Advantages
- Raw material for all GUTEX insulation boards comes solely from wood that is harvested and grown using sustained forestry management practices
- Hydrophobic treatment (1.0% 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
- Boards are made using the dry process meaning that the boards contain 94.5% wood, and maximizes the use of this sustainable, recyclable natural resource
- Can be used in place of ULTRATHERM when protected by a Pro Clima roof underlayment such as SOLITEX MENTO 3000 Connect
- Can be installed directly over studs and rafters without sheathing when shear / structural is achieved by other means
