Acoustic Insulation

High quality insulation materials are required to meet the acoustic standards of Approved Document E of the 2003 edition of the Building Regulations for both airborne and impact sound reduction through intermediate concrete, modified beam & blocks, steel-concrete composite and timber floors.

Cellecta

Cellecta FIBREfon

FIBREfon high performance resilient layers are made 100% recycled materials. There high compressive strength makes them ideal for kitchen and bathroom applications, under screeds and where lightweight partitions are to be built off the floor finish.

Cellecta Screedboard 28

Cellecta Screedboard 28 Screedboard 28 acoustic treatment consists of a grey, ultra high density, recycled calcium sulphate, dry screed sheet, with interlocking edges bonded to a high density, recycled PES fibreboard. Its low thickness, high acoustic performance and ability to accept ceramic tiles, without the risk of cracking associated with timber based acoustic products, makes it the ideal treatment for timber separating floors.

Alternatively, the board can be laid on structural concrete floors and is a BBA verified RD FFT4 compliant treatment.

FIBREfon CHiP and MDF

FIBREfon CHiP and MDF acoustic treatments combine the benefits of FIBREfon with a moisture resistant t&g flooring board. The systems' high compressive strength enables lightweight partitions to be built directly off the floor treatment. Each system exceeds the demanding requirements of Part E and are BBA verified, Robust Detail FFT5 compliant, when used to reduce impact sound transmission through concrete separating floors.

Eliminating Acoustic Flanking

The acoustic efficiency of the floor can be adversely affected should acoustic bridging between the floating layer and surrounding structures occur (known as flanking transmission). All floor finishes must be isolated from the surrounding walls, services and other structural elements. To combat acoustic flanking, Cellecta manufactures an extensive range of flexible extruded polyethylene edge strips to suit specific systems.
