EN 1279 has been in the background of the glass trade since 1988, when discussions began with a view to agreement on a common European standard for sealed unit manufacture. The early 90’s saw the passing of the law; Construction Products Directive (CPD), that covered a large range of building materials. In essence it says if a common European Standard exists for any product then it is legally binding to use it. Executive Windows continue to improve the quality of their products by constantly achieving success in gaining accreditations such as EN1279 our sealed units are independently testing annually, achieving EN1279 status.
