Understanding sliding door thresholds

Sliding door thresholds are complex engineered aluminium profiles designed for smooth sliding doors, weather protection and overall door security. Just like bifolding door thresholds, it’s perfectly possible to get that desirable low track, near-flush floors and a minimal step out to your patio area or garden.

In this article, we help you understand the process for achieving the perfect sliding door threshold level giving you the best functionality out of your new doors.

Information about sliding door thresholds

Sliding door thresholds are available as single, double or triple tracks. The number of tracks depends on how many door panels your door opening needs. Sliding door tracks also give you the funtionality with two or three panel doors to slide them to the left or the right.

The sliding and fixed panels do not overhang the outside faces of the threshold on the inside of the room so panel clearance is not required. Therefore, whether you need new sliding doors to replace your old doors or need to plan new doors for your extension, we can help you achieve the ideal floor finish.

At the same time, sliding door thresholds need to keep your home protected from the weather and wind and provide effective drainage of water away from your doors. Water drainage is crucial as rainwater falls down your door glass, onto the track and away from your doors.

Any of our premium sliding door brands, have the thresholds and tracks designed to ensure the smooth operation of your sliding doors with effective weather protection.

Early planning and communication get you the best sliding door threshold.

For your new doors, getting the perfect result and doors you are happy with means communication in advance of you getting your new doors. For a new opening, get your door installer involved early in the process with your builder or architect. Many builders aren’t always aware of the complexities of sliding door tracks, and some even assume all sliding doors are the same. Crucially, getting the new opening built right ensures you get the step height you desire. It also avoids expense, delays and frustration modifying the opening if it’s set wrong in the first place.

Communication between your installer, architect or builder is even more important when you consider the dept of triple or quadruple track sliding doors. These substantial aluminium profiles go way deeper than a typical door frame. The structure your builder prepares must accommodate this substantial frame depth often at 180mm or more.

Also important is all parties involved in your property project the desired floor finish level, whether you’re having tiles, carpet, wood flooring or laminate. Your floor level needs factoring into what your builder prepares and the doors we create for you.

How sliding door thresholds drain water to the outside

All sliding door thresholds are designed with drainage. The many grooves you see on a sliding door track will understandably collect water as they’re not flat or sealed. However, engineering and clever design means any water drains out through carefully machined slots.

For new openings, there needs to be a facility for suitable drainage at ground level. Popular methods include the creation of suitable channels and drains or an ACO drainage product. Engineered to take rainfall or water away, these types of drains even look neat and discreet, hidden from sight or part of the architectural feature of your doors.

Other considerations to get an attractive low threshold on your patio doors

For existing doors, the process is slightly more complex and it also depends on your particular property. We can discuss the various options with you to help you achieve a low step and easier access to the outside.

The flatter threshold will usually come with new doors in new openings as these are designed to work together from the outset. For existing doors the level may not be as low but still provide a better solution than your dated doors.

From the first phone call, a visit to the showroom, through to the site survey and installation, the Aspire team have been unfailingly both very professional, problem solving and friendly. They delivered a great product and service, at a good price, on time, with flexibility, diligence and a smile, and that in our experience is almost unheard of these days.We will definitely turn to Aspire again when we next need windows etc, and can't recommend them enough.

Aspire did the most beautiful job in our house. The installed our windows a few months ago, and I couldn't be happier.They were always happy to answer to our question.They came at 8 o'clock and installed the windows very swiftly with a very clean and tidy result. They decorated afterwards around the windows and you couldn't tell those weren't the original windows as the result was so good.We have a toddler in of the rooms they were installing the windows and they accommodated their work around his naps which was brilliant.If you are looking for anything window or door related look no further, I will definitely recommend and if needed use them again.

We were recomended to Aspire by our carpenter who was building a garden room for us, and we were not dissapointed.From the initial meeting to the completion of the work the company , and especially John Small, and the lads that came to install the doors on one of the wettest days of the year, have been excellent.The Bifolds are amazing. They look so good, and when they open and close they sound solid and beautifully made.Superb job. Thank you.

I don't usually write reviews but Aspire have been an absolute pleasure to deal with from start to finish. After replacing my neighbours sliding doors they came highly recommended. The lady on the phone was extremely helpful and understood my requirements, and my quotation was turned around quickly. I had some technical questions regarding the threshold; and unlike other companies I dealt with, I was not treated as a nuisance and Ji (I hope I spelt this correctly!) talked me through everything. The surveyor arrived within a day of me signing and despite the current situation with many delays, they still installed within the quoted lead time!The Schuco bifolds we now have look amazing and we are so thrilled we went with Aspire Bifolds!Thanks alot Ji and Team.Cliff

I would absolutely recommend Aspire Bifolds. They provided a great product at a reasonable price. Installation team was friendly and professional. They installed in less than a day.We also encountered a small issue with the measurement of the doors, but the leadership at Aspire was quick to cover additional costs incurred to rectify the issue. We really appreciated their professionalism on this matter.

Aspire bifolds removed some old wooden sliding doors and replaced them with some lovely French doors. They did a fantastic job- they spent time with me to ensure I had made the right choice of door, it took no time to fit them and the fitter was friendly, polite, clean and courteous. Quote was competitive and I couldn’t recommend them enough!

We went with Aspire after getting a few quotes, they weren't the cheapest but were still competitive. We chose them on the basis of their reviews and I am really glad we did! The service has been excellent throughout, our doors were installed far quicker than we were expecting, the fitter's attention to detail is great, and the quality of the doors is fantastic.After installation we did have a few problems with finding marks on the glass, which is provided by another firm, and had a few panes replaced. John, the director, ended up coming round himself and offered to replace the final pane. I know that many firms would just have ignored our calls once we had paid everything, so to have this level of service was fantastic. This proved our decision to go with a slightly more expensive firm in Aspire was the right move!

We recently used Aspire for purchase and installation of smart system heritage doors for our extension. We are thrilled with the finished product. John and the team are brilliant, every person I spoke to was helpful and friendly. Email response was really fast. The whole process from start to finish was seamless and stress free.The installers were efficient and tidy, they left the place cleaner than when they arrived. Following installation we noticed a scratch on one of the panes, we thought it could be buffed out, but the whole pane was replaced without issue within a week.It is rare to find a company with such great customer service and work ethic these days. I would certainly be happy recommending Aspire to anyone.

I visited Aspire Bifolds to discuss some technical details of the installation requirement for sliding doors. Both of the staff I dealt with were friendly and helpful and in particular Ji was able to answer all of my questions and demonstrate some of the details on the door installation in the showroom. Overall a very helpful visit.
