Why Use Stainless Steel Cavity Wall Ties?

Stainless steel cavity wall ties are designed for long-term performance in both domestic and commercial buildings. They resist rust and corrosion, making them ideal for areas exposed to moisture, sea air, or corrosive materials such as green oak. For tradesmen, this means fewer call-backs, reduced maintenance, and complete peace of mind that the job will last. Timco manufactures high-quality stainless steel cavity wall ties to meet the latest building standards, including Eurocode 5. Their tangle-free design makes them easy to handle on site, cutting down time and hassle.

Top Tips for Installing Wall Ties

1. Check the cavity width before choosing your tie. Each size and type has a specific range to ensure proper embedment.
2. Maintain at least 50 mm embedment in each leaf of masonry for a strong bond.
3. Follow spacing rules – typically 2.5 ties per m² (900 mm horizontal × 450 mm vertical). Around window or door openings, tighten spacing to 300 mm vertically and 225 mm from the opening edge.
4. Keep ties clean and level. Mortar on the surface can create a moisture bridge between leaves.
5. Always use stainless steel ties in coastal or damp conditions to prevent corrosion.

When to Use Screw-In Frame Ties

While Timco’s Type 2 and Type 4 ties are built into the mortar joints, the screw-in frame tie offers an alternative for remedial work or fixing inner and outer leaves where new masonry isn’t being laid. These screw-in versions are handy for renovations or extensions that join new and existing walls.
