I'm finalising build plans and got a quote for UV tinted glass. The price is fine but these graphics have me curious/concerned about the blocking of light.


Clear


Clear double glazed


Grey tint

I want to avoid fading but also don't want it to be too dark inside. The verandah will probably cut most of the direct sun but a couple of windows aren't covered. Don't want it to look weird with some grey and some not grey windows though.

Any thoughts?

You can get electrically controllable film than you can make darker or lighter as desired.

I would argue that tinted glass has a minimally noticeable effect on inside light, you will appreciate the tint in the hot summer months and not notice a lack of light in wintry months

 

Common practice is to use tinted glass on exterior pane and a Low-E glass on inside pane of IGU, the 

 

IMHO the UV and heat transfer properties are the critical aspects to worry about


Hmm, what to write...

To avoid fading you want to get laminated glass

 

"Grey float" (the tint you are thinking of) will not appear to make the house dark, it will however remove the glare and make the house difficult to see into during the day... Its great

 

 

 

I have had grey float, laminated, argon filled, low-E, Toughened for about 8 years... not a sign of fading

 

 

 

the graphic you have shows 20% UV, it may as well be 100%, Laminated will drop it to 1%

I was all for it until I saw 45% light entry and that sounds like not much.

Honestly it sounds like it blocks lots of light... but it doesn't appear that way

 

 

 

you don't even notice until you open the door

Have you looked at triple glazing options? I believe the heat loss is far less, and it seems to becoming more standard  in Europe. Also you should go an see some previous work they have done with grey tint, to make up your mind. I have seen houses with a mix of tinted and untinted glass . You don't notice it too much when walking around, but it is very noticeable in photos of it.

It's a relatively low cost build of a small bach/granny flat type dwelling so will probably run with the grey tint double.

Thanks for the opinions, much appreciated.

I know every time you look there is something better and more expensive, but if it is a small build at least look at what laminating will cost ... it will save you worrying about fading, and its quieter , and will stay together like a windscreen if hit with stones from the mower etc

Laminated is affordable so I think I'll do it, now just got to decide whether to do tint as well or not :-)

Do you actually need double glazing? If you want to keep costs down and your wall R values are high enough you may not. If you use Design Navigator, you will be able to see if it is needed. Also depends on where it is being built.

 

The benefits of double glazing is less condensation on glass, although you may get it on frames instead. Laminated glass can still get condensation from my experience with it.

Price isn't so much a motivator as doing it once, doing it right. Pretty keen to double glaze as the done thing these days.

Supplier has now advised against combo of tint and laminate - something about heat build up in the unit if part of it is shaded and part of it is not causing the laminated to crack.

My priority is UV blocking rather than privacy, glare reduction, heat blocking and I do want natural light inside so laminated it is.
