Guardian Glass and Kuraray have partnered to obtain a Document Technique d’Application (DTA) for the compatibility of Guardian SunGuard™ High Durable (HD) coatings (coating against interlayer) and SentryGlas® Xtra™ interlayer material. This combination offers architects and façade consultants a new opportunity to design a building envelope with high strength and energy performance.

Laminated Guardian SunGuard™ HD glass with SentryGlas® Xtra™ interlayer is particularly suitable for monolithic applications such as the outer envelope of double skin facades, canopies or atriums, as well as applications that require high resistance to mechanical and/or wind loads. The DTA validates all glass compositions where SentryGlas® Xtra™ is in direct contact with Guardian SunGuard™ HD coatings.

Combination of benefits
SentryGlas® Xtra™ is part of SentryGlas® ionoplast interlayers which are five times more tear resistant and up to 100 times stiffer than conventional PVB interlayers. Aside from its strength, SentryGlas® is much less susceptible to moisture exposure. Due to the structural properties of the interlayer, the use of SentryGlas® can also reduce overall glazing thickness, typically, by up to 30%. In addition, this reduction in glazing thickness can result in lowering the embodied carbon by approximately 27%*.

Guardian SunGuard™ HD coatings are made from highly resistant materials, which make them particularly suitable for monolithic applications. Guardian SunGuard™ HD solar control glass offers various aesthetics and external reflectivity, as well as different levels of light transmission and solar factor.

Matthieu Laude, Product Manager at Guardian Glass in Europe comments: “We are delighted to announce this product partnership with Kuraray which further positions our Guardian SunGuard™ HD solar control products as an ideal solution for monolithic applications. Laminated Guardian SunGuard HD glass with SentryGlas® Xtra™ interlayer offers several advantages for customers, not only from the combination of material properties. Having a readily available French DTA certification can save customers time and effort in applying for a certification specific to their project and can reduce the costs associated with this.”

Environmental stewardship and product certification
Both SentryGlas® and SunGuard™ HD products have Environmental Product Declarations (EPDs) available. FDES (Fiches de Déclaration Environmental et Sanitaire - Environmental and Health Declaration Sheets) are available for the Guardian coated glass. SunGuard™ HD products are bronze level v3.1 Cradle to Cradle certified®, as are all Guardian float glass, laminated glass and coated glass products manufactured in Europe.
