What supply-only means for your job

Supply-only is exactly that. We are the fabricator behind your sliding door order, not a competitor for the install. You stay the contractor on site, you manage the fit, and your client never deals with us. We take your drawings or surveyed sizes, work out the right sliding system for the opening and the budget, fabricate the units in Haydock and hand them over glazed and ready to hang.

That suits installers, builders, joiners, main contractors and commercial fit-out teams who want a dependable aluminium sliding door supplier behind them without buying a whole factory. If you already run a trade account with us you can quote sliders alongside your bifolds, casements and entrance doors on one order.

Large panels, slim interlocks and big glass

Sliding doors earn their place where the client wants the most glass and the least frame. The strength of aluminium lets us run large, heavy panels on tight sightlines, so the interlock where two panes meet stays slim and the view stays open. We size each panel to the opening rather than forcing a standard pane, which keeps the glass-to-frame ratio high.

We build single-track, double-track and multi-track layouts, with panels parked or stacked to suit the reveal. For very wide openings we can split the run across more panes to keep individual leaf weights and roller loads sensible. Maximum achievable panel sizes depend on the chosen system and the glass make-up, so send the opening and we will confirm what stacks up. The maximum sizes guide covers the limits we design to.

Thresholds, thermal performance and weather

Threshold choice is where a lot of sliding door jobs are won or lost, so we spec it deliberately. We supply standard upstand thresholds for weather-exposed elevations and low or flush options where the client wants a level transition to a patio or terrace. Tell us the floor build-up and whether level access matters and we will detail the threshold to match.

On thermal performance, the units are thermally broken aluminium and we quote whole-unit Uw from 1.0 where specified, with the glazing spec and frame system chosen to hit the target. We can accommodate glazing from 22mm up to 58mm depending on the system, which gives room for high-performance double or triple units, and acoustic glass to Rw 46 dB where the site needs it. Final figures are confirmed per finished unit at quote. Our aluminium U-values guide explains how whole-unit figures are reached.

Bifold or sliding, and where each one fits

Trade buyers ask us this on most patio jobs. Sliding doors give the cleanest single sheet of glass and the slimmest closed-state sightlines, and they take large panels well, but a portion of the opening is always glazed because the panels slide rather than fold away. Bifolds open almost the full aperture by stacking the leaves to one side, at the cost of more frame visible when closed.

For a wide opening where the priority is the view and a flush threshold, sliders usually win. Where the client wants to throw the whole wall open in summer, a bifold is often the better route. We are happy to quote both so you can put the choice to your client. The bifold vs sliding doors comparison sets the trade-offs out in full.

Security, standards and accreditation

Aluminium sliding doors are often the most accessible opening on a property, so the locking and the security route matter. We supply PAS 24 security product routes where the job calls for it, and the doors are fabricated to BS EN 14351-1 for windows and doors. We provide UKCA marking and Declaration of Performance support so your paperwork stands up for building control and for the client.

VitrineAlu is a member of the Council for Aluminium in Building. We do not name system houses on quotes. You tell us the performance, security and sightline targets and we specify the right system to hit them, then quote it cleanly.

How to order and what we need from you

Send structural opening sizes or surveyed sizes, the number of panels and the stacking direction you want, the threshold type, the finish and any thermal, acoustic or security targets. If you only have a rough drawing, send that and we will come back with the questions that matter. We specify the route, fabricate and supply the finished units for you to install.

Homeowners reading this should use our find an installer route, as we supply the trade rather than sell direct.

Common questions

Do you install the sliding doors or only supply them?

Supply only. We fabricate and supply the finished aluminium sliding doors and you install them. You stay the contractor on site and your client deals with you, not us. Homeowners are pointed to our find an installer route.

What Uw can you achieve on aluminium sliding doors?

Whole-unit Uw from 1.0 W/m2K where specified, with the frame system and glazing chosen to hit the target. We accommodate glazing from 22mm to 58mm depending on the system. Final figures are confirmed per finished unit at quote. See the U-values guide.

How large can the panels be?

Aluminium takes large, heavy panels on slim interlocks, so wide expanses of glass are achievable. Maximum panel sizes depend on the chosen system and glass make-up, so send the opening and we will confirm. The maximum sizes guide covers the limits.

Should my client go for sliding doors or bifolds?

Sliders give the slimmest sightlines and the cleanest single sheet of glass and suit a flush threshold. Bifolds open almost the full aperture. We quote both. The bifold vs sliding comparison sets out the trade-offs.

How do I get a price and open a trade account?

Send drawings or sizes through the quote page and we will specify and price the right route. Pricing and lead time are confirmed per project. To trade with us regularly, open a trade account.
