Ultimate Evolution Adjustable Jamb Aluminium Bi-folding Door

The Ultimate Evolution [EVO.] aluminium bi-folding door brings cutting-edge innovation to Sliders UK’s Ultimate Range of market leading PAS24 and Part Q approved, bi-folding, inline sliding and composite doors.

With ultra slim sightlines – even compared to the standards set by other leading aluminium systems – it’s a bi- folding door that comes with end-user appeal and high margin ‘engineered-in’.

With significant installation efficiencies delivered through an innovative fully adjustable jamb option, it’s even more popular with fitters.

Installation in 45-minutes

Simplified door squaring and setting

Its’ highly innovative fully adjustable jamb means that the Ultimate Evolution is a highly ‘forgiving’ bi-fold to fit.

The easy-adjustment system delivers up to 8mm of tolerance, making if far simpler to align the door – even where apertures are out of square.

This dramatically simplifies door squaring and setting which means the Ultimate Evolution can be installed in as little as 45-minutes.
