Typical walls in New Zealand construction have insulation that is installed between timber (or steel) framing which results in a high level of thermal bridging with an associated reduction in wall R value performance.
The Technoform Thermal Isolator is a mechanical anchor that connects the cladding to the building's structure. Three different depths of clip; 50mm, 75mm and 100mm, are available to suit different insulation thicknesses and R value requirements.
The isolator is made of a low conductive material and is spaced vertically and horizontally (non-continuous) so it does not thermally bridge the external insulation.
The intended purpose:
The Technoform Thermal Isolator can be used in any wall application where external mineral wool insulation is required, which includes:
The Thermal Isolator Clip is an engineered mechanical fixing system that facilitates the connection of facades to the building structure whislt allowing external insulation of various depths to be used and not compromised by compression or multiple fixing penetrations. The clips have been engineered for specific dead and live loads therefore no clip substitutions are possible without re-engineering the structural performance outputs.
The number of clips required for a given cladding weight and wind exposure zone is based on multiple factors including fastener pull out, substrate strength, fastener strength, accurate installation following fastener manufacturer’s guidelines and requirements. The clip is installed by a suitably qualified tradesperson and does not require further specialised training.
There can be no substitution of fastener without re-engineering the structural performance outputs.
Where any cladding system is specified, care must be taken to use the highest clip frequency required by the cladding system or the spacings required for other factors such as wind load which may overrule the minimum cladding fixing requirements. Compressive strength of the substrate should also be taken into consideration to ensure suitability for loading. The clip frequency calculator available from Technoform Asia Pacific Pte Ltd (NZ Branch) takes these factors into consideration.
The Technoform Thermal Isolator has been independently reviewed and tested and is deemed to comply with the NZBC in relation to:
