Should triple gazing keep heat out in summer

3rdDegree

I'm obsessed with keeping warm in winter and my wife is the opposite and is only interested in keep cool in summer!

Anyway, she has noticed that these warm mornings, when the sun is shining on our new triple glazed windows, the inside pane of the windows is very warm to the touch whereas the outside one is a lot cooler. She thinks there is something wrong with the windows. Are they supposed to insulate from heat in the summer? I think they're fine, but she just wont be told! Can you let us know and maybe I can get a decent night's sleep without her fretting to me about them!

Thanks

The 3G will keep the heat out BUT If the sun is shinning on them of course there will be solar gain.

It also depends on what coatings the glass have, there are some that will keep heat in the house and others that will reflect sunlight out.
As for solar gain, you could always fit awnings outside to shade the openings during the summer.
I made the mistake of fitting black venation blinds and these turned into "radiators" heating up the room.

In case anyone is interested: We did some more experimenting with this and it turns out that the while blind on the window is reflecting light back against the inside pane heating it up. If the blind is left up, the pane does not become anywhere near as warm.

Thanks all.

I have a related question...

My living area has too much solar gain in the summer due to my windows being way too big...

Long shot but wondering... Is there any coating that can be added to the outside of the windows that would reduce this solar gain?

I'm actually thinking about building something similar for my south facing kitchen windows, but making them permanent.

you can apply a film to your glass to prevent/reduce Solar Gain

you dont want to reduce the solar gain permanently because you need it in winder.

a solution like a bris soleil above allows you to retain both summer shading and winter heating.
i suggested something temporary as i dont know the design or space available

There's very little solar gain in winter and the film will help insulate to keep the heat in.

You'll be surprised at how warm my black blinds can get in the middle of winter, also the sun can shine on a large area of floor and the warmth can be significant.
