Bona U340 Polyester fibre board underlay 4mm (0.6sqm)

*SPECIAL ORDER*

Bona U340 is a polyester fibreboard underlay (4mm) that reduces the stress transferred to the sub-floor when installed prior to the final floor covering, such as ceramic tiles, natural stone and wood flooring.

Sold singularly, board size 0.6sqm

Description

Bona U340 is a polyester fibre board to be used as a stress relieving decoupling layer
below floor coverings such as parquet and other floor coverings. It can be used on
poorquality surfaces, like cracked or weak subfloors, or before the installation of solid
parquet types on dry screeds or particle boards. The high compressive strength
renders it capable of tolerating high loads (up to 5.0 kN/m²). It is suitable for use in
domestic and commercial premises. Additionally, the impact sound becomes reduced.
It is unaffected by damp and fungal decay. Due to its low heat transmission coefficient
Bona U340 may even be installed on warmwater floor heating.
