Thermal insulation ISOROL

acousticEPSPET

Summary
The MAGNUM Isorol insulation roll is an expanded polystyrene (EPS) foam underlayment faced on one side with a 12 µm metallized PET film. It is designed as an underlayment for MAGNUM cable or mat systems (ensure adequate structural capacity for floating floors). The subfloor must be clean, free of dust and grease, smooth and dry. Irregularities greater than 2 mm per meter should be levelled. Lay the sheet with the PET face up and seal joints with aluminum/polyester tape (tape supplied separately).
