Anyone with triple glazing here?

I'm thinking of getting it as it's not much more expensive than double but I've read it reduces the amount of natural light that comes in. For those that have it, is it noticeable at all? My house is quite dark as it.

Why do you want it? We went with acoustic glazed double glazing as we are on a main road to cut down the noise instead.

I also have an issue with noise as I'm by a road (not a main one though).

We were advised that acoustic double glazing would be more effective for us. It's been a couple of years since we had it installed, but the glass panels were different thicknesses which reduced the sound waves. I imagine you could find a much better description on the internet!

Also note that building regs mandate trickle vents on almost all windows now, so you are paying for the glass and cutting a hole for the sound in the frame. Something to be aware of.

We have triple glazing, I didn't notice a difference in the light but it wasn't really much better for sound than double glazing. We didn't have to have trickle vents as our existing windows didn't have them, but we got them done over 5 years ago so things may have changed. It depends on what you're looking to achieve as to whether they are the right option.

We love
our triple glazing- we’re on a main road but in the country so it’s a fast A road and we can hear a thing

Would you it makes a difference to how much light gets in?

We had triple-glazing fitted in our old house, it only cost 10% more so made sense.
It replaced 30yr old Everest windows with no trickle vents so we decided not to have vents in the new windows. Never suffered with any condensation issues as we always ventilate.
A definite reduction in noise and and I am sure they helped with insulation.

Before fitting, lots of people (companies unable to provide triple-glazing for one!) said we would have issues with the hinges etc breaking/sagging due to the increased weight, needless to say that in 8yrs (when we moved) we never had one such issue.

Thanks! Has it reduced the amount of natural light? Or is it not noticeable?

Sorry, your original question!😖

No, not in the slightest.👍

We also went for dummy openers on every pane so from the outside you could not distinguish which were the opening panes and which were fixed.
Supplier said that few opted for this as it was (obviously) more expensive but the finished job was far nicer and he said he wished more went for it as it really "finished" the job.

johnd2 · 06/12/2025 00:09

We went for sound reducing triple glazing so the panes vary in thickness and they work really well (A road outside)
No noticeable reduction in light not but the distance between the pans is a lot which makes a triple reflection at night if you have the curtains open.
No issues with the weight and we have a sliding one that is 2.4m high and well over a metre wide.

Phew! That's good - the light thing is the only thing holding me back. But I'm keen to have better insulation and the noise reduction that triple can provide.

Didn't realise you could get sound reducing triple glazing. Should look into this!

We have just had new triple glazed patio doors fitted to our kitchen. We said we didn't want trickle vents. I think you are incorrect about building regs.

Yes the outer pane is 6mm and the others are 4mm, and the gaps vary a little.
We got the normal triple on one of the side windows and the difference is massive!
The manufacturer in our case does a lot of commercial work, so all the stats about light transmittance, weight, sound reduction dB and more are in the data sheets so you can compare easily. The highest sound reducing one had an extra inward opening pane of glass, with impressive sound reduction, but it wouldn't be convenient.

housemonkey · 06/12/2025 15:48

We have triple glazing and never noticed anything re light. Someone upthread talks about trickle vents - we have MVHR (mechanical ventilation with heat recovery) and you don't need trickle vents if you that (but that was put in as part as a back to bricks reworking.

KathrynWheel · 06/12/2025 20:43

We have triple glazing in Aluminum clad wooden windows. No loss of light. We live in a countryside property with very little passing traffic so no noise issues to overcome. We opted for triple glazing for the increased insulation values. We decided to have trickle vents so that the rooms can be ventilated but they can be closed and I keep them closed most of the time.
No regrets.

Thank you for all the responses so far! It's so weird because I've been reading spec data on the light transmission value between double and triple - and that it's much lower than double.

Also those who have triple do you notice a difference is how much heat you feel from the sun that shines through? (apparently, it reduces solar gain...)

I don't know as we renovated the house when we moved in so have nothing to compare our triple glazing with. Our kitchen does get hot in the summer as we are S facing but we have an awning that we use on those very hot days to keep the sun out. Also have blinds inside the windows which we sometimes use.
DH did a test with some sort of machine to check insulation values (I think) and our windows are as insulated as our walls (which we insulated when we did renovation).

Thanks, @RosemaryandTruffle! If you can feel the sun coming through the glass then that sounds good enough to me! Was worried you might not be able to with triple.

Incorrect. All replacement windows in England and Wales since 2022 must have trickle vents to comply. Otherwise they would not be Fensa certified. If you have not had trickle vents added on a recent install they are not compliant.

Simonjt · 07/12/2025 21:06

We have triple glazing on the side of our house that doesn’t get a lot of light, they’re great, no reduction in light.

There are exceptions. I hate trickle vents.

Ours were replaced after then in our last place, no trickle vents required due to the type of window, we also wouldn’t have been allowed to fit windows with trickle vents to the building.
