  • A
    Low-E Insulation : General purpose Insulation with High reflectivity and low emissivity.
    Fire retardant : Thermal insulation performance is same with Low-E Insulation but fire safety is higher than G/P by adding fire resistant function which can delay spreading speed in fire.

    건축물 에너지 절약 설계 기준 6조1호 다목 2항 단열 규정 별표1(지역별 건축물 부위의 열관류율) 따라 (KS F 2277 열관류율 시험을 거친 로이단열재는 KOLAS인증 시험기관에서 발급받은 열관류율 시험성적서 제출하여 적합한 것으로 보며, KS L 9016열전도율 시험을 거치는 부피단열재는 별표3(등급별 단열재 두께) 따라 적합한 것으로 보고 있습니다.
    비교를 하자면 별표1 기준, 남부지역 공동주택 外 (열관류율 0.32 W/㎥K 이하인 경우) 로이단열재 40T(관련 단열성적서 제출) 사용 시, 비드법 2종 2호 100T [열관류율 0.32 W/㎥K (열전도율/두께=열관류율-> 0.032/0.1=0.32 W/㎥K)]와 두께 비교 가능합니다.
    즉, 남부지역 공동주택 외 로이단열재 40T를 사용할 경우 비드법 2종 2호는 100T를 사용해야 같은 성능을 볼 수 있습니다.

    Low-E Insulation is not suitable for KS L 9016 thermal conductivity test method.
    According to paragraph 5.2.1 of KS L 9016 Thermal Conductivity Measurement Method, "In principle, a test specimen is cut from a product or product, but if it cannot be cut, it is recommended to be manufactured under the same conditions as the product. However, the outer skin and other materials are removed."
    Low-E Insulation is a composite bulkhead insulation that combines aluminum and PE foam. If you remove the outer skin or other materials, it will not be a product, but it will only produce the thermal conductivity of each material.

    The thermal conductivity (flat thermometer method) is a unique characteristic of solid materials and is measured when the temperature difference of 1℃ is moved from high to low (1m distance, 1m2 area) to low temperature.
    The thermal perfusion rate (the insulation performance measurement method of building components - the training thermal box method and the protective thermal box method) is a measure of the building test structure measured when the temperature difference of 1℃ is moved from the anti-temperature side to the low-temperature side through the test structure.
    To see the insulation performance, you need to compare the heat perfusion rate.
  • A
    The report of the detached composition was recognized in the previous building energy saving design standards, but the current building law does not recognize the single report of insulation materials, but only the test report of the same wall composition as the construction site.
    (Refer to the energy saving design standards of the building, the thickness of the air layer shall be the same, but the rest of the materials shall be recognized even if the actual construction thickness increases.)

    Thermal perfusion rate test report validity period: No
    Semi-incombustible-conformity report validity period: within one year from the date of issuance of the relevant report
