Acoustic Floor Slabs

For use as a resilient layer in the acoustic insulation of separating floors

Description

Acoustic Floor Slab and Acoustic Floor Slab Plus are dense, compression resistant, non-combustible, rock mineral wool slabs that have been manufactured specifically for use as a resilient layer beneath chipboard and floor screeds.

Application

Acoustic Floor Slab is for use as a resilient layer in the acoustic insulation of separating floors.

Acoustic Floor Slab meets the requirement in Approved Document E (England and Wales) for a resilient layer under a floating platform to be mineral wool, 25mm thick with a nominal density between 60 and 100 kg/m³.

Acoustic Floor Slab also provides a weighted reduction in impact sound pressure level ( Lw) of at least 17 dB when measured in accordance with Appendix 5 in Section 5 of the Scottish Technical Handbook.

Acoustic Floor Slab Plus is an extra high density slab, with a nominal density of 140 kg/m³, for the acoustic insulation of separating floors to meet the requirements of a floating floor treatment in the Robust Details (England and Wales E-FC-1, E-FC-2 and E-FS-1).

Certification

Acoustic Floor Slab and Floor Slab Plus are certified by BBA Certificate 97/3433.

ECOSE^® Technology

Knauf Insulation mineral wool products with ECOSE^® Technology benefit from a revolutionary, bio-based, formaldehyde-free binder technology, based on rapidly renewable materials, instead of petro-based chemicals. It reduces embodied energy and delivers superior environmental sustainability.

The technology has been developed for Knauf Insulation’s glass and rock mineral wool products, enhancing their environmental credentials without affecting the thermal, acoustic or fire performance. Insulation products made with ECOSE^® Technology contain no dye or artificial colours – the colour is completely natural.

Acoustic Floor Slab and Acoustic Floor Slab’s manufacture has a low impact on the environment and is classified as Zero ODP and Zero GWP.

Moisture Resistance

When exposed to 90% relative humidity and 20°C Acoustic Floor Slab and Acoustic Floor Slab Plus absorb less than 0.004% of moisture.

Handling and Storage

Acoustic Floor Slab and Acoustic Floor Slab Plus are easy to handle and install, being lightweight and easily cut to size.

Acoustic Floor Slab and Acoustic Floor Slab Plus are supplied in weatherproof Supakube packaging, on non-returnable wooden pallets. This makes them very easy to unload and ideal for outside storage, which frees up internal stock space.
