How to Choosing the Right Cavity Wall Fixings

Cavity wall fixings, also known as cavity wall anchors or fasteners, are indispensable for securely attaching items to hollow walls. Yet, navigating the myriad options available can be overwhelming. Fear not! This guide is your compass, leading you through the labyrinth of cavity wall fixings to help you select the perfect fit for your project.

Understanding Cavity Wall Fixings


Cavity wall fixings are specially designed to provide a robust anchor point within the void space of cavity walls, ensuring stability and support for fixtures and fittings. They come in various types, each tailored to specific applications and load capacities.

Types of Cavity Wall Fixings

  1. Plastic Plugs: Simple yet effective, plastic plugs are suitable for lightweight to medium-duty applications. They expand when a screw is inserted, creating a secure grip within the wall cavity.
  2. Spring Toggle Anchors: Featuring spring-loaded wings, these anchors provide enhanced holding power, making them ideal for heavier loads. They are easy to install and offer reliable performance.
  3. Metal Cavity Anchors: Constructed from durable materials such as steel or zinc alloy, metal cavity anchors offer superior strength and load-bearing capacity. They are suitable for demanding applications and provide long-lasting reliability.

Factors to Consider When Choosing Cavity Wall Fixings

  1. Wall Construction: The type of cavity wall construction, including the materials used and the width of the cavity, will determine the appropriate fixing type and length. It’s essential to select fixings that can span the cavity and provide a secure grip on both wall layers.
  2. Load-Bearing Capacity: Consider the weight and load that the fixings will need to support. Heavier components, such as cladding or shelving units, will require stronger and more robust fixings to ensure safety and stability.
  3. Environmental Conditions: Exposure to moisture, temperature fluctuations, and other environmental factors can impact the performance and durability of cavity wall fixings. Choose fixings made from corrosion-resistant materials, such as stainless steel or high-quality plastics, to withstand harsh conditions.
  4. Thermal Performance: In energy-efficient buildings, cavity wall fixings can act as thermal bridges, allowing heat transfer between the outer and inner wall layers. Consider using fixings with thermal breaks or low thermal conductivity to maintain the insulation properties of the cavity wall.
  5. Installation Ease: Some cavity wall fixings are designed for easy installation, requiring minimal drilling or specialized tools. Consider the accessibility of the installation area and choose fixings that can be installed efficiently, reducing labor costs and project timelines.

Popular Cavity Wall Fixing Types

  1. Cavity Wall Ties: These are the most common type of cavity wall fixings, used to securely connect the outer and inner wall layers. They come in various materials, including stainless steel, galvanized steel, and plastic.
  2. Cavity Fire Barriers: These fixings are designed to prevent the spread of fire and smoke through the cavity, providing an essential safety feature in buildings.
  3. Cavity Tray Fixings: Used to secure cavity trays, which are designed to divert moisture away from the inner wall, these fixings ensure proper water management and prevent damp issues.
  4. Insulation Fixings: Specialized fixings are available for securing insulation materials within the cavity, ensuring optimal thermal performance and energy efficiency.
  5. Cladding Fixings: These fixings are designed to securely attach various types of cladding materials, such as brick slips, stone, or metal panels, to the outer wall layer.



When selecting cavity wall fixings, it’s essential to consult with professionals, such as architects, engineers, or experienced contractors, to ensure compliance with building codes and regulations. Additionally, follow the manufacturer’s instructions carefully for proper installation and load-bearing capacity guidelines.
