RibRaft® HotEdge® – As easy as 1,2, 3 …

It’s common to get caught up with design aspects of your home that will affect how it performs, such as wall and ceiling insulation, double or triple glazing, cooling and heating systems etc. But what about the foundations?
Having a warm, dry and therefore healthy home is the desire of all homeowners as it is for architects when designing homes on behalf of their clients. And it starts with the foundations.
Firth’s RibRaft® HotEdge® is a fully integrated slab edge insulation system that will help achieve that warm cosy home and it’s as easy as … 1,2, 3 … because the hard work has been done.
Why choose RibRaft® HotEdge
“Our slab insulation products help architects and engineers achieve H1 compliance and more with their designs,” explains Wade Hargreaves, Senior Product Marketing Manager at Firth. “They can create warmer, drier homes for kiwis by eliminating cold spots at the slab/wall thermal bridge where moisture can form and lead to mould issues. We’ve developed free online tools to make it easier to specify our systems in their designs. These tools save time which means a cost saving for them.”
“We have a BRANZ tested (ST18050) bottom plate anchor solution with HotEdge Extra and 90mm timber framing, which achieved 15kN with 12mm packers and therefore meets common bracing system requirements. This gives architects, engineers and builders considerable confidence and peace-of-mind when specifying or installing our products.”
Tools to help:
- HotEdge R-value Calculator (for slab A/P ration design calculations)
- WaffleSuite (for more complex foundations designs with X-Pod)
- BRANZ Tested (ST18050) anchor solution for 90mm timber framing bottom plate.
- 3D Thermal Modelling to prove R-values for HotEdge and HotEdge Extra.
“We also have a dedicated technical support team to help architects and engineers with specific design and specification questions or swap-outs,” adds Wade. “This is a game changer for architects and engineers.”
Technical points to note:
- HotEdge®solutions are designed for use with all cladding systems to help designers/engineers achieve foundation compliance with H1.
- HotEdge (BV) for brick cladding and HotEdge Extra for non-brick
- BRANZ Tested (ST18050) bottom plate anchor solution for 90mm timber framing.
- 15kN achieved with 12mm ECKO plastic packers. i.e. meets HandiBrac requirements where other products don’t.
- Quality edge insulation for RibRaft slab foundations.
- Closing a building’s thermal envelope helps reduce cold points at wall/slab junction (cold spots = mould spots).
- HotEdge (BV) has been in the market for 5+ years.
- Proven effectiveness based on HotEdge 3D thermal modelling.
- Be wary of imitations that have not been tested or have verified R-values.
- Quick and easy to install (time/cost saving for installers).
- Compared to insulated, permanent formworks or products that need plastering.
- HotEdge Extra is 100% compatible with HotEdge (BV) for building designs that have multiple cladding types.
- Durable pre-plastered, extruded XPS slab edge insulations boards with ready-to-paint surface for reduced finishing time/clean up.
- Up to 10 x stronger than EPS, more resistant to moisture than PIR.
- Performs an aesthetic function by providing a tidy and paintable finished surface for concrete slab perimeters.
