Eco-Deck - Insulation & decking for flat roofs

Tough, structural, pre insulated thermal roof decking for flat roofs.  Deck and insulate in one simple application.


Suitable for use in new build or upgrading the thermal performance of existing roofs, providing a cost effective means of reducing CO2 emissions and compliance with Building Regulations/Standards.

Eco-Deck can be used in combination with the following waterproofing systems:

  • Single ply mechanically fixed
  • Single ply adhered
  • Mastic Asphalt
  • Roll and Pour Felt


EcoTherm® Eco-Deck comprises a fibre free polyisocyanurate (PIR) insulation core faced with tough, exterior grade plywood used as pre-insulated foil-backed thermal insulating decking for flat roofs. It is ready to fix and finish using basic tools and traditional roofing techniques.

Eco-Deck benefits:

  • Insulate and deck in one application
  • Meets the thermal requirements of the Building Regulations/Standards with minimal thickness
  • Timber facing is compatible with most BUR membranes
  • Large format boards cover areas quickly
  • 'Cut-and-cover' operations can be carried out faster reducing the 'open time'
  • The manufacturing facility, at which EcoTherm Eco-Deck boards are produced, carries FSC® (FSC®- C109304) certification.

Tapered insulation roof schemes create falls on flat roofs, reducing the risk of water ponding by channeling water to drainage outlets.  They offer time and cost saving advantages over other means of creating falls and often eliminate the need for structural falls.  To find out more speak to our tapered insulation partner Building Innovation Ltd.
