Drainage Mat

Synthetic drainage and ventilation layer — Kingspan Thermakraft Drainage Mat is an extruded three-dimensional synthetic black mesh measuring 7mm thick. The product provides an uninterrupted drainage path and ventilation between the roof cladding and roof underlay.

Drainage Mat is made from polypropylene plastic. Its strand entanglement is designed to withstand compression on forces caused by typical roof fixings.

Key Features
  • Drainage Mat comes in one roll size: 1370mm wide x 18.3m long (25m² coverage)
Scope of Use

Suitable for use under long-run steel roofing where specific drainage and ventilation path is required.

As a secondary function, the product may be used for retro fitting walls when a cavity is required between the wall cladding and the wall underlay/insulation material. Note, specifiers and designers must assess the suitability and compatibility of Drainage Mat for their specific retro fitting project.

Limitations on Use

  • Must NOT be used under translucent sheeting
