How Cement Particle Floorboards Work – Hush CEM 28 Overview
Hush Panel CEM 28 is our exceptional high mass acoustic floorboard, made from cement particle board and covered with our exclusive Hush Felt 10mm resilient layer. The particle board is made up of both chipboard and cement that has been specially mixed together to create the denseness required to tackle both impact and airborne sound performance within modern and lightweight structures.
Applying Acoustic Resilient Layers
Hush felt is a hard wearing, environmentally friendly felt that is manufactured from recycled fibres and is unique to Hush. These recycled fibres are knitted together through needle punching which is a high-tech method used to establish the thickness of the product, contributing to the endurance of the acoustic floor. Adding to its incomparable resilience, Hush felt also has a rot proof polypropylene layer.
What is are Cement Particle Floorboards used for?
Hush Panel CEM 28 was designed to meet the requirements to achieve legislation on site and guarantee performance criteria within contemporary construction. Contemporary construction such as; new build timber frame, cross laminated timber, steel frame buildings, offsite or modular construction is categorised as lightweight due to the frames generally being made from wood or steel. By adding high amounts of mass to the lightweight constructions, the airborne and impact noise performance is increased, something that doesn’t occur when using only a standard acoustic flooring.
How to Install
The tongue and groove design of the board makes for quick and easy installation due to its interlocking edges, adding to a stable floor surface to carry many floor finishes.
Used to achieve Building Regulations in the UK, inclusive of Document E compliant (England & Wales), Section 5 compliant (Scotland), Part G compliant (Northern Ireland) and also used to exceed minimum performance criteria of the Building Regs for planning approval or BREEAM, along with being a robust details compliant system or achieving Robust Details performance standards, Hush CEM 28 makes for an excellent choice for high rise buildings, such as flats and hotels and is also ideal for modular and offsite construction projects.
This product is a direct alternative to other dry screed board products on the market and will achieve the same acoustic performance.
Along with the many benefits already described, the Hush CEM Panel 28 also carries a Class O fire rating which is highly fire retardant, meeting building fire regulations.
Hush CEM Panel 28 has been tested for its Acoustic performance and the measure of effectiveness is shown in decibels (dB). The higher the transmission loss, the better the barrier to the passage of unwanted noise.
Airborne and Impact are the two types of sound insulation found within buildings and the results of the Hush CEM Panel 28 when used correctly, over the floor structure, with a suitable ceiling treatment and all flanking paths removed are:
