Cavity Brick Installation Guide

Simple step by step guide to installing Foilboard® GREEN rigid insulation


Step 1

Construct inner skin / face of brickwork including brick-ties as necessary and push the Foilboard® spacers over each tie.

Step 2

Press the Foilboard® GREEN rigid insulation panel firmly against the brick-ties so as to leave an impression. (with the GREEN anti-glare surface is facing outward)

Step 3

Make small cut through the Foilboard® GREEN rigid insulation panel where the brick-tie impressions have been made, using a sharp blade.

Step 4

Slide the Foilboard® GREEN panel over brick ties and tape all joins.

Step 5

Finish constructing the remaining external skin of brick work.

Foilboard ® Tips

  • Using a longer snap blade will aid in ensuring the slit goes through the panel properly
  • Start with areas that can use full sheets (saving time and unnecessary cutting)
  • Fill in remaining sections with smaller off-cuts, to help minimise waste
  • For measuring and cutting, use the Foilboard® gridlines as a guide
  • Use a foam or soft rubber roller over taped joins, to promote optimal adhesion
  • Foilboard® recommends also taping around the brick-ties to minimise air leakage
