Hello. Currently, we are considering options to avoid sawing off doors (because of soundproofing). We already know all the alternatives (frame ventilation, U-seal on the door, etc.). We are now interested in the "professional" solution of soundproofed overflow elements (room transfer grilles) for wall installation. Has anyone installed such elements and do they really make a difference regarding soundproofing? Perhaps someone can also name a manufacturer you are satisfied with. I have researched the following, but unfortunately do not know any of them... ·Durrer ·Kiefer ·Lindab ·LTG ·Schako ·Swegon ·Systemair ·Westaflex
