Moisture resistant wood fiberboard insulation and weather resistive barrier in one, for exterior walls under rain screens. Can also be used as pitched roof insulation when protected with a Pro Clima membrane.


  • Raw material for all GUTEX insulation boards comes solely from wood that is harvested and grown using sustainable forestry management practices
  • Hydrophobic treatment (1.0% paraffin) allows boards to act as temporary weather and wind protection
  • Tongue and groove edges mean that boards edges do not have to line up with rafters in the roof
  • Boards are made using the dry process meaning that the boards contain 95% wood, and maximizes the use of this sustainable, recyclable natural resource
  • Can be used above sheathing when protected by a ProClima roofing underlayment such as SOLITEX MENTO 3000 Connect or SOLITEX MENTO PLUS
  • Can be installed directly over studs and rafters without sheathing when shear / structural is achieved by other means
