How to fit blinds on sliding doors

The rise of ultra-slim sliding doors has created a new interior design challenge: how to incorporate window dressings on large moving panels? While homeowners invest heavily in floor-to-ceiling glass to maximise views, many are left facing issues with solar glare, "fishbowl" privacy concerns, and summer overheating.

Glazing experts at IDSystems share how to navigate the technical complexities of fitting blinds on contemporary sliding systems.

• Because sliding doors overlap and move horizontally, traditional blinds are often unsuitable as they can obstruct the sliding mechanism or interlock.
• Accurate and detailed measurements are critical, as mistakes can result in clogged up sightlines or awkward finishes.

“For example, roman blinds can look great,” says Edward Stobart. “Just ensure you mount them high enough so the ‘stack’ doesn’t cover the top of the glass or sag so you hit your head when walking through.”

Stobart has rounded up his tips for fitting blinds on sliding doors, from mounting options to measurement:

The most common fitting on sliding doors. By mounting on the ceiling above the frame, the doors can slide freely without hitting the blinds.

Sliding screens can also be recessed into the side reveal of the doors. Set internally to the tracks of the doors, the retractable sun shades and insect screens offer a stylish solution for inside-outside living. As these screens are incorporated into the door system itself, they are not generally suited for retrofitting to existing doors.

[edit] External blinds

An increasingly popular option, external blinds sit on the outside of the glass and prevent direct sunshine from reaching the door system. By preventing sunlight from reaching the glass, these blinds can significantly reduce overheating.

Lastly, while it’s not an option for sliding doors, there is another option for slide and turn and bifold door systems. This approach sees Venetian or pleated blinds installed between the glass of a double or triple-glazed unit, creating a maintenance-free way to create privacy or reduce glare.

[edit] How to measure your sliding doors to fit blinds

Accurate measuring is essential to achieve a clean finish and proper functionality.

• Outside recess measurement: Measure the full width of the opening (horizontally), allowing for overlap on each side to ensure full coverage and minimise light gaps.
• Panel alignment: For wider sliding doors, multiple roller blinds are often the most practical solution. Measure each section individually, aligning with the panels for greater flexibility and easy access.
• Drop measurement: Measure the height of the opening (vertically), from the intended fixing point to the desired finish, usually just below the door frame or to the floor level.
• Measure obstructions: ensure to measure any obstructions, such as door handles or frames, to ensure the blind can hang freely without interference.
• Stacking depth: Measure the space that fully opened blinds will take up, which will vary depending on the style and size of the blinds.

“The most common mistake people make when measuring for blinds is forgetting the ‘stacking depth’. If you choose vertical blinds that drop down from the ceiling, remember that when the door is fully open, those blinds have to bunch up somewhere,” Stobart explains. “Ensure your track extends past the door opening so the blinds don’t block your view, or the breeze when the doors are open.”

Stobart gives an extra piece of advice: “If fitting within a recess, it’s important to measure in multiple places and use the smallest dimensions, while also confirming there is enough depth for the blind mechanism.”

[edit] Choosing the right type of blinds for your sliding doors

• Roller blinds: Usually, they are installed above the door and roll up neatly to vanish out of sight, leaving your view completely unobstructed when open. The most efficient way of designing the blinds is to opt for one blind per panel – this gives you flexibility when opening the doors.
• Venetian blinds: Vertical Venetian blinds remain a hugely popular option for many people simply because they are incredibly practical. Individual slats hang vertically from a track and can be tilted to filter light or drawn back completely.
• Roman blinds: If roller or Venetian blinds look too ‘office-like’ or clinical, Roman blinds offer a softer, more furnished alternative. They bring the feel of curtains to your sliding patio doors without the floor-to-ceiling bulk.
• Sliding screens: Large, wide panels of fabric roll out from a cassette from the side along a track. Whether you opt for a blackout style sun screen or choose an insect screen (or both) the panels slide in a similar way to the door itself.

[edit] Finding the right window dressing for your glazing

Choosing the right blinds for your sliding doors is likely the finishing touch to your renovation project. Whether you choose the clean lines of a panel blind or the practicality of Venetian blinds, make sure your choice complements your home’s style and the quality of your glazing.
