Cavity wall ties may not be the first thought when you think of your home, but they play a crucial role in maintaining its structural integrity. These small metal components bridge the gap between the inner and outer walls of a cavity wall, ensuring stability while allowing the walls to move independently to accommodate temperature changes. However, not all wall ties are the same. Modern cavity wall ties and designs have developed and improved in comparison to older wall ties, offering durability, efficiency, and peace of mind.
In this blog, we’ll explore the evolution of cavity wall ties and why modern cavity wall ties used for replacement are an improved alternative.
What Are Cavity Wall Ties? A Quick Recap
Cavity wall ties are essentially connectors between the inner and outer leaves (or skins) of a cavity wall. Their primary functions include:
- Structural Support: They keep the two walls tied together, preventing bowing or collapse of the brickwork.
- Load Distribution: They help transfer loads across the two walls.
Historically, these ties were made from materials prone to deterioration, leading to significant issues over time.
The Problems with Older Cavity Wall Ties
Older cavity wall ties were commonly made of mild steel, which, and although these worked in the short term, they are prone to rusting over time. Once the mild steel is exposed to moisture and oxygen, it quickly led to rapid corrosion. Why is this an issue? Corroded ties expand as they rust, causing cracks in the mortar and potentially affecting the stability the wall. This is known as wall tie failure and is one of the most common reasons for structural issues in older buildings. These steel ties have a limited lifespan, often far shorter than the buildings they supported, why is why we are seeing failure happen more and more across homes in the UK.
Modern cavity wall ties are built with advanced materials and designs to combat these issues. Stainless steel wall ties are the new gold standard, offering benefits that mean you won’t need to worry about replacing them again.
Modern cavity wall ties are often made from stainless steel, a material renowned for its durability and resistance to rusting. Unlike mild steel, stainless steel is inherently rust-proof. This means we can ensure Longevity, reduced maintenance and long-term strength for maintaining the stability of your property.
Modern cavity wall ties demonstrate how even small upgrades in building materials can make a significant impact. By upgrading to stainless steel wall ties, builders and homeowners can ensure their properties remain structurally sound, energy-efficient, and expert from damp for decades to come.
