Where you can use steel look windows and doors

Aluminium steel look windows and doors are suitable for both new openings and also designed as replacements for existing metal, plastic or timber windows.

Exterior doors and windows are the obvious location, but it’s patio doors of all types, where these doors are particularly effective. For ground or first floor doors, steel-look suits single or double doors, side access doors and even at the front of the house as a porch.

Windows offer the same multiple solutions as other materials, coming with all the required security, energy-efficiency, weather protection and configuration.

For new build openings, these windows come in several frame depth options, opening types, colours and glass specifications.

Of course, aluminium steel look windows and doors provide an alternative solution for the replacement of old metal windows. Many original metal window installations use single glazed, non-insulated products with basic locking. Whilst modern steel windows today do come with the insulation, security and benefits of modern windows, aluminium remains cheaper and in many cases better thermal performance than steel. Steel windows typically offer a C or B window energy rating – aluminium does offer better thermal performance depending on the brand and glass specification.

When replacing older windows, one of the benefits of aluminium is how well they work as new windows in stone surrounds or hardwood subframes. With narrow frames and different edge designs, aluminium steel look windows and doors work well within these often retained building features and, done well, give a similar look to the windows they replace.

When replacing old steel windows, it’s worth considering the style of window being replaced. Crittall® and other metal windows came in different styles and descriptions. Examples include putty line windows, hopper windows, French Casements, W20.

Like other products, old metal windows have names, depending on who made them and when. For example, most steel windows fitted during the 1960’s may often be the W20 type. Other versions include the Universal Range made even earlier or the SMW (Standard Metal Window) also widely used. Aluminium windows are generally intended to replicate these types of steel windows exactly.

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.

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.

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.
