KRAITEC® beneath PV systems

Requirements for protection systems beneath PV systems and reasons for them

  • Protection system for sealing sheet: For protecting high-quality seals from mechanical damage.
  • Tested fire behaviour: for providing protection from fire
  • Frost-resistant: For protecting the layers beneath from the effects of the weather.
  • Rot-proof and waterproof: For providing long-lasting protection.
  • Integrated separation layer in the event of incompatibility (KRAITEC top PV and KRAITEC top plus): For ruling out incompatibilities between sealing sheet and building protection mat
  • Kinetic coefficient of friction: For a firm footing and against uncontrolled movement of the elements on the sealing sheet
  • Elastic: Adapts to subsurface and minor undulations
  • Quick and easy to put down: Without heavy equipment in order to keep costs down

Solutions with KRAITEC®

  • Protection layer in accordance with DIN 18195 part 10
  • In accordance with DIN EN 13501-1 Efl (in accordance with DIN 4102, B2)
  • Frost-resistant and water permeable due to open granular structure, no puddle formation.
  • Rotting and dissolving by water are prevented by using specified recycling rubber granulates.
  • Easy loose and quick laying technique, easy cutting by using strips
  • The fleece and composite film lamination on the back prevents plasticiser from migrating between the building protection mat and the sealing sheet
  • KRAITEC top PV also has a separating layer and a friction-supporting layer because of the compound film. (µ ≥0.6*)
  • Because of the elasticity of the products, they adapt to the subsurface and undulations. Complicated cutting can be avoided in this way.
