We've heard too many horror stories about poorly fitting doors and inadequate sound isolation. That's why Wenger engineers and acoustical experts have created an acoustical door that provides superior sound isolation. We've created an advanced split-frame design that accommodates virtually any wall thickness so every Wenger acoustical door fits perfectly. After all, even a small gap or imperfection can create enormous acoustical problems. Because our doors are pre-engineered, you'll be assured a high-integrity installation.
