A high-transparency, low-emissivity film or coating (102) for a window (101) is designed to maximize so-called greenhouse heating. This effect is achieved through the use of conductive grids and/or gratings (102) whose width and spacing has been selected such that the grid (102) appears as a uniform conductive film to long wavelength infrared (blackbody) radiation (105). The conductive grid film (102) reflects the blackbody radiation (105) strongly, and such that the grid (102) appears highly transparent to visible and near-infrared light (104), and therefore transmits it.
La présente invention concerne un film ou revêtement de haute transparence et faible émissivité (102) pour une fenêtre (101) conçu pour maximiser ce que l'on appelle le chauffage à effet de serre. Cet effet est accompli par l'utilisation de grilles conductrices et/ou réseaux conducteurs (102) dont la largeur et l'espacement ont été choisis de telle sorte que la grille (102) apparaît comme un film conducteur uniforme au rayonnement infrarouge de longueur d'onde élevée (corps noir) (105). Le film de grille conductrice (102) réfléchit fortement le rayonnement de corps noir (105), et de telle sorte que la grille (102) apparaît hautement transparente à la lumière visible et proche infrarouge (104), et donc la transmet.
