The Supreme Grey 4m 4 door, full aluminium bi-fold doors are designed right here in the UK and manufactured in our purpose built production facility to the same high quality as all Vufold doors.
This sleek, premium aluminium bi-fold door set has all doors and frames thermally broken for improved insulation and is ideal for those wanting something totally stylish yet resilient. The doors of the 4m Supreme Grey interlock and are 70mm thick with high spec double or triple glazed units making this door set both thermally efficient and environmentally friendly.
For maximum security they have a multi-point locking system which includes twin deadbolts in the upper and lower positions on the main access door that passes the rigours of PAS 24 and the forthcoming EN14351-1 2006 security standard. Also they have extra twin point security bolts which are operated by a handle on the inside.

Supreme bi-fold doors incorporate unique Vufold manufacturing techniques to allow the glazed units to be factory installed including the 'toe and heel' balancing. This enables really fast and easy installation by any competent DIYer or builder in four easy steps.
• Assemble the frame (12 screws)
• Fix the frame into the brickwork opening, square up and level
• Fix the hardware to the doors and the doors to each other
• Finally adjust height and width if needs
And that's it! No specialist aluminium door fitter is required.
Each 4m Supreme door set includes everything you need - doors, frames, hardware, handle, tracks, fixings, magnetic catches, door stop and easy to follow assembly instructions plus the usual easy Vufold adjustability up to 8mm in height and 10mm in width.
Stunning casement windows are also available to perfectly match the bifold doors and complete the look on any extension, renovation or new build home.
