Development of Heat Reflective Solar Control Coatings via Large‐Area Magnetron Sputtering to Architectural Glass Facade Applications

ABSTRACT The present manuscript discusses the advanced heat reflective sun control coatings produced by large area magnetron sputtering. To develop such sun control heat reflective coatings, we have used five different glass substrates, such as float clear, bronze, blue, green, and dark gray. The target materials, which we used for the sun control coatings, belong to the Groups IV A and VI B of the periodic table, that is, silicon nitride (Si ₃ N ₄ ), and chromium nitride (CrN). The deposition of such coatings on various glass substrates having a size of 2440 × 1220 mm was prepared and coated via large area magnetron sputtering under high vacuum conditions. The coated samples were analyzed by using various characterization techniques to evaluate their optical, thermal energy, mechanical, and morphology properties by UV–VIS–NIR spectrophotometer and field emission scanning electron microscopy (FESEM). The coated products have finally been found to be utilized for an application related to facade buildings toward sustainable solutions in the field of advanced engineering.
