CatiaMan, not a problem for the drawing… I took the liberty to make some generalizations, every window is a bit different, in thickness and size and kind of glass, depending on the style, quality and R value that you trying to reach…. Just so you know.
I drew a standard (what is built in in most houses these days) outside window with frame. The lower part (thepart which must fight off the water and precipitation) has on the one I drew up for you, an aluminium profile to keep water out, but can be built with out, if you make sure that the upper ledge of the lower frame has a slight grade (about 10°) to keep water out, and running down. all corners on the outside MUST be rounded slightly with about a 3 mm radius. This insures that what ever you are using for surfacing (paint, lack/varnish, lasuer, whatever) maintains a constant thickness to protect the wood, (on a sharp corner or too small of a radius, cant manage the corner, and thins in this spot making it vulnrable (spelling?) and of outside you do not want that). Also keep in mind that UV rays are damaging over time as well so that over time too.
Here is the lower part
here is the upper part:
You will notice I did not put many measurements in (except for the general frame sizes), thats because it really all depends on the kind of hardware you are using.
The rubber gasket/weather seal is also a generalization, because even here there are a thousand different kinds depending on what you are doing and quality, the one i used in the drawing is very common.
But overall I can say definetly this is a good general example of how windows are done here, this of course is a simpler version, there are more variants, all depending on how thick your walls are and how much noise you want to keep out and warmth in.
Before I forget, on the drawing, what you were asking about, is Geriffelteleiste, and I mean by that the wood strip that is holding the windowpane in, is not solid, but riffled (like a potatoe chip) so moisture can circulate within the Rabbit that window sits.
Holes for drainage, well, 3 ought to do the trick. maybe two, depends on the size of the window. remember air circulation is what will keep your window in shape for perhaps longer than you live, if built properly, so make sure the moisture that does happen to get in, can get out too.
The whole air circulation thing is not for movement, its to allow the dew buildup which happens mainly in winter, when cold (dryer) air meets the warm moist air from the inside (of your house) and they will meet somewhere usually in the middle of your window frame. That you can do nothing about, just provide an escape route for the moiture so your window does not form mold or rot, which is bad. We have all seen what happens to a cold beer bottle on a hot day, dew water or condensation builds up where the warm air and cold air meet.
Ok if you have any more questions feel free to ask…. I hope I have not bored anybody with such a long post. Especially if you are looking for good tips on installing the window or something.
Let me know what you think!
