Guardian SunGuard™ High Durable coated glass in contact with SentryGlas® Xtra™ interlayers obtains a DTA for the French market


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. 

*Figure based on a reduction in the thickness of the base glass (Guardian ExtraClear™ glass) of 16mm (2x8mm) to 12mm (2x 6mm), interlayer and laminated glass process not included. The embodied carbon (calculated in the Guardian Glass Performance Calculator) for the 2x6mm base glass is 31.56 CO2 eq. kg/mA1-A3, approximately 27% lower compared to the 2x8mm base glass (43.52 CO2 eq. kg/m2 A1-A3). The embodied carbon data is the CO2 equivalent in kg per square meter of glass (CO2 eq.), emitted during the glass production (A1-A3, A1: raw materials supply, A2: transport, A3: manufacturing). The calculation is an estimation based on the material’s Embodied Carbon Factor (ECF) derived from the Regional EPD, third-party, independently verified document that communicates transparent information about the lifecycle environmental impacts of a product.
