OUTDOOR APPLICATIONS

What are exterior end-use application of STRATO® EVA interlayers?

Laminated glass with STRATO® EVA is ideal for external applications. STRATO EVA interlayers—when properly laminated and installed—are certified to resist against humidity and water, UV radiation and any kind of weathering agent

Our EVA interlayers suit various outdoor end applications:

  • Curtain Wall
  • Storefront or commercial window
  • Street furniture and exterior structures
  • Windows

Meeting building codes and providing strength, sound reduction, solar control, visual beauty, and impact resistance for safety, security, and post-breakage performance are all attainable with laminated glass when using proper design. The multifunctional capabilities of STRATO interlayers can help meet changing guidelines and building safety codes.

In several years, laminated glass for impact resistance has demonstrated its protection capability. Now, thanks to STRATO interlayers, coupling that capability with sound control, color options, solar control enhancements, and security performance in a multifunctional glazing is not just easy to do—it’s a required option.

Why is the cross-linking important in the STRATO® EVA film?

Cross-linking is the general term for the process of forming covalent chemical bonds to join two polymer chains together. The term “curing” refers to the crosslinking of the thermosetting copolymer.

STRATO® EVA film is a thermosetting material: the lamination process activates the cross-linking of the molecules and as a consequence, the EVA film will not melt anymore when heated to high temperatures a second time after the curing because it is an irreversible process.

The cross-linking is carried out in order to improve the elongation, the rigidity, the aging and the heat resistance properties of the STRATO® EVA film.

The resulting characteristics of the crosslinked STRATO® EVA film are superior to the ones of a thermoplastic material such as PVB.

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

SAFETY GLASS

How to obtain the high transparency with safety?

With STRATO® CLEAR product range: it is increasingly in vogue to furnish by choosing transparency so as not to make the space heavier and to give elegance and refinement. Its high transparency also reflects the light creating pleasant effects and contrasts that make the whole thing brighter.

There are an infinite number of possible solutions in addition to the CLEAR product range: in fact, it is possible to choose other colors or finishes such as BIANCO, LATTE, NERO, SATINATO E LEGGERO and add fabric inserts, metal netting, colored films, etc..

With STRATO® you can create personalized furnishing elements without neglecting the aspect of safety.
