If you’re thinking about replacing your dated patio doors or starting to plan a new extension, sliding patio doors are a great solution. Large glass panels, smooth sliding, slim sightlines and lots of light are just some of their advantages. They also come with the desirable sliding door flush threshold.

What do you do when replacing old doors in getting a minimal step? For new extensions how does the sliding door flush threshold keep water away? In this article, we tell you everything you need to know.

How to get a sliding door flush threshold

For new extensions, creating a flush threshold on sliding doors is popular. Your new doors look better at floor level. A low threshold also creates a more fluid link between your room and your patio area. However, you also need the right design, weather protection and the correct deflection of rainwater away from the doors.

It’s important you work with your chosen door supplier as early as possible. If you are employing an architect as well as a builder, involving them early ensures everyone understands what’s involved. Importantly, you get the result you want without errors and delays. You’ll also get the perfect doors you’ll be happy with.

While it’s true you can set most doors down lower, aluminium generally produces a better result. Aluminium doors are always slimmer than timber or PVCu versions and this includes the threshold. Our range of doors come with a standard threshold. However, with a correctly built opening, it’s possible to get that desirable minimal step and flush floor.

Or course, a sliding door flush threshold not only looks great but also provides better access. Young children, the elderly, prams, kids bikes or wheelchairs. Just some of the improved uses with a lower threshold.

All our sliding doors come tested to the latest weather performance standards. When designing a sliding door flush threshold we work with your architect and builder. Together we ensure the opening is correctly built and the correct drainage method the doors need.

The sliding door track is the critical detail

One great piece of advice is to ask us to provide a door track and threshold sample to your builder. Depending on how many panels you have, these vary in depth and size. If your builder sees the physical item, they can then ensure your new opening is built to accommodate your new doors. Another benefit is the drainage at the bottom of the doors is done exactly right.

Whether you choose our minimalist Cortizo or Origin sliding doors with the structurally bonded design and minimal frame, or a conventional sliding door, both come engineered for the best drainage with weather protection.

Tips and Advice for a sliding door flush threshold

  • Plan early before your builder constructs the opening.
  • Get your architect and builder to see the doors or a sample of the track.
  • The threshold you get also depends on whether your doors have two, three, four or even six panels.
  • We always recommend you see doors in a showroom. This is the best way to understand how they work.
  • Ensure all parties are aware of your internal flooring or carpet and external decking or slabs.
  • Talk to us.
