An Insulating Glass Unit (IGU) is designed to reduce the amount of heat that passes through a window or doorset. When an IGU fails, it can mist up inside and destroy the appearance of the window.
Our IGU scheme is designed to verify that products are manufactured in line with EN 1279, to provide confidence that the product will perform as expected. Bluesky certification is a UKAS accredited certification body, No. 9413 and can provide accredited certification for the manufacture of IGUs to various standards; please look at our accreditation scope.
