With a selectivity of 2.0, AGC’s new Stopray Vision‑70 solar control glass and its toughenable version Stopray Vision‑70T outperform all conventional double silver products.
These products are very colour neutral (Ra,D = 97), let in maximum daylight (TL = 70%), and, with a solar factor of just 35%, reduce the air conditioning requirements of buildings with all-glass facades. They deliver 15% internal light reflection, 14% external light reflection, and a low Ug value of 1.0 W (m2K) that keeps rooms warmer on cold days, which saves on heating costs and is good for the environment. These values are for double glazing, but the products are also available in triple-glazed insulating glass units. All standard glass products in the ipasol and Stopray family are Cradle to Cradle Certified Silver.
The Cradle to Cradle certification system evaluates the sustainability of a product across its entire life cycle. To achieve certification, a product must meet strict standards in five categories linked to health and the environment: Material Health, Material Reutilisation, Renewable Energy, Water Stewardship and Social Fairness.
The AGC Group is the only glassmaker to have earned Cradle to Cradle Certified status for its extensive portfolio of glass products – the largest in the world to be Bronze, Silver and Gold Certified. The overall score for Stopray, ipasol and iplus standard glass products is Silver. The products were rated Silver in the Renewable Energy and Water Stewardship categories, and Gold for Material Health, Material Reutilisation, and Social Fairness.
