In addition to the conventional single or dual track sliding patio doors, we also offer a triple track aluminium sliding patio which allows the sliding panels to stack neatly behind each other – providing a much wider opening. A 3-panel triple track patio door will effectively provide an opening that is almost two-thirds of the width of the total aperture. A triple track system also provides an additional option of allowing all panels to slide if required.
Visoglide triple track aluminium patio doors are the perfect alternative to bifold doors as they provide much wider unobstructed glass panels of up to 2.5 metres allowing natural light to flood into the room.
High Performance Double Glazing
Our aluminium patio doors can be supplied with energy efficient 1.1 U-value Staycool solar control double glazing which helps block UV rays and solar gain whilst retaining your valuable heat in the winter. Alternatively we can provide 1.2 U-value argon filled low e glass for installations where solar protection is not required.
A selection of handles are available to make the most of your new sliding patio doors. Popular choices include luxury ‘D’ handles or a simple twist lever handle that doesn’t intrude into the visible glass area.
If trickle vents are required a frame extender will be required for fitting on top of the outer frame head. For a dual track door the height of the extender is 20mm and for a triple track patio the height is 42mm.
