According to attached Table 1 (KSF 2277 Thermal perfusion rate test) of Building Energy Saving Design Criteria No. 6-1 Multi-paragraph 2 Insulation Regulation (KSF 2277 Thermal perfusion rate test report issued by KOLAS certification test institution, volume insulation material according to KS L 9016 Thermal Performance test is reported.
For comparison, based on the attached Table 1, when using £ (submission of thermal perfusion rate of 0.32 W/m3K or less) Roidan Thermal Material 40T (submission of relevant insulation report), the bead method 2 No. 100T [Heat perfusion rate of 0.32 W/m3K] is comparable to 0.1/0.032= 0.32 W/m3K)]
In other words, apart from apartments in the southern part of the country, if you use 40T of heating materials, the bead method type 2 requires 100T to achieve the same performance.
