I’m restoring a 1865 brick townhouse, and the “gift” I will eventually have this spring is the atelier being turned into my home office/studio/listening room.
It it will be insulated with Roxul: the walls with 6” and the ceiling with 14”. Instead of covering the Roxul over with sheetrock, I will cover it with a fireproof wide-weave canvas fabric.
The windows will have storms on the inside with a seal that is 12 times more efficient than conventional storm windows placed on the outside.
I will end up with a semi-anechoic chamber.
