Description
2-Hour Fire-Resistant Curtain Wall Firestop Rock Wool Board – Floor-to-Floor Seal · Fire Compartmentation
Product Overview

Our 2-hour fire-resistant curtain wall firestop rock wool board is specially engineered for sealing gaps between glass curtain walls and floor slabs or solid walls. Certified by national fire testing authorities, it achieves a fire resistance rating of ≥2 hours.

Manufactured from high-density rock wool with a specialized formulation that expands when exposed to fire, this product effectively blocks flame and smoke penetration through curtain wall interlayer gaps, meeting stringent firestop application standards. It serves as a critical material for floor-to-floor fire compartmentation in high-rise buildings and commercial complexes.

Applications
  • Horizontal gap sealing between curtain walls and floor
  • Vertical gap sealing between curtain walls and solid walls
  • Fire compartment isolation between curtain wall floors
  • Firestop around refuge floors
  • Curtain wall projects requiring fire safety approval

Key Features
≥2 Hour Fire Resistance – Certified

Nationally tested for fire rating ≥2 hours, effectively preventing flame penetration through curtain wall gaps.

Dense Filling – Stop Fire Spread

The slight elasticity of rock wool can tightly fill the gaps and block radiant heat and smoke.

High Density – Compression Resistant

100kg/m³ density ensures good compressive strength, no settling or cracking over time, maintaining seal effectiveness.

Class A Non-Combustible

Rock wool is A-Class non-combustible, with no burning or toxic gas release during fire.

Easy Installation – Flexible Fit

Can be cut on-site to match gap dimensions, fitting tightly against curtain wall framing and floor edges.
