Single-ply membranes

Thermal insulation for use with single-ply membrane waterproofing systems.


We manufacture PIR thermal insulation boards suitable for mechanically fixed and adhered single-ply membrane waterproofing systems across concrete, timber and metal flat roof decks.

Suitable for new build and refurbishment projects, our insulation can assist the specification of a single-ply roofing system by ensuring that risks such as ponding, condensation and wind uplift are minimised. Whether fastened mechanically, or with an adhesive, single ply waterproofing systems are the advantageous choice, particularly if weight and load is an important consideration. Created from strong and flexible membranes composed predominantly of synthetic polymer, single ply membranes are sealed at joints to form a continuous waterproof barrier and when combined with insulation and regular support, form complete, durable roof systems.

Each of our PIR boards features facing on both sides, the properties and characteristics of which are adapted to a flat roofing application. Available in a wide range of thicknesses, the high quality of our PIR insulation boards allow compliance with the latest BREEAM/Code for Sustainable Homes standards and Part L Building Regulation with thinner board sizes.

Our Powerdeck F, Eurothane Eurodeck, Plylok and Eurothane Silver boards are all suitable for this application.
