High Performance Fire Retardant APP Modified Bitumen Waterproofing Membrane With Composite Polyester Reinforcement
BITUTER FR Mineral is a selfprotected plastomeric waterproofing membrane, manufactured in an advanced continuous calendaring process by saturating and coating a composite carrier with a waterproofing fire-retardant compound made of a special grade of bitumen, modified with APP polymers and special FIRE RETARDING chemical additives.
While the APP polymers enhance the thermal, mechanical, and aging properties of the membrane compound, the mechanical characteristics of BITUTER FR Mineral are established by the composite carrier made of nonwoven Polyester armoured with Glassfiber filaments, which acts as the reinforcement that provides the membrane with the profound mechanical properties of the Polyester and the prominent dimensional stability of Glassfiber mats.
The upper surfaces of BITUTER FR Mineral is covered with colored mineral slate chips, with an 8cm slate free side margin for overlap welding, whereas the lower surface is laminated with a thermo-fusible polyethylene film.
BITUTER FR Mineral can be used for special roofing and waterproofing applications with fire-retarding property requirements & subjected to significant mechanical stresses and weathering conditions.
BITUTER FR Mineral is used as a single layer or as a top layer in an exposed multi layer roofing system for the following roofing applications:
- Exposed roofing in civil, industrial, and military works.
- Exposed re-roofing jobs on compatible substrates.
- Under roofing clay tiles on pitched roofs where tiles are fixed with mortar.
- Flashings for exposed up-stands in APP modified bitumen roofing systems.
