What Are Type 4 Wall Ties 200mm?
200mm Type 4 (Light Duty) Wall Ties are manufactured from high-quality Austenitic Stainless Steel to securely connect the inner and outer leaves of cavity walls with a cavity width ranging from 50mm to 75mm.
Fully compliant with BS EN 845-1:2013+A1:2016 and supplied in a convenient box of 250, these ties are suitable for use in domestic houses and small commercial buildings up to defined height limits, offering excellent corrosion resistance and an effective double drip feature to prevent water transfer across the cavity.
What is a Type 4 Cavity Wall Tie?
A Type 4 Cavity Wall Tie, as defined by the European Standard BS EN 845-1, is a light-duty tie specifically designed for use in masonry cavity wall construction where the wind loading and building height fall within certain parameters. Its primary functions are:
- Structural Connection: To tie the inner and outer leaves of a cavity wall together, enabling them to act as a composite unit and resist lateral loads, primarily from wind pressure or suction.
- Accommodation of Movement: To allow for minor differential movement between the two leaves of masonry.
Characteristics
- Material: Manufactured from Austenitic Stainless Steel (typically Grade 1.4301 / AISI 304 or equivalent) for its excellent corrosion resistance and durability, crucial for components embedded within masonry for the lifetime of the building.
- Design: Incorporates a central double drip feature designed to be positioned in the centre of the clear cavity, preventing moisture from tracking from the outer leaf to the inner leaf.
- Application Scope: Type 4 ties are generally suitable for use in buildings with a maximum height of 15 metres as per BS EN 845-1, though typically used in domestic houses up to 10 metres tall in areas with wind speeds up to 25 m/s.
Always consult project-specific engineering advice and local building regulations.
Applications
- Connecting the inner and outer leaves of external cavity walls in new build domestic properties (detached, semi-detached, terraced houses, and bungalows).
- Suitable for small commercial buildings and extensions where height and wind loading are within the parameters for Type 4 ties (typically up to 10m height, verify against specific site conditions and engineering advice).
- Use with various masonry constructions, including brick-to-brick, brick-to-block, or block-to-block, where both leaves are generally 90mm thick or greater.
- Specifically for projects where the clear cavity width is between 50mm and 75mm.
Benefits
- Full Standards Compliance: Manufactured and tested in accordance with BS EN 845-1.
- Superior Corrosion Resistance: Made from Austenitic Stainless Steel, offering excellent long-term protection against rust and degradation.
- Effective Moisture Barrier: The precisely engineered central double drip feature prevents water from crossing the cavity, safeguarding the inner leaf from dampness.
- Ensures Structural Stability: Reliably connects the two leaves of a cavity wall, enhancing its ability to resist lateral wind loads and maintain structural integrity.
- Optimised for Common Cavities: The 200mm length is perfectly suited for 50mm to 75mm cavities, ensuring correct embedment and drip positioning.
- Light Duty Suitability: Specifically designed for typical domestic housing and small commercial structures within specified height limits.
- Ease of Installation: Standard wire tie design allows for straightforward embedment into mortar joints during bricklaying or blocklaying.
- Durable & Long-Lasting: Provides a lifespan consistent with that of the building when correctly installed.
