Frameless Bifold FAQs

Technical Specifications

Please contact us via email (info@openenclosure.com.au) to obtain a copy of our framing specifications and further information relating to preparation works such allowing for a recess or provisions for drainage. If you require a physical sample of our framing, please contact us and we can mail this out to you.

Product Demonstration

In Victoria, our showroom is located at 19/442​ Geelong Road, Yarraville VIC 3013. In NSW, our showroom is located in Canterbury. You can call us on 1300 812 282 to arrange an appointment. Private viewings can also be arranged in some of our commercial applications.

Weather Conditions

Can it handle strong winds? Our system is tested for air and water infiltration. This allows for installation in some of the most demanding and harsh Australian conditions. Invisible weather seals when in place eliminate the drafts that are inherent to most frameless systems. We specify a glazing thickness and maximum height we can achieve based on the wind classification of your property. This is determined by a number of factors including the terrain category, shielding, topography and region. For more details on this, feel free to contact us to discuss how to obtain your wind classification and whether or not our system is appropriate for your project.

Is it waterproof? Yes. Small weather seals are specified to make it a water tight solution. These are approximately 3mm in width and are adhered to the profile of the glass panels. The system has a unique operation that provides a compression across the system when it is locked. The compression of the seal prevent any water ingress. The seals are not clip on/clip off seals and can be replaced at any time in the future. These seals are covered under our warranty.

Is it fire safe? Our system can be used in fire rated areas where an exemption is obtained. The exemption is often granted due to the nature of the materials used in the Open Enclosure system. This includes use of a toughened glass with a minimum thickness of 10mm and the use of aluminium as a framing material. Upon request, we can send you further information on the framing and details that can be shared to apply for this exemption.

Glass Options

Can the glass be double glazed? Due to the system being frameless, we cannot double glaze the glass. Double glazing typically requires two panels of glass with a vacuum or gas filled space in between, meaning that a frame is needed to hold the gas filled space.

How do the thermal properties compare to double glazing? Our standard glass is a 10mm toughened. Due to the thickness of this glass, the thermal properties are impressive but may not perform as well as a double glazed system. We also have low-e glass as an option. The “e” in low-e stands for emissivity. The low emissivity coating (low-e) means that less heat passes through the glass than would usually be the case (compared to standard float glass) which is great for retaining heat inside the house.

Can you tint the glass? Yes, we can tint the glass during the manufacturing process. This is something we discuss with you when quoting for an opening.

Can you vary the thickness of the glass panels? Either a 10mm or 12mm toughened glass can be specified. The choice of glazing thickness will depend on the wind classification of the site and the height that you are looking to achieve. Clients may opt for a thicker glass to also improve the sound performance.

Can you change the panel width? Our panel widths vary from 350mm​ – 830mm. When we are working with a client on designing their system, we will discuss our recommendation but it often comes down to client preferences based on their desired aesthetic outcome.

Frame Details

Frame colour options? Framing is powdercoated any colour from the Dulux Duralloy range. We can also quote for specialty colours if required.

Can the tracks be recessed? The bottom track can be recessed to sit flush with your floor. Details of this setup can be emailed to you to assist in preparation. This will require a further understand of your application to ensure appropriate provisions are made for any draiange.

What material is the frame made from? The frame is made from aluminium.

Security

The system is fitted with a mechanical lock that will secure all panels in place when engaged. This means there is no access enabled from the external side. There are optional locking upgrades available whereby we can allow for internal / external access with keyed entry.
