What is EVA Interlayer?

EVA is a lucent interlayer made of ethylene-vinyl acetate which is placed in between two glass layers during the process of glass foliation, the production of laminated safety glass (LSG).

„ Design is not just what it looks like and feels like. Design is how it works“.

What is so Special About EVGUARD?

Recently, Wolfen EVGUARD is the first choice premium thermosetting interlayer available in the market for industrial glass manufacture and laminated polymers. Compared to competitive EVA products and cast resins EVGUARD is tridimensionally curable. The product does not contain any plasticizers and is heat-resisting afterwards its hardening. This means it can not be melted on by subsequent heat conduction.


What are the Unique EVGUARD Characteristics?

By the use of InsertTec products you may grant glass as your favorite building material any important effective long-term characteristic regarding design and safety:

  • Thanks to its excellent adherence and tridimensional curability EVGUARD is fully compatible with a wide range of glass inserts which grants a great scope for design in manifold shapes and colours.
  • EVGUARD may be stocked economically and easily shipped without consideration of any special requirement.
  • EVGUARD is applicable for manifold and simple processing in conventional ovens for lamination as well as per autoclaving.
  • EVGUARD performance tests according to strict European and American engineer standards guarantee excellent quality regarding solidity, temperature resistance, humidity resistance (also at naked kerbs), yellowing resistance toward UV radiation, durability (also of the inserts) as well as long-term resistance, even under extreme environmental impacts.
  • By reason of the high stability and resistance EVGUARD grants the bearing glass, it widely prevents breakage.
  • In the unlikely case of breakage EVGUARD reduces damages to persons or property by conglutination of the glass components with the EVA interlayer.
  • Owing to its thermal stability EVGUARD is of low flammability.
  • EVGUARD features premium optical and transparent qualities in consideration of light transmission.
  • EVGUARD filters off ultra violet radiation and thereby protects from UV light.
  • EVGUARD may serve as translucent glass blinds.
  • By reason of the sound-absorbing impact of the interlayer, EVGUARD is an efficient noise protection.
