What is Flat Roof Insulation?

Definition

Flat roof insulation improves energy efficiency in low-slope roof systems. Rigid boards are installed above or within roof layers.

Benefits

  • Energy Efficient: Reduces heat loss.
  • Versatile: Works with built-up felt, single-ply membranes, or green roofs.
  • Durable: Withstands compression and weathering.

Applications

  • ECO/MA, XtroLiner, FR/ALU, and FR/MG boards for flat roof insulation.
  • Suitable for new-builds and retrofits.

Best Practice Tips

  • Ensure continuous coverage to avoid thermal bridging.
  • Check compressive strength against roof loading.
