Specifying slim sliding doors: what to consider

Idsystems’ Edward Stobart gives the inside track on how to ensure you get a high-quality door with performance to match its looks

Since 2012, when Idsystems first launched THEEDGE, our Build It Award-winning ultra-slim sliding door system, the number of projects incorporating narrow framed door systems as part of their design has skyrocketed.

There are now lots of slender framed products on the market from a wide variety of suppliers. So how can you differentiate between them? Having set the trend eight years ago, we’re in a good position to advise on the factors you need to consider!

Sightlines matter, but so does frame depth

When it comes to judging a truly slim sliding door, the depth of the frame matters just as much as the width. Whilst most sightlines have now reached an almost invisible 20mm, the frame depths vary dramatically.

To provide structural stability, a number of systems on the market need chunky reinforcing additions to the outer frame. This means that, unless the doors are viewed from completely face-on, they can appear anything but slim. The design of’ THEEDGE2.0 combines narrow 20mm sightlines with incredibly slender 51mm frame depths ensuring the doors appear slim, whatever angle they’re viewed from.

Good security should come as standard

Every door system that is fitted on a new build home should meet the requirements of PAS 24:2016 testing, in order to meet the requirements of Building Regulations Document Q.

However, the same standards don’t apply to renovations and other projects – so not every door is equal in terms of its security specifications. Indeed, some products will require upgraded locking mechanisms in order to comply. In some cases, this might be add as a surcharge on top of the original quotation.

Are flush floor finishes best?

Achieving a completely flush finish between inside and out is a key design element for many people installing sliding doors into their home. Creating a seamless transition between inside and out is an appealing idea, but it is important to check that it’s the right option for your project, and that you aren’t reducing the protection the doors offer from wind and rain.

Look for versatile door configurations

Whether you are planning a threepanel set of sliding doors leading out to the garden, contemplating an open corner, or looking at a setup that slides into a pocket in the wall, it is crucial that you find a system that provides you with total flexibility in design. That way, you’ll get the door that’s best for your build.

For instance, THEEDGE2.0 is available in panel sizes from 800mm to 3,000mm wide, and up to 3,000mm high. You can also choose to have all the panels sliding and, depending on configuration, the option to achieve up to three-quarter openings. The system works well on its own, or it can be incorporated alongside fixed frame windows and even glass-to-glass corners to a complete glazing solution.
