SOPREMA SYSTEM with thermal insulation

Soprema advices:

  • TPO membranes and thermal insulation: TPO membranes do not require a separating sheet. However, a geotextile (300g/m2) will reduce the spectrum of the thermal insulation panels (selfprotected roof) and / or in the case of expanded
    perlite, to avoid cleaning before hot air welding.
  • The positioning of drainage outlets implies a specific designing of the valley structure under water stagnation.
  • A 3% slope on the roof avoids water stagnation.
