Glass door and soundproofing?

[snowjim]

Hello,

We are going to install a glass door as follows in the basement:



The door will be placed between 2 larger rooms and the idea is to give a sense of space even though there is a door there.

It would be a plus if it could stop some of the sound waves, but I have a suspicion that single glass absorbs very little? So the question is whether it is worth it to buy a frame with built-in silicone insulation?

Is there a gap between the threshold & door leaf? If so, the sound passes through there, that's my experience at home.

Absorb or screen off?
The most important thing is that it becomes airtight, then you will notice a difference. It makes a difference either way, but it gets better the tighter it is.
What is the sound reduction value of the door? It is usually listed in the data sheet.

If so, the sound passes through there, that's my experience at home.

There will probably be a small gap of a few mm, in that case I will seal it but with what I don't know yet as it is after all a door frame that likely moves somewhat.

Absorb or shield?
The most important thing is that it becomes airtight, then you will notice a difference. It makes a difference regardless, but it gets better the tighter it is.
What is the sound reduction value of the door? It's usually stated in the datasheet

I will check with the manufacturer about what the sound reduction value is.
