NFRC 100 기준으로 Boundary Alumium, Improved, Broken 설정할 경우,
Thermal Break 길이에 따라 내부 바운더리를 세가지로 나누게 되는데
여기서 Thermal Break 은 실리콘 가스켓도 a low conductance material으로 볼 수 있나요?
Thermally Broken (TB) Members: system members with a minimum of 5.30 mm (0.210 in) separation provided by a low conductance material (where thermal conductivity ≤ 0.5 W/mK, (≤ 3.6 Btu·in/h·ft2·ºF) or open air space between the interior and exterior surfaces. Examples of such systems include (but are not limited to) pour and debridged urethane systems, crimped-in-place plastic isolator systems, and pressure glazed systems with intermittent fasteners.
