FAQ

Sound Board & Acoustic Insulation Hanover NH — Common Questions

Massachusetts requires a minimum STC 50 for walls and floors between dwelling units in multifamily residential buildings under 780 CMR. Many quality Hanover buildings target STC 55–60 for comfortable sound separation.

Partially. Adding a layer of sound board over existing drywall with resilient channel and acoustic sealant can add 5–10 STC points without full removal. For significant improvement, a proper decoupled assembly with new drywall is more effective.

Acoustic wall systems in Hanover typically cost $3.50–$7.00 per square foot installed depending on the target STC and system complexity. Contact 857-214-2434 for a free estimate for your Hanover project.
