Underlay for floating floors has support of dampproof paper or plastics film bonded or coated right over and overlapping at edges onto adjoining underlay strip.

摘要

The support material (3) extends right over the underlay underside and has one integral support part (4) extending beyond one underlay (1) edge to support the edge of the adjoining underlay strip. The support material (3) is coated onto or bonded to the underside of the underlay and should be incompressible. The extended part (4) runs as a strip along the edge of the underlay and can possibly be bonded to the underneath surface of the adjoining underlay strip (6), this adjoining strip being coated with a self-adhering band or activated glue layer.
