Rockwool Fire Safety Performance
Rockwool Panels Compliant with Fire Safety Standards (BS 476 Part 20 & 22: 1987)
SQUAREROCK™ panels were fire-tested by the Fire Safety Research Center, Faculty of Engineering, Chulalongkorn University, on both 100 mm and 50 mm walls.
Before Fire Test (a) 0:00 hr
SQUAREROCK™ Rockwool Panel Before Fire Test
SQUAREROCK™ panels have been tested under standardized fire resistance conditions using a certified furnace setup. The panels are installed as part of the test assembly, with sensors placed to monitor and measure heat transfer through the panel during exposure to fire. This testing method ensures accurate evaluation of the panel's fire resistance performance and its ability to limit heat transmission under fire conditions.
After Fire Test (p) 4:00 hr
SQUAREROCK™ Rockwool Panel After Fire Test
After fire exposure for the specified duration in accordance with BS 476, SQUAREROCK™ panels showed no significant structural damage. The panel integrity remained intact, maintaining its original form and structural strength. This demonstrates excellent fire resistance performance and structural stability under high-temperature conditions.
Test standard: BS 476 Part 20 & 22: 1987 — Fire Safety Research Center, Faculty of Engineering,
Chulalongkorn University. Full test reports are available on request at Email :
