only possible with an aluco door

Aluco ultra slim steel look external doors are our own design. You will not find this incredibly beautiful floating lock™ appearance anywhere else or on any other interior door. We’ve used our passion and know-how for steel-look glazing, design flair and manufacturing excellence to create two outstanding exterior French doors. Designed with glazing bars, the impossibly thin 20mm dimension is inspired by classic metal doors having a similar dimension. Or, unique on the market is the option of creating an individual steel-inspired door in a fully glazed design. Both feature our specially created and hand-crafted floating lock™ design, where the lock and handle backplate and lock seamlessly join the glass,

The stunning floating™ lock

Using the same slim and steel-inspired frame and sash profiles, our ultra slim steel look exterior doors come in a fully glazed option. The perfect solution when you desire the gorgeous styling only our doors provide but prefer maximum visibility and clarity looking out through your doors. Only Aluco craft internal doors in this new and contemporary look, whilst still giving you the desirable and distinctive lock and handle backplate with one piece of glass.

We can custom-build our exterior doors as single doors or double doors open in or out. Also available are optional side or top panels, corner designs or in virtually any size with additional framing creating impressive entrance screens or exterior patio door units. Whichever design you desire, Aluco ultra slim steel look external doors promise a look and feel like no other product on the market.

The safety glass that comes as standard is specially cut and machined to accommodate the hand-assembled floating lock body using high-specification insulated glass having a soft-coat low-emissivity coating, warm edge spacer bars and argon gas fill.  All doors come with reliable locking via the stylish and reliable handle, operating a multipoint locking system. Also provided is a high-security key cylinder. Despite the thin proportions, your new ultra slim steel look exterior doors provide the dependable security, energy efficiency and reliability you expect.

When you choose to enhance your home with our exclusive ultra slim steel look external doors, you benefit from a hand-crafted door with flawless quality, individual style and a talking point in your home. We will provide a complete choice of outer frame options, a range of stylish door handles and your either the popular black finish or a choice of 150 other colours.

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've been looking for sometime to find a professional company to fit my new windows and doors and I'm so pleased I found you guys! - Aluco's products are 1st class and so easy to arrange, I just called Aluco, spoke to a very helpful lady who put me in touch with my local installer. I would definitely recommend this product & company :o)

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
