Getting the Crittall® look with Aluco steel-look interior doors

There are several differences between aluminium and steel doors and windows. Of course, only the genuine steel product provides exactly the right styling, sightlines and feel. Aluco doors provide an aluminium alternative whilst still taking inspiration from the genuine product. Just like steel, aluminium provides long service life, low maintenance and substantial colour choices.

At the same time, Aluco steel-look internal doors come with the signature design details of classic steel doors. These include:

  • The iconic steel look using slimline glazing bars for the grid-like appearance
  • Unique floating lock design or standard thicker plate behind locks and handles
  • Seamless flow between rooms and flush floors with no threshold
  • Distinctive traditional or contemporary door handles and accessories
  • The signature black finish or a choice of any other colour

Key design features of Aluco doors

The significant design differences between Aluco doors and other steel-look brands come about because this is a fit-for-purpose internal door product. Other brands use exterior grade doors. Whilst these also work well, they come with features not needed internally.

As a result, Aluco aluminium doors come with several design features and benefits, Crittall look interior doors similarity as well as providing the required door functionality.

Improved Crittall look interior doors

Exterior-grade steel-look doors come with a thermal break. Thermal breaks aren’t required inside the home. Aluco doors use solid and multi-chambered profiles. The benefit is a slimmer product front to back. Moreover, opening the doors reveals a clean and neat finish on the inside of the frame profile. There’s no visible thermal break of exterior doors.

Crucially, the overall aesthetics are neater, sleeker and more elegant.  A 52mm slim outer frame, 37mm or 20mm glazing bars, full sealing and structural couplers designed to look neat inside the room.

The benefit of single glass with an Aluco door or screen

Again as a purpose-designed interior system, Aluco doors come with a single glazed option. It’s incredibly hard to find single glazed aluminium products since around 2000. Following the change in Building Regulations and improvements to U-Values and Window Energy Ratings, pretty much all single glazed options for aluminium are discontinued. 

Interior doors generally don’t require double glazing. With this in mind, single glazing provides additional aesthetic benefits over a double glazed door.

  • A significantly better looking product all round
  • You don’t see the glass spacer bars of exterior quality doors
  • The glazing method is neater than exterior doors
  • The glass to metal junction throughout the door is significantly more attractive using a square glazing bead. 

Giving the required style typical of classic period metal doors are substantial glass options including reeded glass, sandblasted, obscure or clear.

Better locks and hardware for interior doors

As you do your research around steel-look interior doors, the small details matter. Most interior doors between your rooms don’t need a lock. And most other interior aluminium-steel-look doors give you one. 

As exterior-grade doors, the system comes designed for a multi-point lock facility with additional key locking. With an Aluco interior door system, you get the familiar latch lock of internal doors enhanced by an extensive range of contemporary or period furniture. There’s a bathroom latch and deadbolt option keeping the door tight and secure and of course, the privacy expected with a bathroom door. Other lock options include a latch only or latch and cylinder.

All of the hardware, again inspired by Crittall look interior doors, creates an authentic product in style and functionality. The handle options include a one-piece handle with back plate, a circular backplate with separate escutcheon and finger bolts security the secondary leaf of double doors.

Product Guarantees and Testing

Aluco products come with a specific installation guarantee provided by the Approved Aluco Dealer. The products also come with a ten-year guarantee on locks, hardware, aluminium profiles and the powder coated finish.

The internal finish of handles is also guaranteed and suitable fire testing certification on the lock bodies, subject to application and installation.

I contacted Nick @ ATS for guidance on what aluminium sliding door systems would be suitable for an opening in an extension that is going to be both wide and tall. He came back really quickly with very detailed and incredibly helpful advice. He is clearly extremely knowledgeable about the systems on the market and their respective features and capabilities. If you’re feeling a bit lost by the overwhelming range of choices out there, I’d definitely recommend contacting him.

After a lot of research to find doors that would meet our unusual size requirements and feeling increasingly uncertain about the best way to spend our small budget, I stumbled on the ATS website, and I'm so glad I did! I contacted ATS to request advice and Nick promptly replied with a wealth of information, providing us with options and relevant contact details. I only wish I'd found them sooner!

I've been so confused about how to achieve the look I'm after, and going round in circles with various window/door companies, trying to get away from the huge chunks of plastic currently around my windows. I didn't expect an email to a company found through a Google search to really help - but I was desperate, so I tried. I'm SO glad I did. Finally I have clear explanations from ATS of where I've been going wrong, exactly what I'm looking for, and a list of local companies that might be able to provide it! The response has excelled my expectations and I feel as if I'm finally inching closer to a home with which I'll be happy and comfortable: thank you.

It is rare that I write reviews, however after my very positive communication with Nick - enquiring about suitable slim sash aluminium windows for my project, I felt that a review was definitely warranted. I can reinforce the many positive reviews posted so far, Nick was very quick to respond, providing comprehensive detail, with excellent independent advice.In summary, great service, thank you Nick.

I dropped Nick at Aluminium Trade Supply an email re high security slim sightline bi-folds and their alternatives and he responded that quickly (and so comprehensively) that I felt bad I’d not paid him for his time!Nick Sir your product knowledge is outstanding and you are providing a level of service that goes wayyyy above and beyond expectations. I’ll definitely make sure I mention Aluminium Trade Supply to anyone I encounter looking for a fenestration solution 🙏🏼

We are looking to replace some old UPVC patios doors with aluminium ones. The ATS website is a great source of advice in an area where clear information is sorely lacking. Having used the website, I then followed this up with a number of specific questions relating to our search, and Nick came back very quickly with clear, detailed and very useful advice.I have been very impressed with both the website and with Nick's advice. My only regret is that I didn't come across ATS before replacing various windows in 2021 - I'm sure it would have saved me a lot of grief and money! Thanks again Nick.

My experience with this firm was exceptionally good and this is notalways the case as a female, dipping a toe into technical waters.I was spoken too with courtesy and at a level that helped me consolidate what was needed .On top of that I was given a list of companies and places where I could obtain the type of product I needed.I could not thank them enough and would certainly go there again and reccommend others do too.
