Foilboard ® Tips

  • Using a longer snap blade will aid in ensuring the slit goes through the panel properly
  • Start with the areas that can use full sheets (saving time and unnecessary cutting)
  • Fit 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
