Advantages

  • Hydrophobic treatment (0.75% paraffin) allows board to act as a temporary roof and weather and wind protection
  • Tongue and groove edges mean that boards’ edges do not have to line up with rafters in the roof
  • Raw material for all GUTEX insulation boards comes solely from wood that is harvested and grown using sustained forestry management practices
  • Boards are made using the dry process meaning that the boards contain 95.25% wood, and maximizes the use of this sustainable, recyclable natural resource
  • Can be installed directly over rafters without sheathing when shear / structural is achieved by other means
