Linde Electronics and Specialty Gases manufactures and supplies rare gases, and rare gas mixtures to the worldwide window industry that incorporates these gases into windows and doors to increase their insulation value. Krypton, Xenon, Krypton/Argon, Krypton/Xenon gas mixtures are currently used as the insulating media in Insulated Glass Units (I.G.U.'s), low "E" Glass and windows that incorporate thin film technology to obtain increased "R" values. Linde also provides Krypton gas for sputtering of Low-E onto flat glass. Linde also provides Bulk Gases to the Window Industry such as Bulk Argon, Nitrogen, Oxygen, Hydrogen.
