ARMATHERM™ FRR STRUCTURAL THERMAL BREAK

Introduction

thermal-break

Armatherm™ Fabric Reinforced Resin (FRR) Thermal Break Pads deliver high performance thermal insulation between interior and exterior steelwork and / or concrete to prevent thermal bridging. Cutting out thermal bridging stops conduction heat loss and prevents surface condensation from forming inside the building that can be due to cold transfer meeting warm air. Armatherm™ Has been independantly evaluated and approved by the SCI (Steel Construction Institute.)

Washer and Bushing

With a bolt through insulation pad there is the possibility of a slight thermal transfer along the connecting bolt.

For the majority of installations this can be ignored, however this effect can be reduced with the addition of Insulation washers and bushing.

In extreme applications (e.g. Swimming Pools), to prevent condensation on the bolt head, a polyurethane nut cap can be supplied to effectively screen this cold surface from the internal environment.
