Frequently Asked Questions

If your planks do not have pre-attached IXPE, yes. Underlay smooths minor subfloor imperfections, reduces footstep noise, and adds a vapor barrier over concrete. If your SPC already has attached pad, an extra layer is not needed - stacking underlays creates soft spots that stress the click joints.

1.5-2.0mm IXPE for SPC and LVT; 2-3mm EVA foam for laminate; 3-4mm natural cork where premium acoustics matter. Going thicker than recommended does not improve comfort - it increases joint stress and can void the flooring warranty.

Yes, but choose a thin, low thermal-resistance type: max 1.5-2mm IXPE or a dedicated heat-transfer underlay with an R-value below 0.15 m2K/W. Thick foam or rubber underlay insulates the floor and blocks heat from reaching the room.
