Before you go about soundproofing glass doors.
Home theater sound proof sliding door.
If the room which has the sliding glass door or french doors is a home theater recording room or media room there is very little you can do and i would suggest that you consider another room for the purpose or replace the doors with traditional wooden ones.
I will also be talking about other methods to soundproof a sliding glass door.
So how do you soundproof a home theater room.
To soundproof a door make it structurally strong enough to block noise by replacing it with a solid core door or by adding mass loaded vinyl soundproof blankets and panels to the existing door.
There are several ways to soundproof a home theater room and they rely either on adding mass or decoupling the walls.
Soundproofing this door gap is possible and it will help a lot.
Soundproofing a sliding door is much more difficult than a traditional swinging door.
I m not a soundproofing expert per se but i ve seen how this gets handled in a lot of serious theater installs and it s often done with a combination of a heavy soundproof door that s very tight to the frame and often sealed and it will typically have a raised threshold on the bottom.
Because it was a home theater and i did want to ensure the isn t sound leaking in any way i got the automatic door bottom instead of the door sweep.
1 make sure to seal all the cracks.
