The brilliant intuition at the heart of Snowsound patented technology is based on the use of panels composed of material with variable density, which achieve selective absorption at different frequencies and thus optimise the acoustical environment notwithstanding the thinness of the panels. The absence of frames and seams and the unusual characteristics of the material used in the fabrication of the panels, render them extremely light, unobtrusive and adaptable to any environment.

1. The surfaces of the panel are coated with Trevira CS® polyester fabric firmly bonded to the inner wadding with which it forms a single body without a break. This property makes it possible to obtain a surface which, while visually appearing very soft, actually is resistant, difficult to tear or perforate.
2. High density polyester.
3. Medium density polyester.
4. Low density polyester.
5. Rigid edge.

ACOUSTIC PERFORMANCE “A CLASS”
Snowsound panels were tested in a reverberation room according to UNI EN ISO 354 standards obtaining “Class A sound absorption” to UNI EN ISO 11654 standards.

DECIBELS REDUCTION
Snowsound technology was tested in the semi-anechoic chamber at the University of Ferrara to measure sound attenuation according to the ISO 10053 standard. The measurements were conducted with a variety of configurations and demonstrate Snowsound significant capacity for sound attenuation. Performance was recorded at the various frequencies. The results of the tests represent another important design tool available to industry professionals.

SOUND QUALITY
The graphics and image show how the Snowsound panels affect the acoustics of a room:

1. notwithstanding the reduced thickness they do relatively well in absorbing the low frequencies (below 500 Hz), those that characterise deep sounds that are normally more difficult to dampen;
2. they absorb very well the midrange frequencies (between 500 and 2,000 Hz), those typical of the human voice and generally in all workplaces;
3. they tend to reflect, gradually absorbing less of the high frequencies (above 2,000 Hz), those which by their nature are already in large part absorbed by the walls, the furnishings and by the very presence of people.

The result thus obtained is a comprehensive, natural balance of sounds in the environment.

100% SOUND ABSORBING
The frameless design gives Snowsound panels a completely sound absorbing surface. The entire surface functions as acoustic correction; no other material is present to hinder its sound-absorbency or reflect part of the sound. The panels have the same aesthetic, acoustic and functional characteristics on both sides.

GREENGUARD GOLD CERTIFICATION
Snowsound products have received Greenguard Gold certification, indicating that they are low emitting products and do contribute to improve indoor air quality. Representative samples of products bearing the Greenguard certification mark have been independently tested and certified that they meet UL’s rigorous third-party Greenguard certification standards, which are among the most stringent in the world. To help reduce indoor air pollution, architects, designers, specifiers and building owners should choose materials and products that release the fewest possible pollutants (also known as low-emitting products). A great way to do this is by choosing products that are Greenguard certified, which means they have been screened for over 10,000 chemicals and do not emit high levels of chemical pollutants. Greenguard Gold certified products offer stricter certification criteria for sensitive individuals, such as children and the elderly, and are ideal for use in schools and healthcare facilities. Greenguard certified products also contribute toward credits within the indoor environmental quality section of the leadership in energy and environmental design (LEED) building rating system and the WELL Building Standard.

NO FORMALDEHYDE
Snowsound products have no detectable formaldehyde contents, tested according to the UNI EN 717-2.

ECO-FRIENDLY
In designing the panels and fabric, the goal was to achieve complete product recyclability at the end of its life. This is why the panels are made wholly in single fibre and 100% recyclable polyester, without the need to separate the external material from the sound-absorbing interior.
The plastic and metal components are also all single material and easy to take apart and recycle.
The panels do not contain felt or other natural materials that are often difficult to recycle.
Use of high quality products and manufacturing lengthen the life of the products and therefore, result in reductions in materials and energy.

Snowsound panels, when hanging from the ceiling, all bear the CE mark, according to the harmonised technical specification EN 13964 for use as a suspended ceiling. The technical data sheets and the performance declaration provided for these types of products allow customer to assess and choose the best technical solution depending on the installation needs and requirements

FIRE
The single material panel Snowsound, in its entirety, external fabric and soundabsorbing interior material, has Italian Class 1 and Euroclass B-s2, d0 classification as to reaction to fire. The tests were done on finished panels, composed of sound-absorbing materials upholstered in fabric on both sides, as required by law. This type of product is not conducive to testing the upholstery and padding separately.

EXTREME CONDITIONS
To simulate the influence of the seasons on indoor environments, Snowsound panels are subjected to a cycle of extreme weather conditions according to ISO 9142 standards in a climate chamber at -20°C (-4°F) to +70°C (+158°F) and humidity up to 90%.

STRONG, LIGHT & THIN
The variable density of Snowsound not only optimises the acoustic performance of the panels, but also creates a superficial protection shell which makes the panel more robust and less subject to damage, scratching, tears or other damages typical of porous or fibrous materials. Snowsound technology produces durable yet extremely thin, lightweight and easy to handle panels, averaging 3.4 Kg per sqm.

HYGIENE & MAINTENANCE
The absence of an airspace or cavity between the fabric and the sound-absorbing material significantly decreases the accumulation of dust, pollen or insect infestation. The seamless surface of the panel is easy to clean with appropriate detergents.
