Tunnel insulation hydrophobic rock wool board pit avoidance guide, be sure to avoid pits! The tunnel is a century old project, and once there is a problem with the rock wool board, replacing it is more than ten times more expensive than installing it. So during acceptance, not only is the thickness and flatness measured, but also the bonding strength pull-out test should be conducted. In the special environment of tunnels with high humidity, large temperature difference, and extremely strict fire prevention requirements, the selection of hydrophobic rock wool board is directly related to the quality and safety of the project.

Rosewool Insulation Refractory Co.,Ltd. has been committed to the research, development, production, and sales of thermal insulation materials for over 40 years, providing you with insulation material solutions for various industries. Below are some tips for selecting tunnel insulation rock wool boards to avoid pitfalls, which you can refer to;
                                                     

Guide for tunnel insulation hydrophobic rock wool board pit avoidance

1. Distinguishing between 'true hydrophobicity' and 'false hydrophobicity' - this is the biggest pitfall
2. Randomly selecting density - both strength and insulation suffer losses
3. Virtual thermal conductivity index - discounted insulation effect
4. Only looking at price, not qualifications - the most hidden pitfall
5. Fire protection level not up to standard - crossing the safety red line
6. Insufficient construction details - even good materials are useless


Guide to using hydrophobic rock wool board for tunnel insulation and pit avoidance? The above are the precautions for selecting hydrophobic rock wool boards that Rosewool Insulation Refractory Co.,Ltd. editors have compiled for you.

Boiler insulation material rock wool board selection manufacturer's pit avoidance guide

Boiler insulation material rock wool board selection manufacturer's pit avoidance guide? In boiler insulation engineering, rock wool board is a commonly used Class A non combustible insulation material. However, due to the mixed market, if the wrong manufacturer is selected, it is prone to problems such as cutting corners, insufficient density, poor hydrophobicity, and delayed supply, resulting in insulation failure, increased energy consumption, and even safety hazards.
