UNDERLAYMENT

Information

PROPERTIES
Underlayment must be thick, flexible and adaptable to level up small irregularities of the surface. It should prevent formation of empty cavities that result in “drum sound” effect in a room. Density – 30 kg/m³. The underlayment conducts heat; therefore, it can be used for heat-insulated floors. Heat transfer coefficient – 0.041 W/mK. Floor underlayment should reduce noise as much as possible, i.e. sound reduction index should be .17 dB. Recovery after crushing - 30 percent. In addition, it is pressure-resistant, durable and does not lose its properties for more than 50 years.

INSTRUCTIONS FOR USE

Underlayment is used as an insulating layer between concrete or wooden floors and laminate flooring. The surface of the flooring must be dry and clean (free from nails, plaster, putty residue or other foreign objects). Before installing the underlayment on concrete or wooden surface, it is recommended to lay a polyethylene film and install the underlayment over the film. Polyethylene film reduces friction between the concrete or wooden floor surface and underlayment thus extending its service life.
Unroll the underlayment, and run it on the ground. Leaving a gap of 10–15 mm between the wall and the underlayment recommended; secure the seams with adhesive tape. Laminated flooring to be installed over the underlayment.
