Multi Layer Foil Insulation

Space saving multi-layer foil insulation from Web Dynamics and Actis.

A different way of looking at insulation

Multi-layer foil insulation is a relatively new technology that has taken a different direction in terms of how we insulate our roofs. Traditionally, higher thermal performance levels have been achieved by putting more and more PIR insulation or quilt type products in between the voids of rafters. Multi-layer foil insulation reduces the thickness of these other types of insulation that are needed whilst also providing an airtight finish therefore eliminating cold-bridging.

How do they work?

They are made from internal and external layers of reflective film which reflects thermal radiation. These layers are then separated with foam wadding which create a barrier against the transmission of cold or heat.

With their multi-layered make-up, they act against all types of thermal transfer simultaneously.


Whether you choose the Thinsulex TLX Silver or the Triso-Super 10, you can be confident that you are getting a product that has been rigorously tested to all the relevant European Standards where applicable. Details of such tests can be found on the links within the product page details.


Multi-layer foil insulation is most commonly used in roofs, both under and over rafter application but is also used in walls.
