Hello everyone
The topic of "glass patio roofing" has already been discussed several times in this forum. It has become clear that such a glass roof only works well in summer with external awnings/shutters; otherwise, it gets unbearably hot. So far, so good.
Now, to all owners of such glass roofs with external shutters: how comfortable is it actually to sit under the glass roof with the shutters down during the (peak) summer? Is there really no heat buildup? Or does it still become unbearable under the glass despite the external shutters?
Our architect is currently strongly advising against a glass roof because it seems that—even with external shading—it is hardly bearable underneath during summer. He recommends a gravel roof instead.
For me, however, the advantages of a glass patio roof with sun protection shutters are obvious:
What do you think? Many thanks for your experiences.
PS: As an alternative, for example, a louvered roof could be installed for shading. This is said to be waterproof, and in peak summer the louvers can be easily adjusted horizontally to let warm air escape at the top, preventing heat buildup underneath. Does anyone have experience with this? I would be very grateful for any input.
Best regards

For me, however, the advantages of a glass patio roof with sun protection shutters are obvious:
- No darkening of the living room due to fixed shading (wood/gravel roof), especially in winter.
- Extremely flexible: without lowered shutters, it is still comfortable to sit underneath on colder (sunny) days (which is hardly possible with a wood or gravel roof because it simply gets too cold without direct sunlight).
What do you think? Many thanks for your experiences.

I’m also interested in how hot it gets under the glass roof.Hopefully, I can report on that this year. The patio roof is scheduled to be built in spring.

If anyone wants, I can also send a few pictures. Even though we have already made our decision, I would like to take advantage of that.

Hello everyone,
Last year, we treated ourselves to an aluminum glass louver roof with a folding glass system, and we are very impressed.
Especially now in winter, when it’s so cold outside, we can sit in our cold conservatory that stays between 18-20°C (64-68°F) on sunny days.
But you need to be careful. There are many suppliers online offering the same system, but most are just distributors, not manufacturers. There are not many companies that can actually produce this kind of system. In Germany, I believe there are only four, and not all use glass for the louvers—some only use twin-wall sheets, which was not an option for us due to the drum effect.
Regarding light transmission, we haven’t noticed any loss because you can choose between clear glass and opal glass. As for heat during the peak of summer, it’s still bearable underneath because we can open the louvers, allowing the hot air to escape from above.
Overall, we are very satisfied so far and can definitely recommend such a roof.
Price-wise, it was quite affordable if you buy directly from the manufacturer and have it installed.
If anyone is interested, I can also send some pictures.
Best regards,
Remzi Even though it will be a few months before then, we would also be interested in some photos to get a better impression.

Deliverer28 Feb 2018 14:27We also have an unheated conservatory, so far only with internal shading.
When it gets hot, the side walls are opened, and then it is no warmer inside than under a sunshade.
A light-blocking external shading undoubtedly improves this further – however, at temperatures where this would be necessary, we are no longer outside anyway, but inside the house or in the water.

For our south-facing terrace, we initially installed a plastic roof. That didn’t work well in the summer; its function was more like a "fall/spring rain cover." Overall, it was rather unnecessary and almost pointless. Of course, you can hang something underneath, but that costs money as well. Since the roof of the attached carport needed to be redesigned anyway, we decided on metal roofing with anti-drip treatment. Yes, the window and the room behind the canopy are a bit darker now. But in summer, it’s simply cooler underneath, and the sun doesn’t blast through the roof.
To be honest: when the sun is high enough to come through the roof, you’d rather sit in the shade. Alternatively, not everything is covered, so you can sit 3–4 meters (10–13 feet) further away and enjoy the sun.
