WhisperClip Testing

WhisperClips improve sound isolation by decoupling drywall from your room framing. Install WhisperClips directly to ceiling or wall framing using standard screws . Snap 7/8" Drywall Furring Channel into Whisperclip to decrease the conduction contact area and increase the flexibility. Fasten standard drywall following local building codes. The combination of increased resilience and the mass from the drywall create a powerful ally against noise. See the official lab results below.
