Yes I see that but, when i measure new windows, i check the sizes inside and out...Even allowing for them measuring outside, they are poorly fitted!

Mr_Skint_2

you cant measure a window in and out as the sizes would be different
now c'mon man dont bring me down with those negative vibes. :rotfl:

Silicon eis only used to bed the glass in on wooden double glazed windows

AAAAAAAAAAAARGH. No it is not!!! To bed double glazed units into a wooden frame, you should use butyl putty. Getting units out of a wooden frame that have been 'stuck' in with silicon is a horrible job and really difficult. Butyl is made specifically for bedding in DG units.

I've come accross silicon being used many times (and I really hate it). No glazier worth his salt would even consider doing this.

Hang on Guys dont forget the head of the reveal is made of wood thus adding

This is why using an extention header would take this into account and make the frame look even all around from the inside.

Mr_Skint_2

I agree a big tub of, off white Butyl Mastic Putty, bed up the frame, stick unit in.
then a bead of low modulus silicon between the galss and wood frame then tack the beads on.

Yeah about a 15mm should do it.

The first bit is right, but if you put silicon behind the beading before fixing. It will be almost impossible to get it off without breaking it. Bed the unit in with butyl, clear off the extra from where the beading goes. Fix the beading, then a very tiny pencil line of silicone where the glass and beading touch should be used. This is the proper way of glazing to wooden frames.

My guess from the photo is that nearer 30mm would be better. But this is only a guess from a not very clear photo. It's almost impossible to tell exactly without seeing and measuring myself.

Fensa want it done that way now, (T*TS) How we get them off is to slide a
facing knife inbetween the frame and bead then run a stanley knife
inbetween thus cutting the silicone.

Two main reasons for this is.
The rain can run off the window and go down behind bead.
No visible silicone on the glass, easier for cleaning after installation.

You measure outside, then check the inside measurement aint to diffferent, and provided u measure from the lintel to under the cillboard, you get a good indication of any differencem and whether to make the frame thicker
