Read full description

The JOKA JK124+ Alu-XPS-PRO AquaStop is a flexible underlay that provides optimal support for your floating click flooring. Thanks to its extruded polystyrene foam (HFPS) combined with an aluminium vapour barrier, this underlay effectively reduces impact sound and protects against rising moisture.

The underlay has a thickness of 2.2mm and is supplied in rolls of 12.5 metres by 120 centimetres, packaged per pack of 15 m². The material consists of extruded polystyrene foam with an aluminium vapour barrier layer, suitable for levelling out minor subfloor irregularities. Always check first whether your flooring already features an integrated underlay.

Benefits
✓ Effectively reduces impact sound beneath floating click floors
✓ Levels out minor subfloor irregularities
✓ Aluminium vapour barrier protects against rising moisture
✓ Flexible material for easy installation
✓ Convenient packaging of 15 m² per pack
