  • Who makes the slimmest sliding doors?

    When it comes to the desirable slimline doors with minimal lines and maximum glass, our Cortizo product is the slimmest available.

    With mullion sightlines of 20mm, there's no better sliding door on the market for minimal looks, maximum glass area and giving you the today's look in modern extensions.

    However, we also know that not every project suits a minimal sliding door. Therefore, we provide even greater choice with our Smart Systems and Reynaers sliding doors. Just as modern but with a more flatline and bold look.

    These sliding doors have sightlines starting at 35mm. So you still get the reduced frame, more glass and better views. Of course with the glass, it's toughened and very energy efficient, helping lower heating bills.

    Here's a rundown of our mullion sizes on our sliding doors.

    Reynaers CP130 sliding doors 69mm or 98mm

    Cortizo 4700 sliding doors, 47mm

    Visoglide Sliding Doors, 35mm or 86mm

  • Can I get a low or flush threshold with sliding doors?

    Yes. For any new opening, we help homeowners and builders achieve the flush or very low threshold.

    The first stage is you and your builder understanding the height of our door tracks and we provide you with this information when you get in touch with us.

    It's then helpful to know the height of your floor inside the room and any outside decking or slabs. This information ensures the doors come at the right sizes and the builder creates the right opening for the doors.

    We work with builders and homeowners ensuring everyone's aware of what's required to get the flush or low threshold. Your builder will also need to provide suitable drainage outside so any water coming down the doors drains away correctly. Acco drains or the the Aquabocci R47 External Barrier system are two types of drainage system that work great with sliding doors and low thresholds.

    And of course, you still get all the water and weather protection.

  • What are the best sliding patio door sizes?

    The great thing about patio doors like these, is they come at the smallest sizes right up to big panels up to 9 metres square.

    The maximum sliding patio door sizes depend on the product.
