Internal Floors

The overwhelming concern of the designer when considering the internal floors of a dwelling is to ensure that the floor has the ability to support the dead and live loads that will be applied to it in the context of the whole structure of the building. Building Regulations determine the minimum standards for structure and fire resistance. Another important consideration is the spatial separation that the floors provide within a dwelling in both acoustic and thermal terms.

Quite reasonably, the occupier of a dwelling can expect there to be satisfactory acoustic separation between the various storeys within a dwelling particularly as bedrooms are normally separated from living rooms by floors. The acoustic separation provided by a new internal floor in new build dwellings is formally regulated in England and Wales by the Building Regulations.

The sound absorption characteristics of mineral wool make it ideal for use in modern buildings to comply with Approved Document E of the Building Regulations in England and Wales, Technical Handbook, Section 5 for Scotland and Technical booklets G and G1 for Northern Ireland. In addition, the thermal properties of mineral wool provide a secondary benefit of minimising heat loss, either between attached dwellings or between storeys within a dwelling.
