SF19 Multi-Foil Insulation
Ultra-Slim Insulation for Roof & Walls

SF19 is designed to insulate roofs, lofts, ceilings and walls inside or out. Ideal for new timber-frame construction or eco retrofit projects, SF19 provides maximum insulation in the minimum space.

  • 38mm foil quilt equivalent to 275mm wool or 140mm XPS board - based on comparative in-situ tests
  • Approved by building regs - 'R' value 2.218
  • 10 year guarantee with 50+ years life
  • Lightweight, flexible & easy to install - ideal for retrofit
  • Made from over 40% recycled materials

SuperFOIL is more resiliant to dust, drafts, pests and osmosys than mineral wool or extruded polystyrene, meaning it not only lasts longer, it maintains peak performance for longer too.

NOTE: For every roll of SF19 you install we suggest you allow 2-3 rolls of SF sticking tape, see related products opposite..
