Apex curtains fitted to a large triangular apex window
Best for
Apex & vaulted spaces

Ideal for sloped tops, tall glazing, dramatic gable shapes and triangular architectural windows.

Typical direction
Custom track + lined drapery

Most apex curtain schemes work best with a custom track and a heading style chosen around the room.

What matters most
Proportion, softness, control

The right curtain scheme should soften the glazing, frame the architecture and feel balanced in the room.

Why apex windows need a specialist solution

Apex windows are one of the hardest glazing shapes to dress properly. The slope, the height and the visual drama of the glass all change how curtains should be designed.

A standard curtain approach often feels wrong on these windows. The proportions can feel off, the track can look awkward and the room can lose the elegance it should have.

What a good apex curtain scheme should do

  • • Respect the slope and overall shape of the glazing
  • • Bring softness and warmth into a dramatic room
  • • Improve privacy, blackout or thermal comfort where needed
  • • Feel architectural rather than improvised
  • • Turn a difficult window into a genuine feature

Our approach to apex curtains

We start by understanding the shape, the room and what you want the curtains to achieve. From there, we guide the heading style, lining level, track direction and overall look.

Some apex rooms suit calm, tailored wave pleat curtains. Others need more softness, more fullness or a more luxurious visual presence. The point is to design around the room, not force a one-size-fits-all answer.

Apex window answers

Straight answers to the questions people ask about apex curtains

Apex windows combine shape, height and installation constraints, so the best answer usually comes from treating the curtain, track and fixing method as one system.

What curtains work best on apex windows?

Made-to-measure curtains on a track planned around the slope are usually the strongest option. The heading, fullness and lining should be chosen around the window geometry, room use and how much privacy, blackout or thermal comfort is needed.

Can curtains follow a sloping ceiling?

Yes. A specialist track can be planned to follow an angled or sloping line where the structure and fixing points allow it. The track route, curtain heading and stacking position need to be designed together so the finished curtain hangs cleanly.

Can apex curtains be blackout?

Yes. Blackout lining can be specified for apex curtains, although the overall result also depends on the window shape, track position and any light gaps around the edges. Bedrooms often need these details considered from the start rather than treating lining as an afterthought.

Curtains or blinds for apex windows?

Curtains are often the more flexible solution for large, angled and dramatic apex glazing because they can follow the architecture while adding softness, privacy and insulation. Blinds may suit some shapes, but the practical limits increase as the window becomes taller or more complex.

How are apex windows measured for curtains?

The useful measurements go beyond width and height. The slope, side heights, peak position, proposed track line, fixing surface, floor level and stacking space all matter. For complex or high windows, a site measure is usually the safest basis for the final design.

How are very high apex curtains installed?

High installations are planned around safe access, suitable fixing points and the weight of the track and curtains. The access method depends on the building and height, so installation planning should happen alongside the curtain and track design rather than after manufacture.

Heading, lining, fabric and finishing details all work together

The window shape is only one part of the design. The finished result also depends on how the curtain is headed, what it is made from, how it is lined and which finishing details are used.
