About this service
Internal Wall Insulation
Where external insulation is not possible (listed buildings, conservation areas, tight boundary lines), Internal Wall Insulation (IWI) delivers excellent thermal performance from inside. We install PIR rigid boards or mineral wool stud walls, carefully sealing all junctions to prevent cold bridging. Our team coordinates all associated second-fix work including re-routing sockets, switches and radiator brackets, leaving the room ready for decoration with minimal disruption.
