Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of smoke exhaust rock wool, it is recommended to prioritize checking key technical parameters such as fire resistance limit, density, and thermal conductivity of the product to ensure compliance with the design requirements of building fire protection systems.
  • In the application of smoke exhaust systems in commercial complexes or industrial plants, the thickness and bulk density of smoke exhaust rock wool need to be matched according to the actual needs of pipeline structure and fire zones to avoid performance redundancy or insufficiency.
  • When selecting suppliers, priority should be given to product matching, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to balance procurement risks and efficiency.
  • For special scenarios such as subway tunnels, attention should be paid to the hydrophobicity and compressive strength indicators of smoke exhaust rock wool. Such environments usually require higher durability of materials than conventional buildings.

Knowledge Base

Q

When choosing smoke control materials, rock wool is usually more suitable because it has a higher fire resistance limit and better fire resistance performance. However, glass wool has more advantages in terms of insulation performance and cost. From the perspective of fire resistance, rock wool has better fire resistance than glass wool. The maximum high temperature resistance of rock wool can reach 1000, while the high temperature resistance of glass wool is about 538.

Q

In smoke control systems, the commonly used rock wool insulation material is the smoke control rock wool board, which is specifically designed for such systems. This material is made from natural rocks such as basalt through high-temperature melting and special processes, integrating multiple properties such as fire prevention, heat insulation, and sound absorption. It has excellent fire resistance and belongs to Class A non combustible materials, which can effectively block fire. Excellent insulation effect,

Q

The lifespan of smoke exhaust rock wool is affected by various factors, mainly including environmental conditions, physical damage, etc. Under ideal conditions: when dry, with minimal temperature and humidity changes, unaffected by external forces, and with good installation quality, the service life of smoke exhaust rock wool can be comparable to that of buildings, reaching over 50 years. This is because the chemical properties of rock wool are relatively stable.
