Title
(EN) SOLAR CONTROL SINGLE LOW-E SERIES WITH LOW VISIBLE REFLECTANCE
(FR) STRUCTURES SIMPLES DE VITRAGE SOLAIRE À FAIBLE ÉMISSIVITÉ AVEC FACTEUR DE RÉFLEXION RÉDUIT DANS LE VISIBLE
Abstract
(EN)
Low emissivity structures and methods are provided for reducing solar or visible transmissions with reduced reflectivity, such as for architectural glass. Reflectivity may be less than about 20% when visible transmissions are between about 20-70%. An absorption layer may be provided on one and/or both sides of the silver layer, such that absorption may be increased without excessively thickening other layers. In one embodiment, a low-E structure with reduced reflectance may comprise a glass substrate, a bottom dielectric, an absorption layer of a metal or metal nitride, a silver layer, a protective layer of a metal or metal nitride, and a top dielectric. The bottom absorption layer may have a thickness between about 5-75 angstroms.
(FR)
La présente invention concerne des structures à faible émissivité ainsi que des procédés destinés à réduire des émissions solaires ou visibles avec une réflectivité réduite, tel que pour du verre architectural. La réflectivité peut être inférieure à 20 % environ lorsque les émissions visibles sont entre environ 20 et 70 %. Une couche d'absorption peut être fournie sur un côté et/ou sur les deux côtés de la couche d'argent, de façon à augmenter l'absorption sans épaissir excessivement les autres couches. Dans un mode de réalisation, une structure à faible émissivité avec facteur de réflexion réduit peut comprendre un substrat de verre, un diélectrique inférieur, une couche d'absorption constituée de métal ou de nitrure de métal, une couche d'argent, une couche de protection constituée de métal ou de nitrure de métal, et un diélectrique supérieur. La couche d'absorption inférieure peut avoir une épaisseur d'environ 5 à 75 angströms.
