Proofex Torchseal A300

Polyester fabric-backed base sheet, for heat sensitive substrates in multilayer torch-on bitumen membrane systems.

Typical Applications

  • Used as a base sheet over timber or thermal insulation and may also be applied over old failed membranes

Advantages

  • Uniform thickness factory controlled in manufacture
  • Excellent cold flexibility -10°C
  • The polyester fabric creates a micro air- space between the membrane and the substrate through which vapour may easily escape
  • Manufactured with a selvage edge for overlapping purpose providing a continuous waterproofing barrier against water ingress
  • Flexibility at low temperature (EN1109) : -10°C
  • Impermeability to water (EN1928 B method) : ≥ 60 kPa
  • Longitudinal Tensile elongation (EN12311 1) : 45%
  • Longitudinal Tensile strength (EN12311 1) : 650 N/50mm
  • Thickness /Mass : 1.8kg / m²
  • Transverse Tensile elongation (EN12311 1) : 45%
  • Transverse Tensile strength (EN12311 1) : 500 N/50mm
