Introduction

EcoIn H120 black mineral wool is a high-temperature fire-seal insulating material exclusively designed for passive fire protection and fire blockage. This H120 black mineral wool is dark brown in color due to its iron-rich raw material composition, with its melting point exceeding 1150°C. As a premium fireproof material for curtain wall and structural fire protection, H120 black mineral wool offers superior resistance to shrinkage under high temperature compared to similar mineral wool products.

Easy cutting and convenient application

Application

ECOIN fire seal mineral wool board can effectively control the spread of flames and hot air currents by mean of fire resistance and blockage by the gap between curtain wall and structural floor or partition as well as ambient facilities such as chute that runs through floor or partition, thus forming fire barrier and dividing building into several areas to form passive fire blockage which remains effective for up to four hours at the most

applicable to thermal insulation and fire prevention of windowsill wall. As a passive fireproof structure of curtain wall, it can prevent the spread of flames from window to upper or adjacent units in case of fire through enhancing fire compartmentation effect of the wall between upper and lower windows.

It can be used for fire blocking of irregular gap.

H120 Black Mineral Wool – Frequently Asked Questions

H120 black mineral wool is a premium non-combustible fire-seal insulation from EcoIn with a melting point above 1000°C. According to Wikipedia, mineral wool is an inorganic fibrous material used globally for fire protection and thermal insulation in construction, marine, and industrial applications.

What is H120 black mineral wool and how does it differ from standard mineral wool?

H120 black mineral wool is a fire-seal grade, high-temperature mineral wool with a melting point exceeding 1150°C — significantly above the 700°C rating of standard mineral wool. EcoIn H120 black mineral wool is dark brown due to its iron-rich raw material. It meets ASTM E119, ISO 834, and BS 476 fire resistance standards with 1–4 hours of fire endurance. This makes H120 black mineral wool the preferred passive fire protection material for curtain wall cavity barriers, structural steel encasements, and marine bulkheads worldwide.

What density and thickness options are available for H120 black mineral wool?

EcoIn H120 black mineral wool is available in four nominal density grades: 60, 80, 110, and 128 kg/m³. Standard board size is 1200×600 mm. Thickness varies by density: 60 kg/m³ covers 100–150 mm; 80 and 110 kg/m³ cover 50–120 mm; 128 kg/m³ covers 50–100 mm. Custom sizes are available on request. These H120 black mineral wool options ensure suitability for a broad range of curtain wall, fireproofing, and industrial insulation projects globally.

Which fire and safety standards does H120 black mineral wool comply with?

EcoIn H120 black mineral wool complies with AS 1530.4-1997/ISO 834, ASTM E119/JIS A1304, and BS 476 Part 22, achieving 1–4 hours fire endurance. Smoke spread index is 5 and flame spread index is 0 per ASTM E84/UL 723. H120 black mineral wool is classified non-combustible (Reaction to fire Class A1) under EN ISO 1182 and EN 13501-1. Thermal conductivity is 0.036–0.039 W/mK at 20°C. These certifications confirm H120 black mineral wool meets the strictest global fire codes for high-risk construction and industrial applications.

What are the main applications of high temperature mineral wool?

H120 black mineral wool is installed as a fire seal and cavity barrier in curtain wall systems, preventing fire spread between floors. Additional applications include fire protection of structural steel, ship bulkhead and cabin insulation to IMO A60 standards, industrial furnace lining, and tunnel fireproofing. EcoIn supplies H120 black mineral wool to construction developers, shipbuilders, and petrochemical plant operators across 30+ countries, with custom-cut H120 black mineral wool boards available for any specification.
