Abstract

An enclosure having a high efficiency solar control system is provided. The enclosure may have a transparent or opaque base layer and a film mounted to its exterior side. The film may reflect solar radiation in the near and mid infrared ranges yet allow high transmission of light in the visible range. The film may have a layer of silver which reflects the solar radiation in the near and mid infrared ranges. Since the silver is susceptible to oxidation and turns the silver into a black body which absorbs the near and mid infrared radiation, the film may be designed to slow the rate of oxidation of the silver layer to an acceptable level. The silver layer may be sandwiched between the base layer which may not allow oxygen to diffuse there through and reach the layer of silver and a stack of sacrificial layers having a certain thickness which slows down the rate of oxygen diffusion to an acceptable level.
