Windows

We have 30 years experience fabricating uPVC windows at GJB. We offer a range of Eurocell windows in three different profiles; Chamfered, Sculptured and the stunning new Logik S.

GJB Developments  supplies the trade and house builders are supplied through our sister company GJB New Build. We deliver to most of the UK from our site in Essex.

We supply Residence, Timeless Veka Halo Flush Sash and Aluminium windows too. These are all fabricated within the GJB Group.

Designed in accordance with existing Building Regulations, we manufacture every window from our in-house factory to your exact specification. This results in windows set to impress your customer base.  Coloured windows have increased in popularity and we keep a range of colours in stock for quick turnaround times.  White uPVC remains the most popular for both replacement and new homes, but Anthracite Grey and other colours are increasing in popularity..

Gallery 44 Composite Door frames are sprayed in house at GJB in our spray booth so your customers can colour match their windows with the door frame.

Whether you’re looking for tilt & turn aluminium windows intended for use within a contemporary high-rise complex or something a little more authentic for a domestic rural cottage, our selection has every base covered.
