The Smart-Zero Line folding Window System from Smartech Door Systems is designed for window openings that are on the boundary-line. This new innovative design enables the product to open and rise up and out of the way. It is an elegant system ideal for cafes, restaurants and entertainment establishments, great for maximising airflow between adjoining spaces and creating a sense of space when it isn’t always available. The Zero-Line Folding Window is functional, inviting and stylish. The Zero-line is all you need to create inviting spaces, protected from the elements.

Window Openings

The opening where you have chosen to install your Zero Line Folding Window should be prepared to the exact finished opening sizes listed in the window specifications sheet, to provide perfect sealing and smooth operation, and to guarantee correct tolerances.

Window Construction

The Zero Line Folding Window is constructed of two folding frames attached with stainless steel hinges to four axles. These are connected to steel bearings that are guided within a specially extruded aluminium running guide.

Note: Smartech’s products are to be installed to the structure designed to suit our fixing requirements.

Quality Control

Quality control procedures are carried out by a series of thorough inspections at every stage of the project - from the purchase of raw materials, the cutting of materials and manufacturing, through to delivery. Strict quality control procedures have enabled Smartech Door Systems to position itself as the preferred supplier to our large clientbase, from Landscape Architects and Pool Designers, to Architects who all recommend our product Australia –wide and across the globe. Quality inspections are always conducted prior to delivery to our clients. We have enlisted a team dedicated to meeting and exceeding our client’s expectations, always emphasising the principles of a value-added service, constantly improving manufacturing techniques, producing superiorquality products and providing a professional service at all times.

Window Frame & fittings

The Smart Zero Line Folding Window frame consists of an extruded aluminium profile with tig-welded members to reinforce our already robust frames. Running guides and fittings are always made from the highest quality materials with most components powder-coated as standard. Aluminium fabricated frames are balanced according to the weight of the window and our double-seal system has been designed to make sure there is no air leakage and the seal fits perfectly with the frame.


All glass supplied and fitted by Smartech Door Systems is 6.38mm laminate safety glass as standard. Where alternative glass is required please consult the manufacturer.

Note: The use of other glass or glazing material should be referred to the manufacturer due to additional weight that may or may not be required to keep the window system operating easily.

Weight Covers

Weight covers are designed to enclose weights out of view and to ensure safety. Covers wrap around the weight mechanism extending from the track and returning to the wall.


All manually operated windows are fitted with side bolt locks at the midpoint of the window system frame. 


The Zero Line Folding window system is balanced according to the weight of the frame allowing the window to open and close effortlessly. Window movement is guided by bearings attached to the frame, operating within the specially extruded aluminium guides.

Key Benefits

The Zero Line Folding Window opens up and rests parallel with the ceiling avoiding stacked panels to the side of the opening. The result is a userfriendly and aesthetically pleasing look, with the style and quality our customers have come to expect. Our construction and design ensures the window system is hard-wearing and will out-live our competitors and as no track is required on the bench or window sill, even air flow and a safer more user friendly addition to your commercial space is created. The system is designed for commercial projects and is manually operated.
