RibRaft® HotEdge®

Product Description

RibRaft® HotEdge® system is a fully integrated slab edge insulation system that assists in attaining Homestar™ points.

Unlike ‘bolt-on’ alternatives, RibRaft’s HotEdge® is placed inside your RibRaft® foundation boxing before Firth RaftMix® concrete is poured. Evenly spaced tornado screws ensure HotEdge® is structurally integrated within every floor slab, creating a seamless finished foundation system for the homeowner. There are 3 heights available for clad, veneer and 300mm RibRaft® Pod. 

The RibRaft® HotEdge® System has been designed specifically for Firth RibRaft® floors using Firth RaftMix® concrete.

Unique features of the system are:

  • The system highly resistant to moisture, retaining its R-value year after year, and is extremely strong and durable (up to 10 times stronger than expanded polystyrene insulation - EPS
  • With the RibRaft® HotEdge® system you don’t need to increase the framing size in your design: standard 90mm framing applies
  • The system is fully compatible with Firth’s RibRaft EQ® and RibRaft TC3® foundation systems
  • The system has been specifically 3D modelled by BRANZ
