Method of Calculating Quantities of Foilboard
- Calculate the area of the floor or wall.
- Increase the area by 5% to account for cutting and waste, and subtract the openings for windows and doors.
- If using 2.44m sheets, divide the area by 2.93 to determine the number of sheets needed.
- If using 2.70m sheets, divide the area by 3.24 to determine the number of sheets needed.
- Round up to the nearest whole sheet.
- Install floor saddles on joists approximately every 600mm and position them 200mm from the ends of the sheets.
- For retrofitting, use Foilboard to span across the underside of joists and between bearers, securing with three Foilboard fasteners per joist. Tape all joints, even if they’re not on a joist.
- Generally, plan for 1 bag of saddles per 45-50m2 and 1 roll of Green Tape per 100m2. For retrofitting, you’ll typically need 1 bag of Foilboard Fasteners and 1 roll of Green Tape for every 15-20 sheets. For Aluminium tape, estimate one roll per 10-12 sheets approximately. Use Flexifasteners for sheets 25mm or thicker, with 1 bag of 200 fasteners per 15-20 sheets. Alternatively, for sheets over 25mm, order plastic plates and provide your own fixing nails or screws.
- For brickwork spacers, allocate 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
