The intended purpose:

• Thermally isolates the building's cladding from the structure
• Reduces heat flow through the building's envelope
• Moves the dew point outside the building's structure
• Can be used where fire compliance is required
• Can be used where acoustic performance is required

The Technoform Thermal Isolator can be used in any wall application where external mineral wool insulation is required, which includes:

• Residential buildings: detached, semi detached, medium density housing and apartments
• Commercial buildings: Hotels, hospitals, aged care, schools and offices 
• High rise buildings: Facades

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:

• H1: Energy Efficiency
• B1: Structure
• B2: Durability
• E2: External Moisture
• E3: Internal Moisture

• Glass fibre reinforced polyamide has been used in thermal break facade applications for 50 years globally and 13 years in New Zealand
• Aluminium bracket systems have been used in facade applications for decades
• Mineral wool external insulation has been used in facade applications globally for decades
