Advantages
- 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
