Koolfoam SlabEdge
Energy efficiency and sustainability now govern how homes are designed and built. But when it comes to slab floors, a significant amount of heat transfer can be through the slab's vertical edge.
To address this, changes to the H1 Energy Efficiency Building Code since May 2023 require edge insulation to be installed on all exterior exposed vertical faces of concrete slabs - from the top edge down to the bottom of the footing.
This innovative thermal edging solution has excellent compressive strength and thermal performance, is tough, durable and moisture resistant and ready to help you meet the H1 Building Code changes with your next build.
