Frameless glass sliding door systems: minimally visible design explained
With their clean lines and wide-span glazing, sliding doors are popular for their frameless or minimally visible look. ‘Frameless’ aluminium door and window systems have the narrowest frame profiles to deliver panoramic views over your garden or outdoor space.

The best slim aluminium sliding doors for a frameless look
Sliding door manufacturers like ourselves aim for products with maximum visible glass and minimum visible frame. For example, ODC’s SL320 sliding system boasts a 20mm frame profile. Our advice to customers is that if you love the idea of minimal sightlines, it’s important to look at the profile of the frames, not just from face on, but from an angle, too.
Some sliding system frames are ultra-slim in one dimension, and compensate for this on the other for strength. This creates chunkier side-on views and correspondingly wide tracks at floor level. Design considerations like wind load resistance and security do impact on sliding door frame width and sightlines. We offer sliding doors with slightly wider sightlines to meet customer needs for enhanced security and the most robust weather performance.

Sliding doors with pocket or recessed installation
The frames of sliding doors can even be recessed into the adjacent walls, floor and ceiling so that very little can be seen around the outer edges. Pocket sliding doors give the illusion of a frameless glas door. Depending on the width of the opening and the number of doors/panels specified, the vertical lines of each panel will be visible.
Solar-control sliding doors for open plan country home
A minimally visible sliding system such as ODC SL800 is purposely designed to provide the greatest impact by being scarcely noticeable from the front view. No wonder we call it the invisible door! It has such a slim profile that, rather than taking centre stage, it plays a supporting role. The huge glass panels ensure that your eye is drawn beyond the product itself.
Solar control coatings are helpful in many south-facing installations. The calculations to optimise solar gain and reduce over-heating in buildings with large expanses of glass is a primary concern of your architectural glazing designers and is often an area of collaborative planning with your architect.

Glass sliding door handles explained
Our largest frameless sliding doors can be operated with one hand
High quality handles for sliding doors are made of aluminium and finished with the same weather-resistant, low-maintenance powder coating as the frames. Sleek, ergodynamic and integrated into the frame, they maintain the seamless, minimalist aesthetic of the doors themselves. Robust, quality screws and fixings will also ensure problem-free longevity.
In-line or lift and slide operating systems for frameless sliding doors?
In-line sliding doors glide open and closed on steel rollers inserted into tracks. Lift and slide designs lift the doors onto rollers before sliding. Both systems offer that effortless glide operation, but the lift and slide is more popular with homeowners looking for enhanced security and ease of use.
Customer reviews of ODC slimline doors
Rated 5 out of 5 stars
Excellent all-round experience
My experience with ODC was very positive. Firstly, the advice given from the sales manager (Matt) on the various options available was excellent – we were swayed from a large bi-fold arrangement to a much more suitable slider arrangement. Secondly, the fairly significant issue we had (our fault!) on the day of installation was skillfully and professionally solved by the installation team. The look and quality of the product is superb – stunning in fact. This is a company that is passionate about what they produce!17 April 2024

Beautiful slim heritage crittall look doors
ODC were a pleasure to deal with. Really friendly staff and I’m so pleased with the super thin profiling that they managed to achieve for our sliding doors. They managed to produce a lovely heritage look with bespoke glazing bar design. I had thought I needed Crittall to achieve this but the aluminium was great as a less expensive alternative.01 July 2025
How to find the best frameless sliding doors?
When choosing a UK manufacturer and supplier for frameless or minimally visible frames for your glazing project, do take a look at the product in use. Nothing beats a visit to a showroom with working product displays. Compare it with others for ease of opening and smoothness of operation. They will certainly vary, and if you intend to open the door often a heavy or ‘sticky’ door is a nuisance. Ask about a maintenance routine and optional coatings to keep your glazing functional and beautiful.
Similarly, check out reviews and testimonials on your supplier’s aftercare and service. Often, this is as important as the product you choose for ultimate satisfaction. Our videos page has a number examples of our doors being used.
