Frameless glass sliding doors are aluminium patio doors designed with a minimal amount of framing.  These modern and highly-engineered sliding doors are ideal for home improvement projects where the thinnest possible doors are required or for floor-to-ceiling doors and windows.

Information about frameless glass sliding doors.

It is important to understand the construction of frameless glass sliding doors as there is some confusion, especially online as to what constitutes a frameless product.  Many sliding doors are marketed as frameless however they possess both an aluminium outer frame and aluminium around the sliding panels.

All frameless sliding doors require some aluminium framing, therefore, no sliding door is entirely frameless.  Aluminium framing still plays a vital part in these frameless sliding doors for many good reasons.

  • To enable door handles to have a secure fixing point.
  • To enable colour choice.
  • To provide protection to the glass unit edges.
  • To assist in the overall structural integrity of the product.

These slim-framed aluminium sliding doors can be frameless thanks to the various methods with which they can be installed.  One of these is recessing the frame into the wall to conceal it, leaving just he door panel visible.  The result is a near frameless appearance.

The most common use of these thin aluminium sliding doors is external to create floor-to-ceiling glazing, as doors in a new extension, or sliding doors to replace the outgoing old door.  For enhancing a living space or creating an impressive glass room, these slim sliding panels are ideal.

As well as external use, they can be used as a room divider, within a conservatory or new glazed extension. Simply put, they are suitable for use internally or externally like any other type of door.

Where can you buy aluminium frameless sliding doors?

It is very important to choose a door installer that has expertise in these types of sliding doors as well as bifolding doors and complex installations.  Any good sliding door company should be able to demonstrate their experience through a good portfolio of installations, customer testimonials, certification and accreditation.

The installation of these doors differs from a conventional aluminium patio door bifolding door.  A frameless glass door is manufactured around the glass and glazed doors are difficult to handle without expertise and/or special handling equipment.  Regular patio doors are designed to arrive on site unglazed with the glass being one of the last things to be fitted with the product.

These frameless glass door will either be supplied and fitted by the company that manufactures them, or they will be purchased from an experienced trade supplier.  The trade supplier route does not necessarily imply a more complicated supply chain.  Some customers will like their installer to also be the manufacturer, however, the vast majority of the door industry does not manufacture and buys-in all its products.

Our research shows a large number of British and European sliding door systems available on the market.  One of the most dominant in the UK is Cortizo Systems of Spain.   Many of the top brands in the UK are original or re-engineered Cortizo system doors marketed under different brand names.  This is nothing to be concerned about as many companies choosing one strong brand indicates just how good Cortizo systems are and the trust these specialist door installers place on their aluminium systems company.  All doors based on the Cortizo system are made in the UK.

IQ Glass is another excellent company providing slim framed sliding glass doors.   Doors from IQ Glass are premium sliding doors with a very thin 21mm mullion. Some version of the doors available from IQ Glass is available in moving panels of up to 12m2.

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.

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.

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.
