Conservision glass is designed and manufactured by the world’s largest and most experienced glass insulator. Our glass is assembled using two separate seals, one on the spacer and one on the back side of the spacer. Because of the research and design of the Conservision glass we can prove that the chance of ever having a seal failure is one quarter of one percent after 20 years. As a matter of fact, in a laboratory comparison of seal failures, Conservision glass will outperform the next largest selling insulated glass by over 400%.
