Product Description

Triso Super 10 Plus thin thermo-reflective insulation is ideal for pitched roof, over rafter, under rafter, attic conversions and dormer applications. In an over-rafter application, Triso Super 10 Plus has the specific advantage of minimising the height of the roof line, due to the relative thinness of the construction.

The product is only 35mm thick, and is thermally equivalent to 210mm of mineral wool. Triso Super 10 Plus is designed to be airtight, water tight and water vapour resistant. It acts as a barrier against cold air infiltration and prevents warm air escaping.

Installation guide

  • Ensure an air gap of 25mm minimum on either side of the insulation.
  • Felted roof : ensure an air gap of 50mm minimum between the insulation and the felt with ventilation from eaves to ridge according to British Standards.
  • Pull the insulation taut and staple every 50mm to the rafters or timber support using galvanised staples, 14mm minimum. 20mm stainless steel staples are recommended.
  • Overlap the insulation 50mm to 100mm at each joint and staple every 50mm onto the rafter or timber support batten.
  • Cover all joints with Actis isodhesiv reflective tape to give an air tight finish.
  • Fold all finishing edges under by 50mm minimum, staple every 50mm and secure with final batten.
  • All exposed edges must be sealed with reflective tape to prevent ingress of moisture to the inner layers of the insulation.
