High Specification UPVC Bifold Door

slim sight linesThe Imagine bifolding door was designed from the ground-up using dedicated upvc profiles that produce a door with slim sightlines yet are strong enough to offer sashes up to a metre wide and capable of being glazed with 44mm triple glazing if required.

The concealed running gear allows the smooth operation of opening and closing the door with the minimum of effort and all the hardware is a bespoke design for the VEKA Imagine door and is manufactured by ERA one of the UK's leading lock and hardware suppliers.

Door handles are specially designed to ensure that the panels will stack neatly together and magnets on the panels ensure that there is no opportunity for the panels to 'creep-close' once opened.

Door styles of up to 7 panels wide are available and matching single and french doors can also be provided using the same profiles and thresholds so all doors will match.
