Underlays and Acoustic Underlays for Wood Flooring

Here at The Solid Wood Flooring Company we only recommend and supply the best underlays for your floor.  To highlight, wherever possible we recommend you glue your floor directly to your subfloor (see our guide Wood Flooring Adhesives).  However in some circumstances where you’ll need to ‘float’ the floor which is where these high quality underlays come in.  It is important to note that when floating a wood floor you should always glue the tongue and groove edges of the boards together using high quality D3 PVA glue such as our recommended Bona GluClic.

We offer three types of underlay to suit your needs; all of these products are manufactured to the highest standards by Interfloor from their Duralay range.

Vapourstop Sealing Strip

We also stock Interfloor’s Vapourstop Sealing Strips, these are used to cover the joints between the underlay to minimise any moisture effecting the back of your wood floor.

Please note, even foil backed underlays do not provide a ‘DPM’ (Damp Proof Membrane), prior to installing your floor you must always check the moisture content and humidity of the room to determine if you require an additional sealant or DPM.  For more information see our technical page: Damp Proof Membrane Sealants for Subfloors.
