Insulation Fastening Applications with Pin & Washer

In insulation systems, performance is not solely determined by the material quality, but also by the application method. Pin and washer systems are crucial for securing insulation materials such as stone wool or elastomeric rubber, particularly in maritime and industrial settings.

What are Pins and Washers?

Pins and washers are fastening elements that consist of a metal or plastic pin and a wide-surfaced washer. Their primary functions are to:

- Secure insulation to surfaces

- Prevent sagging or loosening over time

- Enhance mechanical and thermal stability

Application Areas

Shipbuilding:

Structural insulation
Wall and ceiling panels
Exhaust system insulation

Industrial Plants:

Boiler rooms
HVAC ducting
Furnace insulation

How Are They Applied?

Clean the surface
Weld or glue the pin onto the metal sheet
Apply insulation material
Press the washer onto the pin
Bend or cap the pin for firm hold

Benefits:

Strong bonding
High temperature resistance
Quick and easy to install
Increases insulation durability
Protects from mechanical impact

Key Considerations:

Choose correct washer diameter
Don’t overuse pins — risk of thermal bridges
Match pin type to surface and insulation type
