Hello, came here looking for some suggestions on the best way to bulk up my booth door. Its a very heavy solid slab door but I definitely notice it being the weak point of the booth. Would love if I could achieve better isolation. Any suggestions on how to bulk it up effectively?

I also need to add a window...... Im looking into getting 2 of these and having a good 2" air gap between 1/4" glass. Any other suggestions?


Thank you!

Sorry! forgot the link to the window kit:

Isolation will be achieved through mass and a good seals. For your glass, again, mass (surface density) is the key. Assuming you don't have a room in a room (because you only talk about having 2" between two slabs of glass), you're going to be fighting against the mass law equation here.

The only other way to get way better results will be to build a room in your room.

To more directly answer your question about your door, make it have bank vault style seals where there are two or even three "steps" of seals. Add layers of MDF to the inside of the door. Make sure your hinges, door jamb and framing can handle the weight. Typically it is smart to add blocking between your wall studs around your door to add strength/stability.
