Xylofon Acoustic Profile

Designed and manufactured in the Italian alps by the world-leading wood construction specialists, Rothoblaas, Xylofon is built to provide world-class soundproofing for timber frames.

The resilient profile can be easily processed and installed using the most common site tools; its reliability over time is ensured by the homogeneity of polyurethane, whose monolithic structure ensures watertightness and the absence of subsidence over time.

Extremely chemically stable and without deformations over time, it ensures durability without the function losing effectiveness. The low thickness of the 5 versions supports a wide load range (up to 6 N/mm2) without affecting design choices, allowing deformations up to 1 mm of thickness. The 5 different levels of shoring allow the properties of the product to be retained even under larger load - for example, ground floor versus first floor, versus second floor.

Tested in the FLANKSOUND PROJECT by the Industrial Research Centre of the University of Bologna in accordance with the standard EN ISO 10848; tested also by the ETH Institute of Zurich for fire resistance, which reaches performance equivalent to an EI 60 solution without the need to use further fireproof sealants. Product free of VOCs and harmful substances. Suitable also for application on LVL panels.

SOUND INSULATION AND LIVING COMFORT

In construction, sound is divided into two categories, depending on the mode of transmission:

• AIRBORNE NOISE: the medium carrying the sound energy is air;

• STRUCTURAL NOISE: the sound crosses the structure carrying the vibrations from room to room, even when not contiguous.

Timber structures, like all light constructions, do not have high acoustic performance at low frequencies, in particular with regard to sounds of impact and the transmission of structural vibration by the components making up the structure itself.

It is necessary to stop the spreading of vibrations in order to obtain a reduction of noise transmission. To do this recourse is made to resilient products used according to the principle of desolidarisation: that is the construction technique or action which keeps elements isolated or separated when contact would allow the transmission of vibrations and therefore noise.

By resilient products is meant elastic separating layers between rigid elements whose main feature is to prevent the transmission of vibrations in the building structure (e.g. impact or noise from footsteps) to its various partitions. Working at this level of the structure means being able to solve the problem at the source, allowing greater flexibility and tolerance during processing and modification of the subsequent layers, such as thermal and acoustic insulation or coverings and various kinds of dry linings.

The products have been highly tested, and come with a wealth of technical information behind them:
