Guardian’s new single product solution for 1.0 U value performance - ClimaGuard A 1.0

Guardian’s ClimaGuard range is set to take a firm footing in the commercial market, with the launch of ClimaGuard A 1.0.

As a single stock Low E glass, ClimaGuard A 1.0 can be used either annealed or toughened and provides the optimum in thermal insulation, achieving a 1.0 U value in a standard 4/16/4 (90% Argon) IGU or U values as low as 0.4 W/m2K in triple glazed units.   

ClimaGuard A 1.0 is integral to the success of the Guardian ClimaGuard Low E glass range.  The New ClimaGuard A 1.0 provides some of the best thermal insulation on the market, combined with a high light transmission of 72% and a solar factor of 54%, making this ideal not only for commercial projects, but also for utilising solar heat gain in sustainable projects like those using the Passivhaus (Passive House) standard.

The solar factor of 54% offers mid level heat gains, which are ideal for carefully considered designs, where solar heat energy from the sun can be used to warm a building without risking overheating.   This also makes ClimaGuard A 1.0 ideal for triple glazing, where it easily helps to achieve the Passivhaus window requirement of 0.8 Uw and provides a manageable level of solar heat gain.  However, in exposed areas such as southern elevations or large areas of glazing, we would still recommend Guardian SunGuard where the right solar control and thermal insulation combination can be selected to meet the specific requirements of each individual project.

The New ClimaGuard A 1.0 has been developed by utilising the ClimaGuard A+ coating layer stack, which is well known for its stability and durability during processing and toughening.  Mark Bristow – Guardian Regional Manager for the UK & Ireland explained; “The technology used to create ClimaGuard A+ on our magnetron sputter coater at Goole is leading to a host of new product development’s, with ClimaGuard A 1.0 being the first to reach the market.  Having our own UK based coating facility has vastly improved our ability to produce products specifically tailored to suit the UK market, driving both innovation and energy saving”.
