Ultra Trade Frames provide supply only Liniar uPVC bi-fold doors across East Anglia and the South East to trade customer. These intelligently engineered double glazed bi-fold doors use cutting edge design to minimise heat loss and maximise the opening area.
They are ideal for any project where customers require a stylish feature to expand their living space into the outdoors.
Our Liniar bi-fold doors are highly secure, which can be enhanced by the high performance Modlock™ range which offers even greater strength and rigidity, combining the structural benefits of an aluminium door with the energy efficiency of uPVC.
These thermally efficient doors come with extremely low U values. The standard door achieves a U value of 1.3 W/m2K, and the Liniar ModLok™ bi-folding range can be fitted with triple glazing, reaching a U-value of 1.0 W/m2K.
We offer a range of thresholds for our uPVC bi-fold doors, including ultra low thresholds that enable easy access for wheelchair users.
