Carbon reduction

Single ply can make a significant contribution to carbon reduction in three ways:

Simple, durable, highly insulated roof assemblies

Easy integration with energy capture equipment such as photovoltaic, solar heating and wind lower

As a reliable, durable base for green roof systems

For example, a warm roof system of just 210mm thickness could achieve a thermal transmittance (U-value) of just 0.15 W/m².K Modern fastening methods avoid cold bridges and simplify the installation process, enabling increased insulation thicknesses (reduced U-value) in new build or as an overlay to the existing in refurbishment.

Single ply roofs can be integrated with a range of energy capture equipment, which can be sited at roof level so as to minimise visual intrusion, maximise exposure to solar radiation and wind. Options include support rafts and frames to which equipment can be mounted, allowing change without affecting roof integrity and photovoltaic panels integrated with membranes.
