ClimaGuard

ClimaGuard A+

Now with new performance figures – ClimaGuard A+ retains the same level of thermal insulation with an increased level of solar heat gain, offering the very best Window Energy Rating Results. ClimaGuard A+ is a Low E (Emissivity) glass, specifically designed to have a low 1.2 U value (W/m2K) combined with the highest level of solar heat gain possible with both a Clear (73% g value) or Low Iron (76% g value) glass outer pane. This balance means that the windows provide excellent thermal insulation whilst also allowing optimum solar heat gain to pass through the glazing and heat the interior of the building helping to reduce heating costs.
