Eco-Torch - Insulation for flat roofs

EcoTherm's  5 in 1 flat roofing insulation board for use with any hot applied roofing system or adhered single ply system on metal, timber or concrete decks.


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-Torch is ideal for:

  • Torch on felt
  • Bituminous single ply membranes
  • Mastic asphalt
  • Roll and pour felt
  • Fully adhered single ply systems


EcoTherm Eco-Torch comprises a fibre free rigid polyisocyanurate (PIR) insulation core faced with coated glass tissue on one side and bitumenised glass fibre tissue with polypropylene fleece on the other. The insulation core is temperature tolerant and withstands the application of hot bitumen and asphalt to the surface up to 230°C.

Standard Dimensions

Length: 1200 mm
Width: 600 mm
Area: 0.72 m2
Thickness: 30 - 150mm*

* Requirements for thicknesses    over 140mm can be fulfilled with two layers of insulation boards.


Thermal Performance

The thermal conductivity (lambda/λ value) of Eco-Torch varies by
thickness as follows:

25 to 79mm = 0.026 W/mK
80 to 119mm = 0.025 W/mK
120 + mm = 0.024 W/mK

  • Energy Saving Trust Listed product

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.
