Tuplex products are especially designed to fulfil the requirements of underlayment. They are created with careful product development to make perfect combination of characteristics such as acoustic properties, compression strength and levelling the subfloor. With Tuplex you can make sure that your floor lasts through the years in excellent shape.
Impact sound reduction
Tuplex products have excellent acoustic properties. They reduce impact sound and walking sound to the apartments below.
Excellent compressive strength
Tuplex holds in its shape under a load of 18 kPA – Extremely strong Tuplex LVT even up to 200 kPa!
Ideal with floor heating
Tuplex has a low thermal resistance that makes it ideal to use with a floor heating system.
Ventilation evaporates moisture
Special structure consisting of EPS beads and PE films generates ventilation that prevents mould formation under the floor.
Thin, safe and CE marked products
Polyethylene and polystyrene are stable and safe materials, generally used in food packaging industry. Emission class M1.
Levels the subfloor
Tuplex forms itself to the subfloor, eliminating slight variations and providing an even and firm support to the flooring.
