Hello everyone,
I am currently planning to add a roof extension to a multi-family building to create a nice home for myself.
Due to building regulations, part of the planned sloped roof must be constructed as a post-and-beam (mullion-transom) glass structure.
The reason is that the roof thickness in that area is only allowed to be 20cm (8 inches), which still provides enough clear ceiling height given the maximum permitted building height.
This glass roof will then transition into a glass facade, similar to a conservatory. It will be quite large, likely spanning the entire room width and about 2 meters (6.5 feet) deep.
The structure will span the entire side of the building, with all three bedrooms located underneath. Now I am wondering whether a sound-insulating, heavy triple-glazed laminated tempered glass configuration would be sufficient to adequately reduce rain noise, allowing for comfortable sleeping.
I understand that both the loudness and the sound of rain can be perceived very differently by individuals.
Perhaps there are opinions, experiences, or even actual observations on this topic.
Thank you all!

Schorsch_baut16 Nov 2023 18:16My parents have a 50 sqm (540 sq ft) conservatory with a glass roof. The rain is so loud that during storms and heavy rain, it’s impossible to sleep in the adjacent bedroom. A window cleaner comes every three months to clean the roof. And yes, even the internal shading doesn’t help against the heat when the sun is shining.
But it’s always amusing to read about the architectural tricks some homeowners come up with to bypass building plans.

A full storey is not permitted. At the same time, the space beneath this area must qualify as living space, meaning it needs to have a clear ceiling height greater than 2.0 meters (6 ft 7 in). A conventional roof with sufficient insulation cannot be realized with a thickness less than 30 cm (12 inches). Unless someone has a creative idea 🙂 Expensive aerogel insulation panels are another option to consider.Sandwich panels with a PIR core? That might just be possible including the structural framework – there are various suppliers, ranging from "trapezoidal sheets" for industrial buildings to designer roofs with matching gutters, skylights, and so on.

But it’s always amusing to read about the architectural contortions some homeowners come up with to circumvent building plans. Okay, these are actually more significant counterarguments, thanks! Well, if I can create €270,000 worth with a few considerations, then it’s not just for fun for me. For that amount, I probably work longer at my job than the hours spent pondering and scratching my head here. I do find it unfortunate that these considerations don’t come from the architect and that I have to bother you all here 😉

That should just be possible including UK (underside) – there are different suppliers, from “trapezoidal sheets” for industrial halls to designer roofs with matching gutters, skylights, etc. I just did a quick search, this seems like a good option. Since the roof is barely visible anyway, it probably doesn’t look too bad visually. What does "UK" mean?
Substructure.
The thinnest option is probably vacuum panels. However, they are expensive and require good protection—I’m not sure if corrugated metal sheets would be sufficient. Penetrations are also more challenging with them. But they insulate with 20–30mm (0.8–1.2 inches) almost as well as 160mm (6.3 inches) EPS 035.

That might be true for you, but it’s not the case for everyone... There are people living under airport flight paths, next to railway lines where high-speed trains or freight trains pass by, near highways, or in cities along main roads with tram tracks... yet they all manage to sleep; people get used to a lot of things...
I can’t sleep in spa towns where nights are completely silent. I miss the constant background noise I’m used to as a city child.
For our little daughter, we always play rain sounds on YouTube... she falls asleep quickly and peacefully with them; the sound of rainfall is very soothing.
Not everyone is a nail, so it takes more than one hammer to solve problems.
