Why Wall Cavities Matter?

A well-designed wall cavity is more than just a gap between two walls - it's a critical component of a durable, energy-efficient building.

Wall cavities help prevent moisture from penetrating internal walls by allowing any water that enters the outer leaf to drain away. They also improve thermal performance by reducing heat transfer, helping to keep buildings cooler in summer and warmer in winter. Properly constructed cavities can reduce the risk of damp, mould growth and long-term structural deterioration caused by trapped moisture.

At Coastline Developments, we understand that quality construction starts with the details. Every element, including the wall cavity, plays an important role in ensuring a stronger, longer-lasting home or building.
