Hardwood floor underlayment

Karelia Tuplex is a new generation underlay for hardwood flooring. Tuplex is made out of two layers of solid polythene with flexible polystyrene granules between the layers.

This structure makes Karelia Tuplex a clean, durable and lightweight material that is easy to handle and install, even in confined spaces. Tuplex also provides a highly effective double moisture barrier against subfloor humidity, obviating in most cases the need for a separate moisture barrier.

Levels out subfloor
Flexible construction helps smooth out any minor irregularities of the subfloor and provides an ideal base for hardwood flooring.

Ventilation
Tuplex's granular composition creates space between the floorboards and the subfloor, allowing for efficient ventilation.

Moisture barrier
The two-ply polyethene film of Tuplex makes it a highly effective double moisture barrier. In most cases there is no need for a separate moisture barrier. A test report is available form the manufacturer.

Sound insulation
Tuplex underlay combined with any commonly used intermediate floor construction meets the requirements pertaining to impact sound insulation in intermediate floors. Because of its high flexibility and resilience, its sound insulation properties will never wear out. A test report is available from the manufacturer.

Easy Installation
Laying the hardwood flooring is one of the final phases of interior decoration. At this point the room is usually full of recently finished surfaces which must be protected against dirt and dents. Karelia Tuplex is a clean, durable lightweight material that is easy to handle and install, even in confined spaces.
