Cortizo 4700 Triple Track Aluminium Sliding Doors
In addition to conventional sliding patio doors which use a single or dual track system our Cortizo 4700 range offers a triple track sliding aluminium door which allows the sliding panels to sit behind each other providing a much wider opening.
Cortizo aluminium sliding patio doors are the perfect alternative to bifold doors as they provide much wider unobstructed glass panels of up to 2.5 metres wide by 3 metres high allowing natural light to flood into the room. As the sliding panels stack neatly behind each other a 3 panel triple track patio door will effectively provide an opening that is almost two thirds of the width of the total door aperture.
Standard configuration for 3 panel sliding doors is 2 panels sliding behind one fixed panel at one end however there is also the option to have all 3 panels sliding so you can choose which side of the door to enter from.
For doors wider than 6 metres there is also the option for 6 panels with the centre 4 panels offering 2 panels sliding right and 2 panels sliding left creating a huge opening in the centre.
Slim 47mm Central Interlocks
The Cortizo 4700 boasts slim 47mm central interlocks as standard reducing the sightline of aluminium profile in your view when the door is closed and maximising the view through the wider glass panels to bring the outside inside as you can see.
Flush track
The bottom track of the door is 47mm high and can be installed 47mm below your finished floor level to provide a fully weathered flush track. If required it can be specified with a 300mm deep projecting cill for the triple track door and 190mm cill for the dual track door increasing the drop required below finished floor to create a flush track to 72mm.
Projecting Cills
All projecting cills are 25mm high.
Depths are 190mm for a double track door and 300mm for triple track patio doors.
High Performance Glass Options
Our aluminium sliding doors can be supplied with energy efficient 1.0 U-value solar control double glazing which helps block UV rays and solar gain whilst retaining your valueable heat in the winter. Alternatively we can provide 1.0 U-value argon filled low e glass for installations where solar protection is not required.
