    The best of both worlds

    It is possible to have the best of both worlds. SunGuard® SuperNeutral® products transmit high levels of light and reduce solar heat gain. While their neutral appearance is strikingly similar to clear, uncoated glass, they provide powerful thermal insulation by reflecting specific wavelengths of solar radiation. As a result, the sun’s heat stays out but natural daylight is welcomed in.

    By selectively transmitting natural sunlight, reflecting solar heat and insulating against fluctuating outdoor temperatures, SunGuard SuperNeutral architectural glass will reduce energy consumption and costs for heating, cooling and artificial lighting.

    Whether you are in a four-season climate or it’s hot year-round, SunGuard SuperNeutral glass offers just the right solar control and thermal insulation for the elements, all the while letting the maximum amount of light in. For warmer weather, it blocks heat and keeps cooled air inside. In colder weather, it blocks cold air and protects against heat loss. No matter the temperature, SuperNeutral controls the sun, insulates and provides great light for buildings.

    SunGuard® SuperNeutral (SN) 51/28 doesn’t sacrifice natural light to meet stringent solar control requirements. As a neutral, high selectivity glass option, SunGuard® SuperNeutral 51/28 offers advanced solar control and outstanding thermal insulation, while reducing the need for using artificial light. With a neutral transmitted and reflected colour, the product is ideal for full facade glazing. SunGuard® SuperNeutral 51/28 is available in heat-treatable and annealed forms, offering similar performances and appearance uniformity.
