  • Laminated Glass / Laminate / Laminating

    Two or more sheets of annealed or heat treated glass are separated by one or more plastic interlayers (normally PVB) and subjected to heat and pressure, in order to ensure perfect adhesion between constituent elements.

  • Light Reflectance (LRe)

    The proportion of the visible spectrum that is reflected by the glass.

  • Light Transmittance (LT)

    The proportion of the visible spectrum that is transmitted through the glass.

  • Low Iron

    Referring to extra clear glass, which has a reduced iron oxide content in order to lessen the green tinge inherent to ordinary clear float glass.

  • LSG Ratio

    Light to Solar Gain (LSG) is the ratio of the Visible Light Transmittance (VLT) and Solar Heat Gain Coefficient (SHGC) of a glass. In absolute percentage terms, a ratio greater than 1 signifies that the daylight passing through the glass is more than the sun’s direct heat passing through it.

  • Lacquered Glass

    Produced by depositing and baking lacquer coating on one side of clear glass.

  • Low Emissivity or low-E Glass

    Glass with a special thin-film metallic or oxide coating which allows the passage of short-wave solar energy into a building but prevents long-wave energy produced by heating systems and lighting from escaping outside.  Allows light to enter while also providing thermal insulation.
