The Co-Pro Alu-Line underlay is a slim underlay of approximately 3 mm thick, specially designed for laminate and parquet flooring. Thanks to the combination of lightweight PE foam and metallized foil, this underlay provides a comfortable, protective, and insulating base — without losing much build-up height.

Moisture-resistant and Insulating

The integrated aluminum foil acts as a moisture barrier, preventing rising damp from the subfloor. In addition, the underlay contributes to better thermal insulation and helps maintain a comfortable indoor climate.

Suitable for

• Laminate floors

• Parquet floors

• Rooms where build-up height is limited

Thanks to its low thickness, this underlay fits well in rooms where you don't want to create extra height, for example, under doors or near stair treads.

Easy to install

The underlay comes on a roll and is easy to process. For optimal performance, seal the seams with aluminum tape (not included as standard).

With the Co-Pro Alu-Line underlay, you choose a light, moisture-resistant, and sound-dampening base — perfect if you want a neat, level subfloor for your laminate or parquet, without much extra height.
