Painted pelmet with sheer & blockout curtains - Kellyville

It seems the latest trend in window design is to incorporate hidden cavities in the ceilings to conceal curtain tracks blinds. This ensures a seamless and tailored look in your home where you don’t see tracking or mechanisms.

Great in theory…however most builders, architects and home owners get the dimensions horribly wrong!!!

When you are first putting pen to paper with your home design it is prudent to have a fair idea of what window coverings you will be needing. You don’t have to select fabrics or colours, but you definitely need to consider whether you are having blinds, curtains or a combination of both.

WHY? Well it’s actually quite obvious…different window treatments take up different amounts of space and more often than not, the poor window covering supplier (that’s us!) has to deal with the less than adequate space provided. Most homes have a cavity between 100 and 140mmm.

Double S-fold heading

So here’s a general guide for you:

  • 100mm will house single blinds or a single curtain track for most pleats and perhaps an sfold at 80% fullness
  • 110-120mm is needed for a full sfold or a single motorised track
  • 180-200mm is required for double blinds and double curtains (again not full sfolds) OR a blind and a single curtain
  • 210-220mm is required for double sfolds and motorised double tracks

If you have 90 degree corners (and it seems many new homes do), make sure the cavity edge is angled across at 45 degrees rather than a right angle if using curtains. Curtain tracks are bent in curves, not angles, so sometimes they need a bit of extra space at corners.

This is not rocket science!!! By having this basic knowledge BEFORE the builder starts his work, you  will save yourself a lot of grief when it comes to the window coverings DO NOT be guided by the builder or the architect. ALWAYS seek the advice of a professional window covering supplier in this instance.
