What are Insulating Mattresses? Structure, Benefits, and Industrial Applications

In factories using heating systems such as steam, heat transfer oil, hot water, or hot air, heat loss often occurs at locations such as valves, flanges, pumps, filters, or pipe bends.

These are often locations with complex shapes, making it difficult to install insulation using traditional materials. Therefore, many businesses choose to leave these locations open, leading to significant heat loss during operation.

To address this problem, removable insulating mattresses are chosen as a more flexible and effective insulation solution.

What is an Insulation Pad?

An insulation pad (also known as an insulation bag or removable insulation pad) is a thermal insulation product specifically designed for industrial equipment with unusual shapes.

Unlike traditional insulation which is usually fixed with sheet metal, insulation pads are custom-made to the actual dimensions of each piece of equipment and can be easily removed for inspection or maintenance.

This solution is commonly used for:

• Industrial valves
• Flanges
• Pumps
• Filters
• Pipe elbows/tees
• Heat exchangers
• Other complexly shaped thermal equipment

In Vietnam, Sodex Insulation is one of the leading manufacturers of custom-made insulation mattresses for specific equipment applications.

Structure of the Insulated Mattress

Covering Layer

Consists of an outer fabric layer and an inner fabric layer, which protect the inner insulation layer from dust, moisture, and environmental impacts during production, while also increasing the product’s durability.

Commonly used heat-resistant fabrics include:

• Silicone-coated fiberglass fabric
• PTFE fabric
• Silica fabric
• Other specialized heat-resistant fabrics

Insulation Core

This is the most important layer for minimizing heat loss.

Common materials include:

• Fiberglass
• Mineral wool
• Ceramic wool

Depending on the operating temperature and environment, Sodex Insulation will advise on the appropriate material to use.

Mechanism of Operation and Benefits

Insulating mattresses work by creating an insulating layer around hot equipment to limit heat transfer from the equipment to the outside environment.

This helps:

• Save energy: Minimize heat loss, thereby saving fuel and costs
• Ensure workplace safety: Lower the temperature of the production area, preventing burn risks for employees
• Optimize operation: Increase system efficiency and ensure equipment durability

Outstanding Advantages

• Flexibility: Quick and easy disassembly and assembly for inspection or maintenance.
• Reusability: Long lifespan, can be reused multiple times, superior to traditional insulation solutions.
• Precise Design: Manufactured individually to specific technical requirements.

Applications

Insulated mattresses are widely used in the following industries:

Any system with complex heating equipment can utilize this solution.

Specialized thermal insulation mattresses are particularly suitable when:

• Equipment requires frequent maintenance
• Complex valve systems are used
• Equipment has unusual shapes
• Energy cost optimization is desired
• CO₂ emission reduction targets are set

Conclusion

Insulated mattresses are a flexible and effective thermal insulation solution for complex equipment. With custom design and manufacturing services, Sodex Insulation helps businesses optimize thermal performance and achieve sustainable growth.
