Description
80kg/m³ Curtain Wall Firestop Rock Wool Board – Flexible Fill · Joint Sealing
Product Overview

Our 80kg/m³ curtain wall firestop rock wool board is specially engineered for sealing joints and gaps in glass curtain wall systems. Designed with excellent compressibility and workability, it effectively fills gaps between curtain walls and floors, providing superior protection against flame and smoke spread.

Manufactured from high-quality rock wool with long, elastic fibers, this board conforms perfectly to irregular gaps and curtain wall framing components. It serves as an ideal firestopping solution for cost-sensitive projects requiring reliable performance.

Applications
  • Horizontal gap sealing between curtain wall floors
  • Firestop filling between window frames and walls
  • Sealing around curtain wall anchor penetrations
  • Fire wrapping for pipes through curtain walls
  • Projects with budget constraints

Key Features
Flexible Fill – Effective Fire Prevention

Excellent compressibility and resilience ensure tight filling of gaps between curtain walls and floors, comprehensively preventing flame and smoke spread.

Lightweight – Easy Installation

Lower density makes boards lighter for easier handling, cutting, and stuffing, accelerating installation processes.

Class A Fire Safety – Basic Protection

Rock wool is Class A non-combustible material with no burning, no flame, and no toxic smoke spread during fire events.

Weather-Resistant – Long-Term Effectiveness

High acidity coefficient ensures corrosion and aging resistance—no powdering, no shrinkage—maintaining seal performance over time.
