Description
1. Product Overview
Rock wool strips offer excellent performance in thermal insulation, heat resistance, sound absorption, and fire protection. They are widely used in industrial equipment, building walls, curtain walls, and color steel sandwich panels, and are particularly suitable for insulation systems operating in high-temperature environments.
Due to their compact structure, high mechanical strength, and easy processing, rock wool strips are highly applicable and cost-effective in fire separation systems, building energy renovation projects, and industrial high-temperature insulation solutions.
2. Product Features
(1) Superior Thermal Insulation
With low thermal conductivity, rock wool strips effectively reduce energy loss and maintain stable performance under high temperatures.

8. Environmental Protection & Sustainability
Rock wool strips are made from natural raw materials with low energy consumption during production. Waste materials are recyclable, and the products themselves are non-toxic, harmless, biodegradable, and recyclable. They align with the development trends of green building materials. As an ideal alternative to traditional organic insulation, rock wool strips are widely used in green buildings and energy-saving renovation projects.
9. Case Studies
Case 1: South China Large-Scale Commercial Complex Facade System
High-density rock wool strips supplied by our company were used as fire barriers and curtain wall infill, covering a total area of 8,000㎡. The system significantly improved the building’s fire resistance rating and achieved Grade A in energy efficiency evaluation.

10. FAQ
Q1: What is the difference between rock wool strips and rock wool boards?
A1: Rock wool strips are typically narrow and elongated, making them ideal for fire barriers, curtain wall gap filling, and sealing complex structural joints. Rock wool boards, on the other hand, are designed for large-area applications such as wall and roof insulation.
