Sliding Door Glossary of Terms

A modern sliding door offers your home fantastic views through the large glass panels. These highly engineered products are now better, slimmer and more desirable than ever before. If you are currently in the market for a new sliding door for your home, you may come across technical terms or descriptions you are not familiar with. We have compiled a sliding door glossary, explaining what some of these terms mean.

Sliding door System.

sliding door glossary of terms article

The sliding door system is the name of the sliding door from the aluminium systems company that designed it. Our new Origin Inline Sliding door is developed by Origin that is a systems company. The same applies to our Schuco sliding door.

Sliding Door configuration.

The configuration of the sliding door is its design. The number of door panels, their sliding direction, colours, handle options and sliding door tracks all fall under the sliding door configuration.

Sliding door interlock.

Sliding doors are designed to meet together in the closed position with the one side of a door panel engaging with the opposite side of the adjacent leaf. This is the sliding door interlock; the vertical mullion you see when the doors are closed.

One of the best features of modern sliding doors is the interlocks are slimmer than ever. If you are looking for a sliding door with a near frameless appearance, our Origin sliding door has an interlock of just 20mm, making it one of the thinnest sliding doors you can buy. Our Schuco sliding doors give you the option of a 108mm interlock or a slimmer 48mm interlock.

Inline sliding doors.

Inline sliding doors work like traditional patio doors where the sliding panels are encased in the frame and the track. Inline sliding doors are typically available as two, three, four or six panel doors

Lift and Slide doors.

Lift and slide doors are the latest generation of sliding doors where the door panels sit behind the frame rather than within it. The advantage of lift and slide doors is that they can be partially opened for ventilation and they offer more opening options.

Lift and slide doors are operated by the handle. A turn of the handle on the closed door lifts the sliding panel away from the frame, ready to push in the desired direction. This is different from inline sliding doors where the handle is only used to pull or push the doors.

Polyester powder coating.

Polyester powder coating is the method of colouring and protecting aluminium sliding doors. The colour of your new sliding door starts as a powder that is applied to the aluminium profile while putting an electrical charge through it. The powder bonds to the profile and is then baked to cure and create a durable finish.

Our sliding doors are available in over 200 different colours, and you can even have a different colour inside and out.

Sliding door track.

The track is found at the bottom of the sliding door. Sliding doors are available with one, two or three tracks depending upon how many sliding panels are needed and in which direction they slide.

Every sliding door has sophisticated rollers at the bottom of each panel ensuring even the heaviest doors are light and smooth to open. The track can be fitted directly on the structural floor or recessed to create a lower, more levels threshold.

Sliding door jambs.

Similar to the sliding door track, jambs are found on the sides of the sliding door. The number of door panels can dictate the number of door jambs required. The sliding door jambs also provide the locking points for the handle that operates the shoot bolts and other types of locking systems.

Sliding door cill.

The sliding door cill is the same as a window or door cill. It is an aluminium section that is found beneath the sliding door track. A cill is designed to deflect water and rainfall away from the doors and to the outside.

Sliding door cills come in various depths to suit the number of tracks and the individual property. You may not even need a cill in some cases. We can advise your further on the cill requirement at the time of the survey.

Thermal break.

The thermal break is a polyamide strip that creates a bridge between the inside and outside faces of the aluminium on your new sliding doors. Thermal breaks ensure the aluminium is insulated and makes your sliding doors warmer and more energy efficient in conjunction with the glass. The thermal break is visible only when the doors are open and can be black or painted the same colour as the doors.

At Open Living our showroom showcases both standard and slimline sliding doors. Visit us or contact and come see how a latest generation sliding door can work in your home. We offer both inline and lift and slide doors as well as matching roof lanterns, windows, bifolding doors and front doors.

Open Living was one of the last suppliers we discovered, but we were taken by their great range of windows, doors and lanterns as well as their sales team. Diane walked us through the many options but also listened to our preferences. Rather than steering us toward the most expensive option they were usually able to offer a choice on each aspect and the pricing was very transparent and competitive. Excellent quality ranges of windows, doors and lanterns. We opted for the Origin bi-fold doors, Origin aluminium windows and Atlas roof lights, all superb build quality/spec and great colour options.The installation team led by Danny and backed up in the office by the all-knowing Marsha and Linda were efficient, thorough and a pleasure to have on-site, coordinating well with our builder. Our neighbours also used Open Living before us and had a few issues at installation, but we believe these were mainly due to a supplier issue. All our windows, doors and roof lights went in as planned, well secured and sealed, with no damage.The only little point of feedback on their whole process is that the final quote and specification can spread across more than one document which did add a little uncertainty. This meant we had to double-check exactly what was coming. An all-inclusive final statement of all the options would be good. However, with a little bit of checking everything did come exactly as expected and we are extremely happy with the finished project.We would definitely recommend Open Living.

We purchased 1 set of bifold and 1 set of French patio doors, both Origin. Sales approach and customer service was excellent. Fitting and installation also excellent. Can't fault the product, either. Would have been 5 stars if it wasn't for an issue we had around the height of the threshold, which turned out to be much higher than we wanted/were expecting. This issue was resolved in a satisfactory way after discussion. Would definitely recommend, but my advice is to make sure the threshold height for patio doors is agreed at the survey and written on the paperwork before parting with any money.

Lovely people to do business with, we bought some BiFold doors and a window from OpenLiving. We did have a couple of minor teething issues once fitted but these were dealt with quickly and without fuss. Recommended!

I looked into a number of companies before deciding on Open Living in Letchworth for our bifold doors. I wanted the bifolds to be from a manufacturer that was very regarded, and Origin (though Open Living can also supply from Schuco and some other suppliers) certainly fall in that camp. I also liked the fact that Open Living were close to home, which made repeated visits to their showroom easy to make. Throughout the process, Linda and Marsha were professional and courteous and I would thoroughly recommend anyone who is looking to get bifolds to put OpenLiving Ltd on their shortlist.

So far I have ordered 12.5m sliding doors, 1 set of aluminium bi-folds and 5 windows from Open Living. The fitters are all great guys, and they take time to do a good job.The service and the products supplied have been excellent. I will be ordering more windows and do not hesitate to recommend them.

Had some OW80 windows that were fitted some time ago (by other installers, who had lost the cill caps).Marsha kindly helped me get some replacement items from Origin despite there being no financial incentive for open living to do so.Assistance has been very much appreciated and would highly recommend.

Had a great experience with Open Living. We had a 6m run of Origin bi-fold doors, an Atlas sky light some upvc windows installed. Customer Service and communication was good throughout, the installation guys did a good job and their technical guy was helpful with determining levels so we could achieve a level and flush threshold on the door. On top of this they were by far the lowest priced installer we found for the Origin doors which we had quoted by another three suppliers. Would recommend to others and will use again.

We weren't quite sure what bi-folding doors would be best but all the options were clearly and concisely laid out before us and some great solutions suggested to the issues we hadn't been able to work out on our own or with our builder. The showroom has lots of choice, brilliantly set out. We decided that Open Living would install our doors and they came and did a wonderful job.Looking forward to the spring to really get our new "open living" lifestyle underway!!
