Window drain / cill detail in tilt and turn units

[MrMagic]

Howdy folks - 

 

Can't seem to find an answer on this one - for a tilt and turn window are there still front drainage holes and do you need cills? or is this a purely uPVC thing? A lot of the aluminium cill profiles seem to butt up to the front face of the window rather than run underneath it - how does that become weather tight?

 

If anyone has a cross section / explanation / photos that would be very very appreciated!!

Anything that opens and closes is likely to need a drain of some sort

Timber alu clad, generally speaking no, the water is allowed to drain behind the cladding and the window cill sits further back (always refer to manufacturer or supplier for clarity on product you're looking at).

Both of the above sections through have drains/weeps in the profiles.

the one posted by Craig i would imagine also has one to drain the centre left void of any collecting water

That’s it

Sorry to jump in after more than a year, but does that mean that you didn’t require a cill?
