Flat roof insulation

EcoTherm offers a comprehensive, quality range of rigid flat roof insulation products. All our boards are backed up by rigorous quality assurance and plain English technical support.

Tackle heat loss where it matters most 
Up to 25% of a buildings heat loss is through the roof.  By using insulation with excellent thermal performance this will greatly improve the energy efficiency of the building, and in turn make meeting Building Regulations/Standards easy. 

EcoTherm in flat roofs: 
  • Ideal for both new build and existing roofs (replacing or refurb)
  • Lightweight boards will not weigh down the structure
  • Compatibility with variety of waterproofing systems
  • Easy to cut and transport on site due to the boards ridigity and light weight
  • Excellent thermal performance means thinner boards that will not add to overall building height


Eco-Torch can be used for new build or refurbished roofs, or for upgrading the thermal performance of existing roofs.

Tapered Flat Roof Insulation

A flat roof should always allow for water channelling and drainage to prevent issues such as ponding. Ponding can lead to premature failures in the waterproofing system and the need to refurbish an area or the entire flat roof before the end of its intended design lifetime. Standing water will promote the growth of plants, moss and algae and, in extreme circumstances, can add to roof loading and an uneven deck. These issues will only contribute to a drainage problem and over time could cause the roof to fail.  Installing tapered insulation also negates the requirement for a structural roof fall, helping to reduce the overall cost of the roof.

By creating appropriate falls and drainage, a flat roof is more likely to last for its designed life by channelling water to outlets efficiently. Tapered insulation is also ideal for existing roofs that may not already incorporate a structural fall. The boards can simply be installed on top of the existing waterproofing layer.
