    Quickstep Thermolevel 5mm Underlay is a laminate flooring underlay, which is suitable for domestic medium traffic areas. Ideal for laying new flooring on an uneven sub-floor, thanks to the self-levelling properties of the underlay.

    The Thermolevel underlay is the perfect choice for Quickstep laminate flooring, as it has been manufactured to complement the range in all situations. Thanks to the built-in damp proof membrane vapour barrier, this underlay can be laid upon concrete sub-floors and will fully protect your flooring from damp, moisture and mould - without the need for an extra DPM covering.

    Sound reduction properties ensure this underlay keeps footfall and impact noise to a minimum and the incredible thermal properties of this product ensure minimal heat is lost through your flooring.

    Please note, this underlay is also suitable for use with non-Quickstep laminate flooring products as well.

    How waterproof is this laminate for a utility area? Thx


    This flooring is fine for use in area where it may get wet, providing the flooring is sealed .We recommend a hydrokit sealant for the edges of the room where an expansion gap should be left, and also a click and seal, which can be applied to the edges of the boards when installed.
