Hush Retrofit Panel

Hush RetroFit Panel is an innovative thin, multi-purpose board that contains high levels of mass to enable acoustic improvements in existing buildings affected by airborne noise issues.

With a thickness of only 15 mm, this board has been designed to reduce airborne sound transmission without adding significant depth to existing floors, walls or ceilings.

The Hush RetroFit Panel is sustainably designed and manufactured using lightweight cardboard with a unique sand infill to add mass. When coupled with an impact layer on a floor, the panel will significantly improve impact sound reduction too.

It is a versatile product for use on separating floors, walls and ceilings and it is particularly well suited to treatments designed to address nuisance noise from neighbouring spaces, rooms or properties.

Features and benefits:

• Sustainable and natural product - made from cardboard and sand.
• CE marked 13/0411 - award winning product.
• Easy to install - manageable sized sheets.
• Suitable for retrofitting due to being thin and easy to install.
• Adds mass to lightweight structures.
• Can be used with underfloor heating systems.
• Suitable for reducing noisy neighbour complaints.

Acoustic performance:

• Up to a 23 dB airborne improvement achievable.
• A minimum 19–32 dB improvement (if used in conjunction with the correct resilient layer).
• Rw lab test airborne figure recorded of 38 dB.
• Lw lab test impact figure of 22 dB.
