Steel replacement doors and windows. Information and advice.

Slimline and industrial in appearance, these modern aluminium windows and doors are very popular today.  Not only are they perfect for replacing old steel windows but they also work very well in contemporary properties. If you desire the period yet modern look in your home, these slimline windows and doors are worth checking out.

Whilst steel replacement is a popular name for these windows, they’re also known as Art-Deco, Industrial, Scandi, Hygge and Crittall® style. Do bear in mind only the original steel window by Crittall is the genuine article and no aluminium window or door in this design matches the styling of steel or this brand name.

These windows are perfect for terraced houses with a new extension or double doors at the back. They work brilliantly in the traditional houses where the living room and dining room on the ground floor are knocked through to create a large living space.  It is popular to block up one doorway with a steel-look or New York-style screen.  We have even had these fitted internally to create a room divider.

To ensure the best effect from new steel-look windows and doors, it is always best to speak to a local specialist in these products and get the best advice.

We install these desirable products every week at Aspire so why not take a look at some of our installations of steel-replacement windows and doors.

We also answer some of the most commonly asked questions about steel look and steel replacement doors and windows for the home.

What is the best colour for steel-look windows and doors?

Original windows and doors were typically painted black.  We find this is the best colour for this style of windows and doors.

One of the benefits of aluminium is that it can be polyester powder coated to virtually any colour you like, but black remains our best seller.  The colour reference used is RAL 9005 matt. Gloss colour black is also available.

How are the bars fitted to steel-look windows or doors?

It is the aluminium bars that give these doors their fine aesthetics so it is important these are fitted accurately and precisely.

At Aspire, we work with the very best aluminium window and door manufacturers that understand how important the bars are not only to the visual appeal but also to the overall quality of the product.

The glass units are accurately calculated with a grid of spacer bars to line through accurately with the rails and to provide symmetry to the doors.  Then the aluminium bars are accurately cut and applied to both sides of the glass units.  A specialist tape is used to bond the bars to the glass that is designed to resist the weather and importantly stay in place for many years.

The aluminium bars are powder coated with the same quality-assured process as the door and frame profiles.  This ensures a consistent colour match throughout and the same level or durability and guarantee.

Can I have opening in steel-look doors?

Yes.  Our steel-replacement door system is available as an opening in or an opening out door.  For most external doors, an opening out door works best as it takes up less space in the home.

For internal doors the choice is yours, whether your doors open in or out.

Can i have integral blinds with steel-look windows and doors?

Integral glass blinds are very popular with bifolding and sliding doors today, offering many features and benefits over conventional after-market blinds and curtains.

As the glass units contain spacer bars that work with the applied aluminium bars it is not usually possible to have integral blinds unless every glass panel has its own separate blind.  However if you have a door with no bars in it, then it is possible to have integral blinds within your steel look door.

Are steel look windows and doors welded?

While it is possible to weld some heavy-duty industrial aluminium products, generally this is not done. For years, aluminium windows and doors have used mechanical cleats and chevrons for windows and doors as well as strong aluminium brackets.

So you will find aluminium steel-look windows and doors are mechanically joined with specialist sealants used to seal the joints and even the small gaps. They are not welded.

Can i have putty-lines in aluminium steel-replacement windows?

The aluminium systems rely on the glazing beads and the profile detailing to replicate the putty lines found in old steel windows.

Contact us and we can go through the range of sections available to achieve the steel-look you are looking for and to try and match your existing metal windows.

How big can i have my steel-look doors?

One of the benefits of aluminium is that it provides wider and taller doors than PVCu. Here are the typical sizes available with our steel look doors. It may be possible to exceed these sizes depending on your individual project.

Single Door Max Width (mm) 1000mm
Single Door Max Height (mm) 2250mm
Double Door Max Width (mm) 2000mm
Double Door Max Height (mm) 2250mm

Minimum door sizes.

Single Door Min Width (mm) 600mm
Single Door Min Height (mm) 1600mm
Double Door Min Width (mm) 1200mm
Double Door Min Height (mm) 1600mm


What thickness of glass do you use in steel look doors and windows?

The glass we use in our doors is usually 28mm Glazing. 24mm, 32mm double glazed or even triple glazed units are available.

Can I have internal steel-look windows and doors?

Yes you can. The latest trend is for internal steel look doors as well as 'New York' Style screens. The internal windows are manufactured without drainage and designed to fit inside your home. Here is a great example of where our steel look windows and screens work on a London property.

Fixed or opening windows, single or double doors as well doors with side or top glazing are all available. We can even provide internal bifolding and sliding doors.

What products are available to replace old steel windows and doors?

