Q: What insulation can be used in the Durapanel Exterior Wall batten space?

Any 70mm insulation product, but we recommend 70mm Mammoth which is moisture resistant & give R2.3 finish wall value. Recommended product – 75mm Mammoth Semi Rigid Polyester Insulation R2.0 Expol, XPS, PIR or similar products may be used but consideration must be given to electrical cable insulation compatibility.
