Solar control glass

Light is beautiful, excessive heat is not

Solar control glass is tinted or coated glass that blocks heat and destructive UV rays while letting in visible light. Guardian scientists are constantly developing solar control solutions to serve a variety of needs: energy efficiency, design flexibility and occupant wellbeing. Whether a project needs to achieve LEED® credits or prevent hardwood floors from fading, Guardian can offer the right solar control solution.
