Stacking Glass Walls

Vetrostax Stacking Glass Walls

Weather resistant, frameless stacking glass doors and windows up to 4m in height

Welcome to flexible, frameless, weather resistant glass wall design. As a top supported system, Vetrostax can be configured for stacking doors up to 4m in height, or as stacking windows to maximise passive airflow and eliminate mullions. Stacking configurations are almost limitless, offering flexibility to accommodate any space.

PROJECT SHOWCASE
Integrating stacking glass windows with balustrades: Homegroup, Perth
Cooling Brothers worked closely with HomegroupWA to deliver the full glazing package into the leading home builders' stunning new head office in Perth. A key component of the glazing was the design of the stacking glass windows wrapping the exterior of an expansive alfresco space. These windows achieve year round use of the indoor/outdoor area, maximising light, passive airflow and connection back into the showroom space within the office. This case study explores how Vetrostax stacking walls can be used a window configuration for alfresco spaces, including integration of the system into glass balustrades.

FAQs

All our most commonly asked questions. Can't see your answer? Please call us on 1300 040 799 or get in touch via contact form below.

What is the difference between PVB and SGP?

While both PVB and SGP offer excellent optical clarity, SGP (SentryGlas Plus Interlayer) is 5x stronger and up to 100x stiffer than PVB. SGP was created by DuPont and is produced for the global glass market by Kuraray.

SGP retains structural integrity upon failure, making it suitable for frameless applications like Vista View Frameless Balustrades. In comparison, PVB is a cost-effective solution for applications where higher structural performance is not required. Standard PVB interlayers will not retain structural integrity upon breakage.

Do you provide an engineering service for custom laminates?

Yes, we can offer engineering certification for custom laminate projects if required. Please contact us for further details.

Can you install my custom laminated glass?

For specialised glazing projects, we have an experienced structural glazing team who can provide a complete measure and installation service. Please contact us for details.

How is custom laminated glass produced?

Stacking glass walls utilize laminated glass, which is produced by joining two or more glass panels with an interlayer, commonly PVB or SGP. The glass is permanently bonded by applying heat and high pressure within a vacuum chamber known as an auto-clave.

What decorative options are there for custom laminates?

Stacking glass walls can incorporate various decorative options. Vanceva offers a range of colour options for interlayers, DigiGlass provides digitally printed interlayers for unique laminating solutions, and ImagInk ceramic printing can also be utilized for direct glass printing and subsequent lamination.

Are custom laminates Grade-A safety glass?

Yes, laminated annealed glass and laminated toughened glass used in stacking glass walls are classified as Grade-A safety glass according to AS 1288-2006 (Australian Standards) 2023.
