Noise has become one of the greatest environmental problems of our time.

Whether at work, in public buildings or in the home – hardly anything disturbs us as much as noise.

Although the acoustic insulation on external structural elements may be good, annoying noises inside the building can greatly impair the quality of life.

It is therefore essential that noise protection measures are consistently planned and properly carried out, both when constructing new buildings and when modernising existing ones.

Acoustic insulation in buildings means ease and comfort, but also privacy, intimacy and a sense of security. The increased appreciation of private living space is reflected in higher expectations. Nowadays, tenants and buyers expect enhanced noise control.

If it only complies with the legal requirements these expectations are left disappointed.

Unlike many other planning errors or construction defects, noise disturbance is usually not accepted.

Building acoustics and noise control are extremely complex issues. They depend on so many parameters that it is difficult to predict the acoustic behaviour of building services.

There are multiple sources of noise and many factors which influence whether and to what extent noise is propagated from these sources.

Two main types of pipe noise can be distinguished: the airborne sound and the structure-borne sound.

Airborne sound is sound that is transmitted through the air. In pipes the sound is due to the flow of water and it is propagated into the room.

Structure-borne sound, meanwhile, is sound that is transmitted through the building structure. It  can come from the pipe support or from the connection between the pipe and the building frame.

Other sound, such as reflected sound, can occur in technical ducts around the pipes.

To avoid or reduce this it is important to act at the source by insulating the pipes or decoupling the pipes from the support or from their connections to the frame. 

ArmaComfort products are highly effective, easy-to-install noise control products specially-designed for insulating rainwater and wastewater pipes.

In comparison to traditional products, the multi-layer acoustic insulation materials achieve greater noise reduction with thinner wall thicknesses.

Sounds from wastewater pipes and internal rainwater pipes are experienced as being particularly annoying.

The noise of falling water is transferred via unprotected pipes to wall and ceiling elements and from there to adjoining rooms. ArmaComfort provides highly efficient noise control solutions specially developed for this area of application.

As a closed-cell insulation construction on the basis of Armaflex, ArmaComfort reliably prevents condensation on the pipes.  

In comparison to traditional acoustic insulation products, ArmaComfort achieves a much greater reduction in the sound level with a thinner wall thickness.

The new materials have very good sound reduction and sound decoupling properties across the frequency range relevant for building acoustics – no matter whether they are installed on cast iron or plastic pipes. 

The products display very good fire behaviour: with B-s1,d0 ArmaComfort AB Alu PUR, and ArmaComfort AB Alu Plus achieving the best fire class for organic products in the European SBI test.

Furthermore, the attractive silver-coloured aluminium covering fits in well with metal-clad installations in areas where the pipes are visible.
