Want to learn how to insulate your slab from start to finish? ๐ท๐ก
In this guide, we walk you through a full slab installation using Kooltherm K3 underslab insulation and GreenGuard GG350 slab edge insulation - a powerful combination for meeting 7-Star energy standards and boosting home performance.
Kooltherm K3 delivers high thermal performance with minimal thickness, helping to reduce heat loss through the main body of the slab while improving indoor comfort year-round. While GreenGuard GG350 wraps the slab edge in a durable, high-density XPS barrier, reducing thermal bridging - one of the biggest sources of edge heat loss.
Youโll learn how to position and secure the boards for a clean, efficient finish thatโs ready for backfilling once the formwork comes off.
Together, these two systems create a complete thermal envelope around your slab, helping you achieve better energy efficiency, improved temperature stability, and compliance with todayโs higher performance requirements.
