SunGuard® High Performance - Silver 35/26


  • Curtain walling.
  • Window systems.
  • Spandrels.
  • Conservatory walls and roofs.


Produced on ExtraClear float glass, SunGuard® High Performance is manufactured by sputtering extremely thin, multiple layers of metal and metal oxides onto a glass substrate, based on the patented Silacoat® process. The dynamic performance of the various coatings on clear substrates covers the spectrum of energy-efficient, colourful design applications. SunGuard® High Performance glass delivers high visible light transmission and moderate reflectivity together with maximum energy savings that meet or exceed energy regulation requirements. The range can be further processed as follows:

Further processing:

  • Cut to size.
  • Toughening.
  • Heat soaking.
  • Heat strengthening.
  • Laminating.
  • Drilling.
  • Notching.
  • Bending.
  • Edgeworking.
  • CNC shaping.
  • Screen-printing.
  • Manufacture into suitable double or triple glass insulating units.


  • Smart: Spectrally selective; transmits visible light and reflects solar radiation for reduced solar heat gain.
  • Multifunctional: Solar control and thermal insulation in one coating designed to provide maximum flexibility. No need to use a Low E inner pane with this product.
  • Durable: Can be tempered and curved. Compatible with most glazing materials. Extended shelf life combined with short lead time. May be laminated or silk screen printed.
  • Valuable: Cost efficient in both winter (thermal insulation) and summer (solar heat rejection) for an outstanding continuous return on investment.
  • Helps to control the energy balance in buildings.
  • Controls glare from the sun.
  • Restricts solar gain, increasing the useable areas inside buildings.


  • Curtain walling.
  • Window systems.
  • Spandrels.
  • Conservatory walls and roofs.


Guardian Europe has ISO 9001 accreditation for the manufacture of float glass at all of its European based float glass plants. Guardian low-emissivity coated glass complies with the requirements of EN 1096-4: 'Glass in Building – Coated Glass'. Guardian also has ISO 14001 Environmental Management System standard.
