NRC 0.95 Glass Wool Acoustic Board 48K 50mm Panel For Drywall Partition Wall Sound Absorption

MYREAL 48K glass wool acoustic board is a 48 kg/m3 panel developed for sound absorption in partition walls. The open fiber structure of 6 micron filaments converts airborne sound energy into heat inside the cavity, reaching an NRC of 0.95 when the panel is fixed with a 50 mm rear air gap.

Technical Data

Application

Installed inside drywall partition studs, demountable partition systems and acoustic lining walls in offices, hotels, hospitals and schools.

• Drywall and demountable partition wall sound absorption
• Office, hotel and hospital room-to-room acoustic separation
• School and lecture hall partition acoustic treatment
• Acoustic lining behind perforated panels
• Partition cavity insulation combined with thermal and fire performance

Why This Specification

• NRC 0.95 measured to GB/T 20247 with a 50 mm rear air gap.
• 48 kg/m3 density gives the mass needed for partition sound reduction.
• Class A non-combustible - meets compartment wall fire requirements.
• No formaldehyde, benzene series or acrylic acid detected in the emission test.
• Rigid board stays in place inside stud cavities, no settling over time.
