이에 따라 관련업계에서는 다양한 방법으로 연구를 진행하고 있으나, 대부분이 난연3급(난연) 수준에 머물러 있으며, 외단열용에 최적화된 난연2급(준불연) 수준의 단열재 개발이 시급하다, 또한 단열재를 고정설치하기 위한 철물이 없어도 설치가 용이하며, 단열성능, 구조성능을 향상시킬 수 있는 건식 외단열 시공방법의 개발이 필요한 실정이다.Accordingly, the related industry has been conducting research in various ways, but most of them are staying at the level of flame retardant grade 3 (flame retardant), and it is urgent to develop a flame retardant grade 2 (semi-flammable) insulation material optimized for external heat insulation. It is necessary to develop a dry external insulation construction method capable of improving the heat insulation performance and structural performance.

위의 표 2를 통해 알 수 있듯이, 가열시험 개시 후 5분간 총 방출열량의 경우 실시예 1은 6.7MJ/㎡, 실시예 2는 8.2MJ/㎡, 실시예 3은 8.4MJ/㎡, 실시예 4는 8.3 MJ/㎡, 실시예 5는 7.7MJ/㎡로 나타났다.As can be seen from the above Table 2, the total heat release amount for 5 minutes after the start of the heating test was 6.7 MJ / m 2 for Example 1, 8.2 MJ / m 2 for Example 2, 8.4 MJ / m 2 for Example 3, 4 was 8.3 MJ / m 2, and Example 5 was 7.7 MJ / m 2.
