Elevate window performance without the pain of adding panes

Guardian ClimaGuard IS 20 interior surface coating can help dial up thermal insulation and solar control. IS 20 can help lower U-value when applied to the fourth surface of a double-pane insulated glass unit in combination with other ClimaGuard low-E coatings. To further amplify performance, apply ClimaGuard IS 20 to the sixth surface of a triple-glazed unit.
