APPLICATION OVERVIEW - TIMBER

Acoustic performance is the principle requirement in separating floors, with both sound insulation and sound absorption being important considerations.

The sound absorption characteristics of our Mineral Wool insulation solutions make them ideal for use in separating floor build-ups.

We have a wide range of solutions which comply with constructions registered in the Robust Details Handbook, providing compliance with sound related Acoustic Roll building regulations.

APPLICATION OVERVIEW - UPGRADE TO AN EXISTING TIMBER FLOOR WITH NEW CEILING

This detail provides a solution to upgrade existing separating floors for improved acoustic performance.

The existing timber joist floor is overlaid with hardboard and a new independent timber joist ceiling containing absorbent Mineral Wool is installed below.

The separation between the existing floor and the new ceiling prevents unwanted noise transfer via flanking, whilst the use of absorbent Mineral Wool further improves sound reduction.

APPLICATION OVERVIEW - UPGRADE TO AN EXISTING TIMBER FLOOR WITH NEW PLATFORM FLOOR

This detail provides a solution to upgrade existing separating floors for improved acoustic performance. The existing timber joist floor is overlaid with a new floating platform (min 25kg/m2) on a resilient layer of 25mm Rocksilk® Acoustic Floor Slab.

The use of absorbent Mineral Wool improves sound reduction, provides a solution as recommended for floor treatment 2 in Approved Document E and is for use where flats are formed by material change of use.

Why Mineral Wool?

  • Mineral Wool provides the best combination of thermal, fire safety and acoustic performance.

  • Mineral Wool insulation is the most effective insulant at reducing sound transmission and reverberations.
    The fibre matrix encourages the absorption of sound waves, converting them into heat energy, where other insulation types simply let the sound pass through.
