Product Description

Thermosash extruded and composite fin elements are custom designed to meet project requirements.

Our extruded and composite louvre solutions are able to be seamlessly integrated with our Thermosash suites - the brackets often do not require any secondary structure to support the shading or aesthetic devices, including downpipe brackets or signage - thereby maintaining a weathertight exterior. The integration has the added advantage of managing seismic differential movement amongst the building elements.

We manufacture at our premises in Auckland, Wellington and Christchurch and can custom clad the fin with almost any durable material.

Thermosash Solveil^TM Profiles

Our large variety of profiles provide design freedom
Standard sizes (width) range from 40mm up to 1200mm
Custom profiles can be engineered to meet your bespoke design requirements
The blade systems can be fixed or actuated via integrated BMS functions offering a high-quality external building shade system that can lower the heat gain on your building and add aesthetic value

Solveil^TM Support System

Thermosash provides a discreet engineered secondary support system to mount the Solveil^TM profile elements to the building facade to suit project and site requirements.

Low-Carbon Aluminium

Thermosash partners with a local NZ-owned extruder achieving a lower carbon footprint than the global average - offering reduced upfront carbon emissions. (find out more about our Sustainable Aluminium).

Aluminium is 100% recyclable, and the aluminium from our manufacturing process that is not powdercoated is environmentally managed back to our key suppliers and processed back into raw billet form.

Facade Optimisation and Sustainability Reports

To achieve optimised high-performance outcomes, we offer our clients the option of a Project Sustainability Analysis that covers different aspects of the full sustainability cycle. For more information view our Sustainability Facade Tools page.

Maximum Spanning Ability

Thermosash specifically engineers the best suite option for your project taking into consideration span, structural system, and environmental loads (e.g. wind). The spanning ability will vary depending on the above.

Warranty

The standard warranty is 10 years from the date of practical completion providing the subcontract includes fabrication and installation, and the maintenance schedule is adhered to.

Maintenance

It is recommended by almost all material suppliers that building washing should occur every 3-6 months to prevent environmental pollutants from corroding metals and to maintain the material warranties.

A full maintenance manual is provided on completion of a project for all the elements integrated within a project. Compliance to a maintenance schedule is essential to maintaining the quality of the installed product over time. Using Thermosash-approved facade maintenance contractor/personnel ensures the highest standards are met.
