Actis Hybris


Honeycomb multi-foil insulation for pitch roofs, ceilings, timber frame and masonry walls and suspended timber floor applications

An innovative and unique insulation product providing excellent thermal performance.

Works by reflecting radiant heat using the outside reflective layers while the inner core elements reduce heat loss through conduction and convection methods.

Also controls air and vapour movement.

Highly durable, does not create thermal bridging by sagging, shrinking or deforming.
