Rock Wool Strip Dedicated for External Wall Insulation Fire‑Stop Belt
Product Overview
Taishi rock wool strip dedicated to fire stop belts for external wall thermal insulation is specially designed and manufactured to enhance the fire resistance performance of building external wall insulation systems. Matched with non Class A insulation materials for external walls, it functions as a fire stop belt to improve the overall fire safety of building facades. It features high compressive and tensile strength, low water absorption and moisture absorption, excellent dimensional stability, no thermal expansion or contraction, and good aging resistance.

Wide Applications
- Used as fire stop belts together with non Class A insulation materials such as EPS boards and XPS boards to improve fire safety performance of external wall insulation systems.
- Applied in thin plaster external wall insulation systems. Fibers are oriented perpendicular to the base wall surface to boost the tensile and compressive capacity of the system.
- Serves as the core material for metal sandwich composite panels for sites with high requirements for fire resistance, water proofing, thermal insulation and sound insulation.
Packaging & Storage
Rock wool strips are packed with pallets and plastic film, or bound by strapping for easy handling, transportation and storage. Products shall be stored indoors or covered with waterproof materials.
