Information
Polyester fibre board underlay that reduces the stress transferred to the sub-floor.
Bona U340 is a polyester fibreboard underlay that reduces stress transferred to the sub-floor when installed prior to the final floor covering, such as ceramic tiles, natural stone and wood flooring. The high compressive strength allows it to tolerate high loads (of up to 5.0 kN/m²). It is suitable for use in both domestic and commercial premises.
