Howdens supply a variety of flooring accessories for a professionally fitted floor. The right underlay is essential for use with floating floors. It provides thermal insulation and reduces the transmission of sound. A damp proof membrane can be used on screeded, stone or concrete sub floors before laying the underlay. Use flooring spacers around the edge of the floor to allow a gap for expansion and contraction, colour-matched scotias can then be used to cover the gaps left around the edge.
