Method of Calculating Quantities of Foilboard

  • Measure Floor or Wall area.
  • Add 5% to area to allow for cutting and waste, deduct window and door openings.
  • If using 2.44m sheets divide the area by 2.93 to give the number of sheets required.
  • If using 2.70m sheets divide the area by 3.24 to give the number of sheets required.
  • Round up to the next full sheet.
  • Floor saddles should be on joists at approx 600mm centres and spaced at 200mm from sheet ends.
  • For retro-fits Foilboard should span across the underside of joists and between bearers using three Foilboard fasteners per joist. Joins do not need to be made on a joist and you should tape all joins.
  • Generally 1 bag of saddles is required for every 45-50m2 and 1 Role of Green Tape will be required for every 100m2. For retro-fits you will generally require 1 bag of Foilboard Fasteners and 1 roll of Green Tape for every 15-20 sheets, for Aluminium tape you will require one roll for every 10-12  sheets approx. Flexifastners should be used for all sheets 25mm or thicker and you will require 1 bag of 200 fastners for every 15-20 sheets. Or for sheets over 25mm in thickness you can order the plastic plates and supply your own fixing nails or screws. Spacers for brick work you will require 8-10 spacers per m2

Residential Wall

For example, an area of 130m2 (residential wall – timber/steel frame excluding windows) will require;

  • 45 sheets of Foilboard® Insulation Panel (2440mm x 1200mm, 2.93m2 per sheet)
  • 3 bags of fasteners (Standard or Ultra)
  • 3 Rolls of Green UV PVC Tape

Underfloor Area

For traditional underfloor applications using timber joists at 450mm centres (130m2);

  • 45 sheets of Foilboard® Insulation Panel (2440mm x 1200mm, 2.93m2 per sheet)
  • 3 bags of Foilboard® Floor Saddles
  • 3 Rolls of Green UV PVC Tape
