Application

Approved for use with Protan adhered, mechanically fixed or vacuum PVC single-ply membrane roof systems.

Description

Dual density mineral wool insulation boards approved and designed for use with Protan adhered, mechanically-fixed or vacuum PVC single-ply membrane roof systems.


Features and benefits:

  • Designed for use in warm flat roofs under adhered, mechanically fixed or vacuum Protan PVC single-ply membrane roof systems.
  • Produced with a robust, high-density top surface, the products exhibit point load compressive resistance.
  • Fast installation with fewer insulation fasteners.
  • Available in a wide range of thicknesses, offering single thickness solutions as well as multiple thickness options for greater thermal performance.
  • Dimensionally stable and can be cantilevered.
  • Fully tested systems designed for new-build and refurbishment applications.


Acoustic performance:

  • Excellent sound reduction and absorption performance.
  • Rain noise solutions.
  • Solutions to BREEAM Schools 2006.
  • System comprising of 1.2 mm single ply and a metal deck: 41–48 dB, 51.8–55.4 Lλ-dB Rain Noise Intensity. Consult manufacturer for further details.


U-Value:

  • Based on a system build-up with single ply 1.2 mm thick on a metal deck: 0.25–0.14 W/m²K.
  • The U values given are for guidance only. Please contact Protan for project specific data.
