The Overlooked Gap in Home Insulation

When it comes to insulating a home, many homeowners focus on base insulation, unaware that they could be leaving one of the biggest thermal gaps wide open. Slab edge insulation is often overlooked, but skipping it can lead to more than just a chill underfoot.

Without proper edge insulation, the perimeter of your concrete slab becomes a major channel for heat to escape. This doesn’t just affect comfort, it drives up energy bills and creates prime conditions for dampness and mould, especially around carpet edges.

Why It Matters

Without proper edge insulation, the perimeter of your concrete slab becomes a major thermal bridge, allowing heat to escape directly through the sides of the foundation. This not only reduces the overall energy efficiency of your home, but it can also lead to:

• Cold zones near floor edges

• Condensation and moisture buildup under carpets

• Increased risk of mould and dampness

• Long-term comfort and performance issues

In fact, studies have shown that up to 80% of heat lost through a concrete slab occurs at the edge, making this one of the most important areas to insulate properly.

A Smarter, Integrated Solution

To solve this, QuickSet offers a simple yet effective slab edge insulation system. It’s durable, easy to install, and designed to work seamlessly with common formwork systems. QuickSet and QuickEdge doesn’t just stop heat loss, it also helps reduce moisture ingress and supports a healthier, drier indoor environment.

For an even more efficient and fully integrated solution, Allied Concrete offers SuperSlab+, a high-performance insulated foundation system that includes:

• QuickEdge or QuickSet slab edge insulation

• QPOD void formers

• A streamlined design to meet and exceed H1 compliance under the New Zealand Building Code

Together, these components deliver a warm, energy-efficient, and structurally sound foundation, ideal for residential and light commercial builds.
