[Closed] Triple glazed windows

Loads. The frames also play a big part though.

If you just get double-glazing, then get as wide a thickness spacer bar as you can fit, as increasing the gap inbetween the panes also helps.

however be aware that over 16mm cavity is detrimental the insulation of the unit...

Noise wise...

it's not as simple as x amount better, there's an awful lot of variables in glass type, spacer bar, glazing system, fame type etc...

I never spec triple glazing for noise control, always use either heavyweight double glazing such as 8-6 or preferable pilkington optiophon.

Standard triple glazing has quite a few drawbacks as if the panes are all a similar thickness they suffer from a coincidence dip at the same frequencies impacting on their effectiveness.

And that ladies and gents is why this place is so bloody good. Lots of opinions interspersed with the odd fact.

They cut out a lot, but it's my 80's built wooden and jablite then felted/tile hung dormers that let the sound in.
The reason I had triple installed is for heat/comfort. The surface of the inner pane is a few degrees warmer so I don't get the convection draught when sitting near the window., the sound insulation was secondary, first thing I noticed was not hearing the wind/rain so much.
If it's below freezing I can feel a draught but if I pull the blind up a few inches it disappears.
People who don't have triple say they are darker but I cannot tell that they are letting less light in, the difference must be tiny. I wouldn't buy double glazing when triple was only a few £'s more.
