⚠️ The Reality of Apex Windows
Apex windows are not standard.
They are:
Angled
Asymmetrical
Often oversized
Structurally demanding
Yet most people treat them like normal windows.
👉 That’s where everything goes wrong.
❌ Problem #1: Using Standard Curtain Tracks
This is the biggest mistake.
Standard tracks are:
Not designed for angles
Not strong enough
Not engineered for apex movement
Result:
Curtains stick
Fabric pulls unevenly
Tracks bend over time
👉 If your track isn’t custom - you’ve already lost.
❌ Problem #2: Poor Measurements
Apex windows require multiple measurements, not just width and drop.
You need:
Left drop
Right drop
Apex height
Angle accuracy
What happens if you don’t:
Curtains hang uneven
Gaps appear
The whole window looks off
👉 There is ZERO room for guesswork here.
❌ Problem #3: Ignoring Curtain Weight
Apex curtains are HEAVY.
Why?
More fabric
Greater drop
Often lined or blackout
Cheap systems = failure:
Sagging tracks
Broken gliders
Curtains dragging
👉 This is where “budget options” cost more in the long run.
❌ Problem #4: No Plan for Curtain Movement
Here’s something most people don’t think about:
👉 Curtains move differently on angles.
They naturally:
Slide downward
Gather unevenly
Put pressure on one side
Without proper design:
Curtains won’t open smoothly
They bunch awkwardly
They look messy
❌ Problem #5: No Stacking Space
Where do your curtains go when open?
Most people don’t plan this.
Result:
Curtains block the window
You lose natural light
The room feels smaller
👉 This is a design mistake - not just a fitting issue.
❌ Problem #6: DIY Installations
Let’s be direct.
👉 Apex curtain installs are NOT a DIY job.
Why?
Angles must be precise
Tracks must be supported correctly
Weight distribution matters
DIY outcome:
❌ Crooked tracks
❌ Poor movement
❌ Expensive rework
🔥 What a Correct Apex Installation Looks Like
Now let’s flip it.
When done properly, apex curtains:
✔ Open smoothly
✔ Hang perfectly symmetrical
✔ Enhance the architecture
✔ Feel premium and effortless
✅ The Right Way to Do It
Step 1: Accurate Survey
Every angle measured precisely.
Step 2: Custom Track System
Bent aluminium or engineered solution.
Step 3: Correct Fabric Choice
Weight matched to height and width.
Step 4: Professional Installation
Proper bracket spacing and alignment.
Step 5: Movement Testing
Ensuring smooth operation before completion.

You can have the best fabric in the world…
…but if the track is wrong?
