Integrate or separate: mind the thickness
To fully protect your floor, you can decide to install an underlay with an integrated damp-proof and moisture-resistant membrane. Since the underlay and damp screen are completely integrated, you’ll be able to save up to 50% of installation time.
If you opt for a separate damp screen – like the Quick-Step Screen underlay – you need to make sure it’s thick enough. Quick-Step advises to install a damp screen with the equivalent vapour barrier of an air layer with a thickness of at least 75 m (246 ft). That way your floor remains protected from any damp-related damage.
