How can I reduce the noise? How can I obtain sound insulation?

The complete range of STRATO® EVA interlayers is characterized by its excellent sound insulation properties. This makes it possible to produce laminated glass with higher performance than other interlayers on the market, minimizing the weight of the glass structure and maximizing the acoustic comfort of the environment.

In both residential and commercial environments, it is good to pay a lot of attention to the design of glass elements because they play a key role.

A laminated glass with STRATO® EVA film is able to ensure acoustic insulation of both the internal environment from external noise (e.g. building windows) and the external environment from internal noise (e.g. open-plan meeting rooms).

It is possible to obtain an important reduction in noise exposure in the private and professional environment, so as to improve the level of personal comfort.

The noise reduction performance depends on the type of interlayer/glass assembly used, which will have to be adapted according to requirements.

Noise is an acoustic sound that causes an unpleasant, annoying or intolerable sensation. It could become an important stress factor, causing difficulties in communication, reduced concentration, irritation, sleep disturbances. In an external Laboratory, Satinal commissioned specific tests on samples of laminated glass with STRATO® EVA film in different thicknesses. The tests were carried out according to European standards.

STRATO®, EVA, ADVANTAGES

What are the advantages of EVA film?

As a thermoset material, different from other thermoplastic interlayers available on the market, the chemical composition of the cross-linking EVA film allows the internal molecules to generate strong three-dimensional connections, thus ensuring an additional degree of protection for all architectural elements exposed to exceptional conditions, such as high temperatures, high humidity and extreme weathering conditions.

  • High transparency
  • High moisture resistance: EVA is more resistant to moisture than PVB at open edge. PVB suffers a high degree of delamination at open edge
  • Good sound insulation performance particularly in the higher frequency range compared with PVB. Given its high degree of soundproofing this is the ideal product for noisy areas.
  • High UV filtering: the 99% of UV filtering at 380nm wavelength is an indication of its suitability to protect from sun beams.
  • Lower processing costs: EVA laminated glass can be produced in convection (e.g. Lamijet Convection) or infrared lamination furnaces (e.g. Lamijet 04-2c); these furnaces are small and accessible to small and medium-sized enterprises. Processing with PVB film requires a special temperature-controlled chamber and the glass must then be processed in an autoclave, an expensive and large machine suitable for companies with large volumes.
  • Cross-linking rate > 94% (test result on STRATO® EXTRA CHIARO): EVA is thermally and mechanically stable, making it a material with a durability and stability well over any thermoplastic.
  • 3D Reticulation: can also reduce the number of layers in a tempered glass reaching a 50% reduction in manufacturing costs Vs an Autoclave.
  • Excellent compatibility with various insert media and easy lamination process with a wide variety of glass such as figured glass, tempered glass, curved glass, etc. as well as with inserted materials like fabrics, wood, perforated sheet metal and others
  • Good adhesion, strength, stability and physical properties to various kinds of substrates ranging from glass, metals to plastic films, etc.
  • Excellent durability against heat, moisture, UV, etc.
  • EVA is hydrophobic, has a three-dimensional cross-linked structure
  • It displays high long-term reliability also under severe conditions in outdoor uses
  • Easy handling, processing, high productivity and reliability
  • Good impact resistance over a wide temperature range /humidity /UV/ aging
  • Excellent durability and stable optical performance
  • Easy storage and handling
