Key Considerations for Cavity Wall Ties

Selecting cavity wall ties is important to ensure the structural stability and longevity of a building. Some key considerations when buying cavity wall ties include:

1. Material: Cavity wall ties are typically made of materials like stainless steel, galvanized steel, or plastic. The material should be chosen based on factors like durability, corrosion resistance, and compatibility with the construction materials.

2. Type: There are various types of cavity wall ties, including traditional wall ties, screw-in wall ties, and remedial wall ties. The type of wall tie required depends on factors like the type of wall construction, cavity width, and building regulations.

3. Length and Size: The length and size of the cavity wall ties should be selected based on the cavity width and the thickness of the walls being tied together. It is important to choose wall ties that provide sufficient embedment into the masonry to ensure structural stability.

4. Corrosion Resistance: In exterior or damp environments, it is important to choose cavity wall ties with adequate corrosion resistance to prevent rusting and degradation over time. Stainless steel wall ties are often recommended for their corrosion-resistant properties.

5. Compliance with Standards: Cavity wall ties should meet relevant industry standards and building regulations to ensure they are fit for purpose and provide the required level of structural support.

6. Thermal Performance: For buildings where thermal performance is important, consider cavity wall ties that minimize thermal bridging to help improve energy efficiency.

7. Manufacturer Reputation: When buying cavity wall ties, consider reputable manufacturers known for producing high-quality products. Researching reviews and testimonials can help assess the reputation of a manufacturer.

8. Installation: Consider how the cavity wall ties will be installed and whether any specialized tools or techniques are required. Proper installation is crucial for the effective performance of the wall ties.

By taking these considerations into account, you can select cavity wall ties that are suitable for your specific building construction needs and requirements.
