Polyester spunbonded fleece, reducing stress transferred to the sub-floor.

Bona U310 is a polyester spun bond fleece that reduces the stress transferred to the subfloor when laying prefabricated parquet, solid parquet and laminate on old parquet or other critical sub floors. Hairline-/shrinkage cracks in mineral sub floors can be bridged up to a width of 0.5 mm. Due to its high tear resistance the decoupling fleece reduces tensions from the sub floor and keeps them away from the subsequent top layer
