Hush Slab 100 Fitted to separating floors

How does Hush-Slab 100 reduce airborne sound transmission?

Hush-Slab 100 sound insulation slab is perfect for upgrading acoustic standards inside any residential, public or commercial buildings by providing an effective, safe and easy way to fill the cavities within walls, floors and ceilings.

The non-combustible, Class ‘O’ fire rated mineral wool slabs are specifically designed to reduce airborne sound transmission by disrupting sound transmission paths between rooms. Their use within the cavities, rather than having no insulation or filling cavities with inadequate PIR type insulation, plays a big role in delivering better quality buildings with greater end-user satisfaction.

Using Hush-Slab 100 within joists and stud work addresses nuisance impact noise – including sound from light switches and footsteps – as well as the sound from people talking, music and television in adjacent rooms. This makes it ideal for enhancing acoustic standards within homes, as well as in educational buildings, offices, healthcare facilities and many other commercial and public building applications.

Easy to install and cut to size, Hush-Slab 100 is a unique high-density sound-insulating slab available in varying thicknesses. In addition to excellent acoustic properties, the slabs also provide a high level of thermal insulation, with a thermal conductivity rating of just 0.035 W/mK for the 100mm option.

This is why Hush-Slab 100 is used extensively within refurbishment and new build projects to excellent effect. It is a key element within a wide range of tested Hush-Systems which represent an assured approach to upgrading acoustics, designed to exceed the current Building Regulation requirements of Part E (England and Wales), Part H (Scotland) and Part G (Northern Ireland).

Produced from non-combustible inorganic rock, it is defined as ‘mineral wool’ in BS 3533 and complies fully with the recommendations of BS 5422 and BS 3958: Part 5. Its durability is guaranteed for the lifetime of its installation as the material characteristics will not encourage the growth of fungi, mould or bacteria, nor does it sustain vermin, whilst being rot-proof, odourless and completely non-hygroscopic.

Fire performance is assured given Hush-Slab 100’s Class ‘O’ rating under the Building Regulations, achieving both a Class 1 spread of flame to BS 476: Part 7 and the required indices of performance of fire propagation to BS 476: Part 6.
