Should I install a separate or integrated damp screen underlay?

Scared that your floor might suffer damage from damp or moist rising from the screed? Here’s what you need to know about most-resistant underlays.

Damp screen underlay

Why a damp screen is necessary

If you have a concrete or screed underlay, or if you have underfloor heating installed, damp and moist can arise and possibly damage your floor or its Uniclic system. Even underlays that have been installed years ago can still emanate damp. In these cases, installing a damp screen is an absolute necessity.

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.
