Information about Stellar Bifolding Doors

Part of the Stellar collection of windows and doors, these bifolds offer strong double-walled aluminium profiles, durable and colour-rich finishes. Homeowners and the trade can buy from Epwin’s strong dealer network of reputable manufacturers and installers.

Stellar bifolding doors while fit for purpose as a stand-alone bifold, appeal greatly to installers and homeowners in properties with existing PVCu windows. Available with a square or bevelled sash profile and bevelled. Also available are sculptured PVC-U beads. You can use these doors as a new patio door to houses while not obviously contrasting with other nearby doors or windows. The profile designs also make them suitable to match all manner of existing PVCu systems, not just those available from Epwin.  The overall benefit is a slim and attractive bifold, complementing older or recently fitted windows and doors elsewhere in customer property.

With quality components, substantial colour choices and a matching suite of other windows and doors, the product provide a one-brand solution for end-users. Manufacturers and installers benefit from the  Epwin Group reputation for quality and reliability.

Key features of Stellar doors

We’ve reviewed the Stellar bifold giving you more information. Everything about Stellar bifolding doors delivers performance and reliability. Parallel stainless steel tracks provide a smooth slide and fold action. The four-wheel bifolding door rollers come with brushes to help keep the track clean. Double hinge fixings ensure opening sashes are always reliable.

The flexibility with existing PVCu components also provides several features and benefits over full aluminium bifolds.  The doors come with PVCu beads offer substantially faster glazing than aluminium. At the same time, they’re easier to work with the product on site.  The PVCu integration also extends to the range of cills and ancillary profiles you get with the product making installations easier for installers with less material stockholding required. For those still wanting an aluminium bead, one is available.

Stellar bifolds also offer the many benefits of PVCu beads. Pvcu beads substantially speed up glazing compared to aluminium beads. For those that want the aluminium beads, there’s the benefit of the patented quick-fit aluminium bead that we’ve seen and it too is much faster than conventional beads with the leg.

  • Two to seven door panels, opening in or out
  • Competitive sightlines compared to other bifolds, with a 145mm glass to glass sightline
  • Quality multi-point locking systems and a security certified product
  • Available 28mm double up to 44mm triple glazed

Every detail of the product offers manufacturers a simple to fabricate door and installers one that is easy to fit.  Security hinges, co-extruded gaskets to the glazing beads and flexible design options.

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.
