French windows

October 13, 2012

French windows don’t have a stile in the middle, it opens up completely, in this case because the customer wants to be able to step out through the window and sit in the garden.  As if this isn’t difficult enough they also had to be inside opening windows, two things that doesn’t make it easy to make a water and draft proof design.

Double rabbets on the sides and the window stile, with draft-seals.  Single rabbet on top and bottom with a ‘click’ on the windows. I always try to avoid wood on wood when window is closed, water likes to sit in between there it’s called capillary force, I used draft sealing on all these points.

Flush bolts on the inside to hold the one window.

Flush-bolt bottom,the windows are sticking out over the rabbet on the outside the sill is sloping and attached on the window is a water-drip.

Water-drip under the sill, lead curves up under and just behind the water-drip, water-drips at bottom of the windows, ventilated glass-beads with water-drip.

Outside rabbet end is cut under an angle so it doesn’t trap water.

I did all I could think of; to stop water and draft getting in or getting trapped, oh yes and water-drip at the top of the frame. This wall is most exposed it’s situated quite high and looking out over the Irish-sea.
