Just 1.2mm thick Xetal 8000 Membrane is made from a patented formulation process based on synthetic rubber with special fillers and other components to provide truly outstanding acoustic properties. As a sound reduction membrane, it far exeeds the noise reduction of other traditional materials such as plasterboard, mineral wool and foams.

Xetal's high performance membrance's convert commodity products into high performance sound reducing laminate material for a wide number of applications.

Acoustiquilt is a laminate of mineral wool and Xetal 8000 Membrane. Specifically designed to resist the passage of airborne sound through partition walling, roofs, ceilings and floors. The quilt can be covered on one or both sides to give a moisture barrier for sound attenuation curtains where moisture ingress is a consideration.

NOTE: It must be fully understood that good building practice is most important, simple things like staggering electric sockets and switches, ensuring that there is a good seal to all joints and where pipes and cables pass through walls a good seal is achieved are all important.

The results of noise pollution vary from mild irritation to severe stress and have a detrimental effect on people's health and quality of life.

This problem is particularly acute where there are shared homes and in apartment blocks where the scale of noise has increased dramatically in recent years to become one of the 20th century's biggest environmental and building problems. Now the government is encouraging developers to build at higher densities the issue is even more important.

To combat these problems of noise pollution the government has introduced new legislation. The new standards have been published in a new Approved Document-Part E (England and Wales) of the Building Regulations "Resistance to the Passage of Sound", which came into effect on July 1st 2003 for refurbishment and July 1st 2004 for new build.

The government is tackling the problem by introducing more robust building standards to improve the soundproofing in new homes and schools for both new and refurbishment projects in England and Wales.

The aims of the Part E legislations are:

• To improve acoustics and therefore sound privacy between residential buildings.
• To improve the sound reduction of internal walls and floors within the home.
• To improve the sound reduction between rooms and in common areas in hostels, hotels, residential homes, schools and hospitals etc.
• To re-address sound performance criteria, taking into account day low frequency sounds such as TV, Stereo etc TV was considered to be the main cause for complaint in the majority of the 180000 complaints about noise per year received by the Local Authorities

Xetal 8000 Membrane provides a simple solution to ensure compliance with the regulations. The message is clear, airborne sound is to be controlled and regulated with costly eradication where failures are revealed by Building Control or UKAS approved test centres.

In order to achieve the new Rw figures and be comfortably within the control limits, use can be made of existing building methods with the relative cost implications both for additional materials, additional labour costs and reduced floor area. Alternatively Xetal 8000 Membrane provides a solution that is lighter, less labour intensive, and achieves Rw values that exceed the requirements.

Xetal 8000 Membrane has an Rw value of 22 dB that when used as a laminate on plasterboard and included in the construction of a standard 75 mm stud internal non-load bearing wall, will provide 59 dB with a weight factor of just 20.99Kg per square metre when using 12.5mm plasterboard.
