Following Christchurch’s devastating earthquakes, for anyone who has any concerns or doubts about recladding with bricks, Caviteclad Thermashell may provide the answer.
Thermashell is a cavity-based external wall cladding system for residential and light commercial buildings where domestic construction techniques are used. Thermashell is classed as an Exterior Insulation and Finishing System (EIFS) and uses either 75mm or 90mm Neopor EPS panels as a plaster backing substrate to provide a lightweight, durable exterior cladding system. The system is fully BRANZ appraised and fully flashed using proprietary penetration flashings to create a dry cavity system. It’s installed by a certified contractors network and incorporates a primary and secondary means of weather resistance against water ingress. At only 9kg/m2 the entire system weighs less than 10% of the original brick veneer placing less stress and weight on the existing foundations.
Not only will Caviteclad Thermashell massively increase the existing thermal envelope of every dwelling to which it is applied (R=3.65 with R2.2 wall batt), but structural raking tests using EIF Systems have proven that the fixings used are able to move within the substrate. This will massively reduce the likelihood of future earthquake damage or settlement damage occurring in the cladding even in extreme circumstances.
