PW1000 TI-160 Thermally Improved

Product Description

Thermosash PW1000 TI-160 : Thermally improved four sided mechanically glazed engaged curtainwall - both horizontal transom, and vertical mullion elements are expressed.

Mullion Size: 160mm


We custom design all our suites to suit our projects to maximise the efficiencies within the suite and often to incorporate added elements or unique building structures, building movements or floor heights.

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 all aluminium from refurbished sites and from our manufacturing process is environmentally managed back to our key suppliers and processed back into raw billet form.


Our systems are prefabricated and glazed in a factory environment, stored if necessary, and transported for just-in-time site delivery. We have highly skilled installation teams who work safely and effectively to close in buildings rapidly.

High performance facade solutions

Our team of designers and engineers are able to review your project and advise around the best solutions, taking into consideration environmental factors, sustainable outcomes, code compliance and budgetary requirements.

Performance Efficiency

High performance buildings are looking to be further energy efficient and are seeking greater Thermal performance through improved suite sections. Thermosash's Thermal Break series offer this solution - providing not only much improved reduced transmittance of heat load and heat loss - but exceeding industry codes on air filtration which is a significant component of building heating and cooling efficiencies.

The final performance of the curtainwall / panel wall suite is subject to many variables, from size of individual panels, glass performance, introduction of transoms and integrated solar shading (where bracketing may cause a cold link passage) and spandrel depth (insulation).

It is important to note that the aluminium section alone does not provide the thermal performance often expected. Glass specification is a significant contributor to the overall mechanical performance requirement of a building. The larger the glass pane the better performing the panel will be on average.


The standard warranty is 10 years from the date of practical completion for these products. This covers workmanship and weather tightness, providing the subcontract includes fabrication, installation and glazing of all components, and the maintenance schedule is adhered to.


Maintaining glass, metals and stone are all particular to the environment that they are placed in: eg. marine, environmental pollution, exposure to natural washing, etc.

It is recommended by almost all material suppliers that building washing should occur every 3-6 months to prevent staining to glass and 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.
