Effect of External Thermal Insulation Composite System with a Non-combustible Calcium Silicate Based Mineral on The Mitigation for Reducing Fast Spread of Flame

Abstract

As a building energy saving standard strengthened, The number of building installed external thermal insulation composite system(ETICS) using EPS insulation increased. But frequent fire accident in the buildings installed EIFS using EPS led to strengthening of building fire safety regulation. This study is for fire property of EPS ETICS reinforced with noncombustible calcium silicate-based mineral insulation as a fire spread prevention structure(FSPS). Fire test for large scale wall by ISO 13785-2 was applied and results showed EPS EIFS with FSPS got 3∼8 times superior fire safety than normal EIFS by visual investigation. Temperature and heat flux measurement results, which data of upside of specimen were lower than downside, also supported fire safety of EIFS with FSPS.

Properties of External Insulation Surface Preparation Mortar Using Expandable Graphite for Fire Resistance

“…Meanwhile, researchers have proposed various methods to improve the fire resistance performance of the thermal insulation layer in the event of a fire in the wet external thermal insulation [21,22]. In the wet application method of the external thermal insulation, however, the thickness of the finishing material and the surface preparation mortar on the outer part of the insulation is approximately 3 mm.…”
