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!

One part of the unit may only have a height of 2.3 m (7 ft 7 in) from the finished floor level to the exterior roof surface.
It is better to place this in the north section of the building in the design. The bedrooms are also better located in this area, which then has a clear ceiling height of only 2 to 2.2 m (6 ft 7 in to 7 ft 3 in) underneath.
Living, working, and dining rooms should remain in the southern part, where the shed roof rises and the clear ceiling height is greater than 2.4 m (7 ft 10 in).
Alternatively, I am considering minimizing the roof construction height by using aerogel insulation instead of glass.

How do you plan to shade the glasshouse in summer? Sleeping in a greenhouse doesn’t sound very comfortable to me.
