A method of making a window unit is provided which may result in improved yields. In certain example embodiments, the method involves coating a substrate with both (i) a solar control/management coating, and (ii) a protective layer (e.g., of or including diamond-like carbon (DLC) over the solar control/management coating. The protective layer protects the coated substrate from scratches and/or the like during processing prior to heat treatment. Then, during heat treatment, the protective layer(s) is burned off in part or in whole. Following heat treatment, the coated article (substrate with solar control/management coating thereon) is coupled to another substrate in order to form the window unit.
L'invention concerne un procédé de fabrication d'un bloc-fenêtre capable de fournir des rendements améliorés. Dans certains exemples de mise en oeuvre, ce procédé consiste à enduire un substrat (i) d'une couche de contrôle solaire et à appliquer (ii) une couche protectrice (p. ex. en carbone sous forme de diamant amorphe (CDA) ou contenant du CDA) par-dessus ladite couche de contrôle solaire. Cette couche protectrice protège le substrat enduit contre les rayures et/ou analogues lors d'un traitement préalable au traitement thermique. Ensuite, pendant le traitement thermique, la ou les couches protectrices sont en partie ou entièrement brûlées. Suite à ce traitement thermique, l'article enduit (substrat enduit de la couche de contrôle solaire) est relié à un autre substrat, de manière à former ledit bloc-fenêtre.
