2400mm Length Fireproof Rock Wool – Exterior Wall Insulation

Product Overview

Our 2400mm length fireproof rock wool is specially engineered for external wall insulation systems, breaking through traditional size limitations with an ultra-wide 2400mm format. Made from high-quality basalt through advanced melting, fiberizing, and curing processes, it offers Class A non-combustibility, excellent thermal insulation, and stable physical-chemical properties. The wide design significantly reduces panel joints, effectively blocking flame penetration paths, providing a safer fireproof insulation solution for high-rise buildings, curtain wall systems, steel structures, and large-span constructions.

Applications

Exterior insulation for high-rise and super-high-rise buildings
Curtain wall insulation and ventilated facade systems
Fireproof insulation for steel structures
Public buildings with strict fire safety requirements
Large-span exterior wall insulation projects

2400mm Length Fireproof Rock Wool– Exterior Wall Insulation

Key Features & Advantages

Class A Fire Safety - Minimizing Fire Risk

100% inorganic mineral fibers with a melting point above 1000°C: non-combustible, no toxic fumes, and no molten droplets—effectively blocks flame spread, maximizing protection for lives and property.

2400mm Wide Design - No Gaps for Flames

The ultra-wide format minimizes panel joints, eliminating potential flame penetration paths while enhancing overall facade fire performance and reducing thermal bridging.

Excellent Thermal Insulation

Dense fiber structure ensures low thermal conductivity and stable insulation performance, meeting building energy efficiency standards and supporting green building certifications.

Stable Physical-Chemical Properties

High acidity coefficient provides excellent resistance to corrosion, humidity, and chemical exposure—no powdering, no shrinkage, no collapse.
