Marmox THERMOBLOCK® nano/53 is a patented insulating block, consisting of an insulating part with a thickness of 47 mm. The upper and lower sides are covered with a 3mm layer of (nano)polymeric cement, reinforced with a fibreglass mesh. The insulating part itself consists of extruded polystyrene foam (XPS) containing regularly spaced load-bearing (nano) polymeric concrete cylinders. These cylinders are inextricably connected to the upper and lower sides.

This unique structure gives Marmox THERMOBLOCK® a number of exceptional properties:

• R-value = 1 m2k/W
• Compressive strength = 10 N/mm²
• Watertight
• Lightweight
• Easy to work with
