Guardian's SunGuard High Selective Range Just Got Better!

Thanks to Guardian's continued work on coating deposition and measurement technology, it has been possible to further enhance the thermal insulation properties of its SunGuard High Selective (HS) coatings. This advancement has improved the HS range at a time when the demands from specifiers for lower and lower U values are becoming even more prominent.

Revisions in the Building Regulations have left a lot of older public buildings with deadlines to have their thermal efficiency improved. Rising costs and continually tightening financial budgets mean that meeting low SAP U value calculations is becoming more and more difficult. A good way to bring down the overall U value on old single skin walls that are lacking a thermal improving cavity, is to install exceptionally thermally insulated windows. In recent times, Guardian has seen requests for window U values as low as 0.7 and, further to that, centre pane U values as low as 0.47.

To achieve these strict performance requirements, it is necessary to have the best performing glass on the market and Guardian is pleased to say that Guardian SunGuard High Selective is one of the best performing glasses available. The perfect neutral appearance of SunGuard High Selective means that there is no need to compromise aesthetics for a strict performance of thermal insulation and solar control. The SunGuard High Selective range now has a normal emissivity of 1%. This can provide centre pane U values of 1.0 in a 6/16/4 Argon 90% IGU and even lower when used in triple glazing or with higher performing gases like Krypton or Zenon.
