Aluminium Sliding Doors for Barnet homes and sites
Sliding doors suit an opening where you want the glass to stay glass — the panels slide past each other rather than fold, so you keep an uninterrupted view even when the door is shut. They're the usual choice where a bifold's stacked leaves would block a walkway.
We supply aluminium sliding doors across the EN postcode area and the rest of Greater London, including North London (6 miles south-south-east), Hampstead (7 miles due south) and Watford (8 miles due west).We manufacture and deliver — your own installer or builder does the fitting.

Aluminium Sliding Doors in Barnet — questions we get asked
Are sliding or bifold doors better for my Barnet extension?
Sliding doors give you more glass and a cleaner sightline when closed, and they don't need clear space for stacked panels. Bifolds open the whole aperture. If you want the opening fully clear in summer, choose bifold; if you want the view year-round, choose sliding.
What threshold options are there?
There's a standard 47mm threshold or an eco-drain low threshold. The threshold needs detailing alongside your drainage, so decide it with your builder early and ask us for the threshold detail.
What's the lead time for aluminium sliding doors in Barnet?
2–10 working days from confirmed sizes — the same wherever you are. Barnet is about 159 miles south-south-east of our Leeds factory, and every order is delivered on our own fleet, to a fixed date confirmed when you order.
Do you offer trade prices on aluminium sliding doors in Barnet?
