  • TWINCARBO standard


    It is ultra-lightweight, about 1/5 the weight compared to a general polycarbonate sheet (same thickness), and the air space generated by the structure provides excellent heat insulation and heat conservation effect. As it has a SG processing (high weather coating), it also demonstrates high durability against yellowing and quality deterioration due to ultraviolet rays even outdoors. It can be selected from abundant color variations with 7 colors in total.

    TWINCARBO toughness

    TWINCARBO toughness 16mm

    TWINCARBO heat cut

    Pale green

    Breakthrough energy-saving product which provides an interior environment while cool in summer and warm in winter, by giving TWINCARBO a heat shielding function.

    TWINCARBO i series

    Fluorescent orange

    It emits beautiful light specific to fluorescent colors from a rib extending lengthwise and a cut section of TWINCARBO. It still increases brilliance with black light, etc.
