The ultimate guide to the Aluco floating lock

The Aluco floating lock is unique because it gives you the same distinctive feature backplate that defines the steel look style, and unlike other steel-look doors on the market, the option of a fully glazed door or a design with slimmer glazing bars matching better the styling and sightlines of steel doors. Our own creation and reinforcing our commitment to giving you the best possible steel-inspired doors on the market, the floating lock creates ultra-slim steel-look exterior and interior doors. In this guide to help you choose the right Aluco patio doors for your project, we explain the benefits and design features of the Aluco floating lock and why this style of door can enhance your property project. The Aluco floating design is unique to our doors, and you won’t find it anywhere else on a comparable product.

Why the aluco floating lock is special

The Aluco Floating Lock is our way of making the steel look different from other products on the market and giving you more design options than any other product. It starts with one of the most distinctive features of steel-look doors – the lock and handle feature backplate. The feature backplate is arguably what makes this style of glazing so desirable and appealing.

Instantly recognisable alongside thin frame profiles, period hardware, reeded glass and black finish, the feature backplate behind the handles is an iconic feature of classic, industrial and Art Deco doors. The design of the feature backplate came about because the slim steel frames that inspire our products were far too thin to accommodate a lock.

Why is the feature backplate required on steel-look doors?

Other steel-look doors must have bars above connected to the feature backplate, and both our Exterior and Interior collections also offer this feature and helps replicate the original steel look with great effect.

The constraint with the conventional design is that you must have the bars above and below the feature backplate. The other reason bars are placed above and below the backplate is they cover exposed aluminium profiles, screw ports, fixings, and edges. So they’re not only decorative.

With most other steel-look doors, the placement of these bars is essential. The downside is fewer design choices.

Why the aluco floating lock is better than other steel look doors

The Aluco floating lock provides greater design freedom than other types of steel-look doors. We’ve mastered the art of creating a beautiful feature backplate, but without the limitations of other types of doors. Our floating lock design gives you several advantages other doors in a similar style cannot provide.

  • The slimmest glazing bar options starting at 20mm
  • The option of a fully glazed door with the feature backplate
  • The illusion of the feature backplate floating into the glass
  • Available with patio exterior single or French doors
  • Available with interior single or French doors
  • Virtually unlimited door and screening designs

Whether you choose a fully glazed option or one with glazing bars, only Aluco offers an ultra-slim steel-look exterior or interior door with thin profiles, more design options, classic and contemporary styling.

The fully glazed door adds an altogether different aesthetic unique to Aluco, giving you maximum transparency and clarity as you look through your doors. The perfect balance of steel-look and ultra-modern.

The glass challenge creating an Aluco floating lock door

The glass is one of the challenges in creating a door design like no other. Whether you choose a double-glazed exterior door or a single-glazed interior version, the glass is another special creation. Our glass is specially machined to accommodate our floating lock design, with no lines, seams or glass joints.

At the same time, the sealed units had to conform to industry-wide requirements for double-glazed doors. That is the essential safety glass, warm edge spacer bars, argon gas fill and low-emissivity coating. The result is glass that follows the form of the lock backplate perfectly.

Where you can use Aluco Doors with the floating design

This incredible design allows you to transform your home with exterior and interior doors, with the same beautiful styling, functionality and quality. In the Aluco Exterior Collection, you get thermally insulated, double-glazed doors working exactly as you expect. Functional, reliable, secure and energy-efficient doors created in a style you won’t find anywhere else.

Our exterior doors also come as standard with multipoint locking, quality key cylinder, full door sealing and the option of a standard or lower-set threshold. Doors can open in or out and can combine with side or top panels where you have a larger aperture.

Aluco doors for the inside of your home also come with the floating lock design, single-glazed with safety glass, open in or out, and no visible threshold letting your floors run smoothly and uninterrupted between your rooms, optional side panels and a choice of our gorgeous door handles and accessories.

Even better with the Aluco Floating Lock is the option to have the bars if you want them. You may prefer all glass doors for the inside of your home and doors with glazing bars for your patio doors. Here is an example.

Just completed house renovation, using all the internal bespoke doors with glass panels. Absolutely delighted with the quality of doors and service. I was assisted every step of the way in getting the right size and format of extremely tall door. Keiran has been exceptionally helpful to deal with over the months from ordering to completion. 10/10I never usually do reviews but but I would say the whole experience and end result that has been achieved has been amazing.

So pleased with our new Aluco bifold doors, the best we could find on the market! We wanted bifolds with maximum glass area and no bulky frame and the Aluco doors were the perfect choice. Stunning, deep matte black colour, high quality, great choice of hardware and a first-class service. Highly recommend!

I recently had 3 sets of ALUCO exterior crital styled steel framed doors fitted to my property as part of an ongoing renovation. After looking around at various options Aluco was the only manufacturer that I felt could deliver the style I was looking for. With most other companies I thought the design was bulky and not finished to the finesse Aluco has achieved . Based on my experience I can honestly thoroughly recommend this manufacturer and will look to use them again on any future projects
