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.

If the heat from a glass roof can escape through the sides and front, the temperature inside will not be significantly higher than the outside, even with internal shading. For darkening a glass roof with a supporting timber structure: Not noticeable indoors. Feel free to request a photo via private message.
One more small addition:
Although we used light-colored stones, our terrace (west side) heats up considerably in the summer from midday onward. In the afternoon, it can sometimes be unbearable. I would actually expect that extensive shading would reduce the amount of heat stored in the stones and the adjacent exterior wall. As Nordmann already mentioned, the roof is open on the sides, allowing the heat to escape.

RäuberHotzen3 Apr 2017 11:01I assume you didn’t build your patio roof before winter?
My wife and I are facing the same question and, after much consideration, decided to go with a glass roof with shading.
The main reason, as for you, was the lack of light on the “not high summer days.” Since there are more of these days than actual high summer days, we chose this option and plan to simply place a large fan under the roof.
We haven’t started looking for an installer yet, but we have often seen that it is possible to leave a “ventilation gap” at the top to allow warm air to escape.
If anyone has a glass patio roof, maybe they can share their experience...?

meister keks3 Apr 2017 23:17If you have the budget for the aluminum slats and you like them, I would go with those since they offer flexibility. Open, half-open, depending on the sun, is ideal. For us, a regular glass roof will be sufficient.
Hello everyone,
Last year, we installed an aluminum glass louvered roof with a folding glass system, and we are very pleased with it.
Especially now in winter, when it’s so cold outside, we can sit in our cold conservatory warmed to 18-20°C (64-68°F) on sunny days.
But you have to be careful. There are many providers online offering the same system, but most of them are just resellers, not manufacturers. There are not many companies that can actually produce something like this. In Germany, I believe only four companies manufacture these systems, and not all of them use glass louvers; some use double-wall polycarbonate sheets, which was not an option for us because of the drum effect.
Regarding light transmission, we didn’t experience any loss since you can choose between clear glass and opal glass. As for the heat during midsummer, it’s still comfortable underneath because we can open the louvers to let the hot air escape upwards.
Overall, we are very satisfied so far and can definitely recommend this type of roof.
The price was quite reasonable when buying directly from the manufacturer and having it installed.
If anyone is interested, I can also send some pictures.
Best regards,
Remzi
