onto the liquid resin, making sure that the roll is unrolling smooth and without any wrinkles or fish mouths. Alsan® Voile Flashing will begin to rapidly saturate with the liquid resin. Allow the fleece to saturate with resin from bottom up. Using a roller, wet the fleece with resin applying light pressure. Use a medium nap roller to eliminate any air bubbles, wrinkles, etc. Apply additional liquid resin mix on top of fleece until fully saturated and the layer of resin is fully and evenly applied. The coat should be smooth and uniform.
