Thermal insulating glass for residential window upgrades

Guardian ClimaGuard^™ A+ is a thermal insulating glass developed for use in double and triple glazed insulating units, particularly in residential replacement windows. Designed to support compliance with current national and local building regulations in the UK and Ireland for existing dwellings, ClimaGuard A+ offers a balanced combination of thermal insulation and solar heat gain. Its tailored performance can contribute to achieving high Window Energy Ratings by allowing beneficial solar energy into the home, while helping to retain that heat indoors. This combination may support improved energy efficiency and comfort—particularly during colder months.
