Lose height, gain value

Developed by Radmat’s roofing experts to solve regularly occurring challenges created by the drive for more thermally efficient buildings, safer access and more external space, the ProTherm  Quantum® PLUS+ VIP Inverted Roof Insulation System enables architects to dramatically reduce the depth of a finished floor system; providing the solution to counter low upstands against the increasing thickness of traditional Extruded Polystyrene and Expanded Polystyrene products specified in order to meet more stringent thermal demands.

Where is it best used?

On roof terraces, enclosed balconies over heated space and insulated walkways in an inverted roof construction where there is a requirement for thermal performance, and insulated areas where depth is critical to the overall construction.*

What can it help to deliver?

  • Part L compliance: Exceptional thermal performance
  • NHBC Chapter 7.1 compliance: Insurance and warranty requirement of 75mm threshold achievement
  • Approved Documents B
