FAQs

What are stainless steel housing ties used for?

Stainless steel housing ties are used to connect the inner and outer leaves of a cavity wall, providing structural stability and helping to maintain wall integrity under various load conditions.

Are these wall ties suitable for all building heights?

These ties are classified as Type 4, which means they’re suitable for houses and small buildings not exceeding 10 metres in height, typically in sheltered or moderate exposure areas.

Can these wall ties be used in coastal or exposed areas?

While they offer good corrosion resistance, for highly exposed or coastal environments, a heavier-duty wall tie (such as Type 2 or Type 3) may be more appropriate.

How many wall ties do I need per square metre?

The general recommendation is around 2.5 wall ties per square metre, but always check local building regulations and project-specific requirements.
