What we do

Our design teams work alongside the client, architects and engineers providing critical technical specialist expertise from concept to completion. We design and detail to meet the project’s demand for seismic risk, wind loads, climate zones, corrosion zones and building importance levels as well as aesthetics, unique site constraints and budgetary requirements.

We have the knowledge and expertise to assure a compliant, buildable, warrantable and high-performance facade solution that cohesively integrates our curtainwall, aluminium windows & doors, solar shading, rooflights and other facade products into your project.

The real value of a building facade is measured by its long-term durability and performance.  This value is gained through early strategic decision making and expert production and installation. We offer and advocate for early contractor involvement so that we can partner with you on your project to reduce risk and deliver value driven long-term outcomes. 

Thermosash offers a totally integrated service for early sub-contractor involvement (ECI or ECE Engagement) - we are here for you:

• Let us manage the facade risk and identify buildability and site risks early.
• Utilise our experience and knowledge of our systems and products to assist your decision making including with materials, testing, performance and sustainability targets.
• Save on variation costs with our early design inputs, technical assistance and detailing.
• Gain price and scope certainty.
• Streamline the consent process with our in-house high risk Producer Statement authors who can provide a higher level of detail to Council.
• Benefit from our early forward planning and material procurement and avoid unnecessary delays.
• Reduce on-site risk through our proactive management of construction risk for critical-path trade.

We specialise in engineered aluminium facade systems and products that are high performing, innovative, sustainable and resilient. Our facade solutions include:

high performance, pressure equalised curtainwall

heavy duty commercial aluminium windows and doors

total vision and structural glass assemblies

specific design total clad systems

solar shading systems

metal folding & finishing

mechanical air louvres

atrium and skylights

integrated fins

channel glazing

rainscreens

shopfront

high end residential windows and doors

Delivering successful high performance façade solutions demands specialist knowledge and expertise, we have in-house professional registered structural and façade engineers specifically assessing each façade design for structural and environmental (seismic and wind) loading and ensure that the façade solution is code compliant.

We have designed several thousand extrusions and many thousands of specific engineered solutions to meet the aesthetic intent of our client’s design and imposed engineering challenges.

Our solutions have included highly complex engineered features as demonstrated in projects such as the University of Auckland School of Science 302, Spark HQ - Christchurch, New Plymouth Airport and FMG Office building - Christchurch; as well as features that have never been undertaken in New Zealand showcased in ASB North Wharf -Auckland and University of Auckland Business School.

Thermosash has manufacturing facilities in Auckland, Wellington and Christchurch operating with sustainable methodologies including responsible purchasing practices, recycling, reuse or responsible disposal.

We manufacture prefabricated unitised curtainwall, commercial windows, commercial doors & sliders, solar shading - fins and louvres, rooflights, mechanical air louvres and rainscreen as well as architectural metal pressings and folding and perforated sheet metal products. 

We constantly reinvest in plant and machinery, and provide ongoing staff training, to enable us to remain innovative and cutting edge in our manufacturing capabilities. We have experienced teams of aluminium fabricators and assemblers, CAD/CAM operators, CNC machinists as well as aluminium sheet metal operators working on a variety of specialist machinery.

The thousands of aluminium extrusions and architectural metal pressings we produce in our facilities are manufactured from super low-carbon aluminium supplied in partnership with a local NZ-owned extruder. We also exclusively use local powdercoaters who have stringent sustainable handling processes.

Thermosash has experienced installation teams focused on delivering exceptional project outcomes, safely and on time, with attention to detail and well considered methodologies.

Our prefabricated facade solutions enable us to close in buildings rapidly saving on programme time and mitigating risk to follow-on critical trades. We have efficient manufacturing and logistics capabilities to ensure just-in-time site delivery, reducing site clutter and the need for large storage areas.

We have a wide range of the latest site equipment to assist with the installation of façades to tight tolerances. We are able to minimise time that a tower crane is required for installation of the façade, and on low rises, due to utilizing our unique lifting and launching equipment we can often do away with the need all together.

Window Engineering Consultants (WEC) offers engineering advice and undertakes physical testing to International Standards and is an IANZ accredited laboratory.

In addition to new product or project testing WEC also offer expertise to review and provide technical reports on existing buildings which may have defective exterior cladding requiring appropriate and effective remedial programs.  Find out more at WEC.
