Stellar Aluminium Systems windows and doors.

Designed from the ground up, Stellar is a high performance quality aluminium system. New aesthetics, better ways to make it and significantly improved fitting are just a few of its new design features. Stellar also comes with genuine sales opportunities for window companies, while offering homeowners a more exclusive aluminium proposition for their homes.

Aluminium Windows and Doors by Stellar.

The collection of Stellar aluminium doors and windows provide a one-brand solution and cover most project and property requirements.

Aluminium Windows.

For aluminium windows, there is a choice of a flush casement, a fully flush casement, fixed light windows, bay windows and combination window/door screens.

The standard flush casement has the inset sash on the outside with a conventional stepped detail on the inside. The fully flush casement replicates the exterior feature on the inside of the window.

Stellar aluminium doors.

For side doors or back doors, there is a choice of single or double doors. These use an attractive symmetrical sight line without the ‘picture frame’ detail found in other types of residential doors.

All door products come with multi-point locking, security cylinders and durable door handles and a choice of accessories. The doors integrate with the window system for creating door/window screens.

Finally, there is a low threshold option for use inside the home, such as closing off a conservatory.

Sliding patio doors.

Capitalising on the patio door market, Stellar offers a lift and slide door with sliding panels up to three metres wide.

The door comes with a range of interlock options as well as a choice of regular, low or wheelchair-friendly thresholds.

Also available is a lift and slide operation, four-point locking, weather tested to current standards and a C-Energy Rating.

Bifolding Doors.

The Stellar bifolding door comes designed for residential property with options for opening in or out doors up to seven sashes.

Door panels of up to 1000mm wide and 2400mm wide meet the requirements of most replacement door projects. Of course, they work well in new extensions too. The doors come with slim sightlines, certified security and a range of RAL colours.

For installers, Stellar bifolding doors come with the option of PVCu glazing beads. Not only does this offer more flexibility to the product, but also substantially speeds up and simplifies the glazing of bifolding doors.

Stellar windows benefits for installers and the trade.

Manufacturers of Stellar report to us that by far, the most positive comments about this new aluminium are how attractive it looks. Futuristic yet also classic looking, with clean elegant lines, neat joints and a flush casement detail. These windows sit well not only as traditional window replacements but also contemporary windows in new building projects.

For installers looking for improved sales opportunities, Stellar not only offers a window that doesn’t look like other brands, but also promises a product that’s easier to work with, having time-saving features. From the packers to the glazing beads, the designers looked to offer a faster and better-fitting window with fewer procedures on site.

Fabricators particularly benefit as the system comes designed for better fabrication. At window transom/mullion joints especially, Epwin has designed Stellar for faster fabrication, fewer parts and reduced waste.

Stellar windows and doors continue to help installers with more common parts, greater integration and even compatibility with existing PVCu accessories and cills. The characteristics designed into this innovative system makes Stellar products ideal for all manner of installations, renovations and building projects.

Fewer materials, rapid manufacturing, less visible aluminium and great new design deliver flexible and functional windows and doors.

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.
