Triple glazing - does it actually reduce light?

ruelle

I'm on the fence about getting double or triple glazing. I've been given a quote for triple that is not much more than double. It seems like triple is great for noise reduction and extra warmth but I'm worried about it not letting in as much light (which I've read is one of the main disadvantages of triple). Does anyone have triple glazing in their home? Does it reduce the natural light?

Clear float glass passes around 80 to 90% of light according to Pilkington's

No. Not that you'd notice.

If you weren't told in advance it was triple, you wouldn't know.  

(TG bifolds - looks just like glass in terms of voo and light.)

Relative to single and double, yes.

But the difference would be quite subtle.  And could potentially be counteracted by painting walls a lighter colour.

I am not sure how much extra warmth it would keep in, probably only a few per cent at most, and even that would assume the house was very well insulated apart from the windows.  It should help if you have problems with external noise though.

I do have problems with noise which is why I was considering it but I'm just worried about the light reduction.

What's there at the moment? PVC DG units?
If the new windows are also PVC, then possibly the frame thickness will be greater to handle the extra weight? 
In general, tho', if you didn't know, you wouldn't be aware. My concern was about image distortion and reflection. No such issue.

Crappy wooden frames with single glazing so I'm replacing everything including the frames so that shouldn't be an issue.

The reason I asked was because thicker frames = smaller glass area, and that could feel less lighty.
But I wouldn't worry about the extra sheet of glass. Plus, any noise reduction sounds good for you?

I was in a similar position a few years ago, triple for not much more than double. I went with the triple and it's great, hardly noticeable light wise but great noise wise.

Yes, I was really surprised that it wasn't that much more than double glazing.
