Firth HotEdge® has been developed to help improve the thermal performance of homes with concrete foundations and any cladding system.
The HotEdge® range of XPS insulation panels have been specifically designed and tested to work with RibRaft and X-Pod foundations. They are quick to install using standard building techniques and come pre-plastered to reduce finishing time (no plastering needed on site).
HotEdge® insulation is not just about R-values, it also helps close a building’s thermal envelope to reduce cold spots at thermal bridges between slab and timber framing. This reduces the chance of moisture forming which could otherwise lead to mould. This means a warmer, drier, healthier home.
These fully integrated thermal solutions are designed and independently assessed for proven performance specifically with Firth foundation systems to assist in attaining Homestar™ points and achieve compliance with NZS3604 and the H1, (5th Edition) updates.
Benefits of HotEdge® systems are:
- Quality
- Warmer and therefore more efficient and healthier homes
- Reduce/eliminates cold points at wall / slab junction created by thermal bridging (cold spots = mould spots)
- Proven R-values based on HotEdge® 3D thermally modelling
- Warmer and therefore more efficient and healthier homes
- Durability
- The robustness XPS compared to EPS means less waste through handling damage on site.
- XPS boards are more resistant to moisture.
- Support
- Dedicated systems technical support to answer any specifying or installation questions.
- Cost saving:
- Quick to install saving labour cost for builders and foundation specialists
- Free online design tools and BRANZ testing (ST18050) make it quicker to design with and specify
- Reduces build times through simple, standardised construction techniques.
- The pre-plastered surface helps reduce finishing time.
- Easy installation
- Uses standard construction method.
- Fits easily inside form work and with regularly space Tornado screws for a secure integration to the concrete slab.
- Fully compatible with all Firth’s RibRaft® systems: RibRaft TC3®, X-Pod® and other pod systems such as ClevaPod® .
Firth has developed online resources to help specifiers to easily calculate and design for slab foundation insulation requirements. These are free to use. The Firth online R-Value Calculator calculates an H1 R-value solution for your concrete foundation. WaffleSuite enables quick designing of RibRaft X-Pod® foundations for complex soil types and helps calculate a custom thermal solution for your project.
HotEdge® Extra® has a BRANZ test report (ST18050) for a 90mm framing bottom plate anchor solution that meets all NZS 3604 load requirements (>15Kn) for bracing systems e.g. Handibrac. Testing was done with 20MPa RaftMix concrete, M10 155mm ECKO screw bolts (orange top) and 12mm ECKO Packers.
