Abstract:
A method of providing solar control comprising:providing a flexible substrate having a first surface; and providing a damage-retardation layer at said first surface to protect a subsequently formed optical coating, said damage-retardation layer being a grey metal; providing said optical coating as a titanium nitride-based structure having a titanium nitride layer on a side of said damage-retardation layer opposite to said flexible substrate, thereby forming a coated flexible substrate; and attaching said coated flexible substrate to a rigid substrate through which solar control is sought; wherein a thickness of said titanium nitride layer is selected primarily for achieving desired optical characteristics and a thickness of said grey metal is selected primarily for achieving desired mechanical characteristics in retarding damage to said titanium nitride layer, and wherein providing said damage-retardation layer includes selecting a material to achieve desired characteristics with regard to low reflectivity and physical bonding to said titanium nitride layer.
