Rock wool felt 50kg 25mm thick functional effect introduction:

 

1. Basic core insulation function

2. High temperature resistance suitable for metal boiler operating conditions

3. Fire and flame retardant safety function (essential for boiler core)

4. Sound insulation and noise reduction, improving the environment of the boiler room

5. Moisture and corrosion resistance, protecting metal boilers from rusting

6. Construction adaptation advantages (25mm thin 50kg rock wool exclusive)

7. Long lasting durability and reduced maintenance costs

 

Selection and usage precautions of insulation material rock wool felt:

 

1. Clear usage location

Confirm whether it is used on the boiler body or exhaust pipe. The surface temperature and usage requirements of different parts may vary, and products with different temperature resistance levels may need to be matched.

2. Reinforcement as needed

If used in areas with high vibration or requiring additional protection, it is recommended to consider using rock wool felt covered with iron wire mesh, which can effectively prevent tearing and detachment.

3. Check key indicators

When purchasing, pay attention to the thermal conductivity (lower is better) and thermal load shrinkage temperature (higher is more durable), which are key data to judge the insulation effect and temperature resistance.
