Insulation Washers

(4 Products)

Insulation washers play a crucial role in insulation systems by providing a secure and efficient means of fixing insulation materials to various surfaces. These specialised washers help prevent thermal bridging, improve energy efficiency, and enhance the overall performance of insulation installations. We stock insulation clips (sold in a pack of 250) and insulation discs with a handy central hole for easy affixation.

What Are Insulation Washers? 

Insulation washers are small, disk-shaped components typically made of metal or plastic. They are designed to create a separation between the insulation material and the surface it is being installed on. 


This separation helps prevent thermal bridging, which occurs when a conductive material bypasses the insulation, compromising its effectiveness. Insulation washers are essential in maintaining the integrity and performance of insulation systems.

Types of Insulation Washers

There are various types of insulation washers available, including:

  • Metal Washers: These are typically made of corrosion-resistant metals like galvanized steel or stainless steel. They provide durability and strength for long-term insulation installations.
  • Plastic Washers: Made from high-density polyethylene (HDPE) or other durable plastics, plastic washers offer lightweight and non-corrosive options for insulation systems.
  • Fender Washers: Fender washers are larger in diameter than standard washers, providing a broader surface area for distributing the load and reducing the risk of compression damage to the insulation.

What Are The Benefits of Using Insulation Washers?

Insulation washers offer several key benefits, including:

  • Minimising thermal bridging: By creating a separation between the insulation and the surface, insulation washers help prevent thermal bridging, ensuring the insulation performs at its optimal level.
  • Enhancing energy efficiency: Insulation washers improve the energy efficiency of insulation systems by reducing heat transfer and improving overall insulation performance.
  • Preventing compressive damage: The use of washers, such as fender washers, helps distribute the load and prevent compression damage to the insulation, maintaining its effectiveness over time.
  • Providing long-lasting support: Insulation washers, especially those made of durable materials like metal or high-quality plastics, offer reliable and long-term support for insulation materials.