Many home improvement firms offering steel replacement windows only do windows and doors.  It is important to differentiate between those companies that simply apply bars to generic doors and windows and those that offer systems designed as a replacement for old steel windows.

Our windows are designed to offer a modern solution to replace your old steel windows.  They are also great for conservation areas (subject to local authority approval) as well as heritage, Art Deco and other buildings.

Nothing beats the authentic steel product, however, due to the very high cost of these, there are aluminium alternatives for windows, doors and screens.

At Aspire Bifolds, we offer:

  • Windows
  • Screens
  • Single and Double doors.
  • Bifolding Doors
  • Sliding Doors


Are steel-look windows and doors A-Rated?

Only with high specification glass units are aluminium windows A-Rated.  Our windows and doors use polyamide thermal breaks that insulate the section and reduces the thermal transmission. Our windows, subject to glass specification meet a C or B rating that meets or exceeds the current Building Regulations.

How much do steel-replacement windows and doors cost?

From the first phone call, a visit to the showroom, through to the site survey and installation, the Aspire team have been unfailingly both very professional, problem solving and friendly. They delivered a great product and service, at a good price, on time, with flexibility, diligence and a smile, and that in our experience is almost unheard of these days.We will definitely turn to Aspire again when we next need windows etc, and can't recommend them enough.

Aspire did the most beautiful job in our house. The installed our windows a few months ago, and I couldn't be happier.They were always happy to answer to our question.They came at 8 o'clock and installed the windows very swiftly with a very clean and tidy result. They decorated afterwards around the windows and you couldn't tell those weren't the original windows as the result was so good.We have a toddler in of the rooms they were installing the windows and they accommodated their work around his naps which was brilliant.If you are looking for anything window or door related look no further, I will definitely recommend and if needed use them again.

We were recomended to Aspire by our carpenter who was building a garden room for us, and we were not dissapointed.From the initial meeting to the completion of the work the company , and especially John Small, and the lads that came to install the doors on one of the wettest days of the year, have been excellent.The Bifolds are amazing. They look so good, and when they open and close they sound solid and beautifully made.Superb job. Thank you.

I don't usually write reviews but Aspire have been an absolute pleasure to deal with from start to finish. After replacing my neighbours sliding doors they came highly recommended. The lady on the phone was extremely helpful and understood my requirements, and my quotation was turned around quickly. I had some technical questions regarding the threshold; and unlike other companies I dealt with, I was not treated as a nuisance and Ji (I hope I spelt this correctly!) talked me through everything. The surveyor arrived within a day of me signing and despite the current situation with many delays, they still installed within the quoted lead time!The Schuco bifolds we now have look amazing and we are so thrilled we went with Aspire Bifolds!Thanks alot Ji and Team.Cliff

I would absolutely recommend Aspire Bifolds. They provided a great product at a reasonable price. Installation team was friendly and professional. They installed in less than a day.We also encountered a small issue with the measurement of the doors, but the leadership at Aspire was quick to cover additional costs incurred to rectify the issue. We really appreciated their professionalism on this matter.

Aspire bifolds removed some old wooden sliding doors and replaced them with some lovely French doors. They did a fantastic job- they spent time with me to ensure I had made the right choice of door, it took no time to fit them and the fitter was friendly, polite, clean and courteous. Quote was competitive and I couldn’t recommend them enough!

We went with Aspire after getting a few quotes, they weren't the cheapest but were still competitive. We chose them on the basis of their reviews and I am really glad we did! The service has been excellent throughout, our doors were installed far quicker than we were expecting, the fitter's attention to detail is great, and the quality of the doors is fantastic.After installation we did have a few problems with finding marks on the glass, which is provided by another firm, and had a few panes replaced. John, the director, ended up coming round himself and offered to replace the final pane. I know that many firms would just have ignored our calls once we had paid everything, so to have this level of service was fantastic. This proved our decision to go with a slightly more expensive firm in Aspire was the right move!

We recently used Aspire for purchase and installation of smart system heritage doors for our extension. We are thrilled with the finished product. John and the team are brilliant, every person I spoke to was helpful and friendly. Email response was really fast. The whole process from start to finish was seamless and stress free.The installers were efficient and tidy, they left the place cleaner than when they arrived. Following installation we noticed a scratch on one of the panes, we thought it could be buffed out, but the whole pane was replaced without issue within a week.It is rare to find a company with such great customer service and work ethic these days. I would certainly be happy recommending Aspire to anyone.

I visited Aspire Bifolds to discuss some technical details of the installation requirement for sliding doors. Both of the staff I dealt with were friendly and helpful and in particular Ji was able to answer all of my questions and demonstrate some of the details on the door installation in the showroom. Overall a very helpful visit.
