Things

PAVITEMA REX WR Duo is a resilient impact sound insulation layer for floating floors: a quality cross-linked polyethylene coupled with polyester fibre acoustic felt to obtain low dynamic stiffness ( s' ≈ 12 MN/m³ ).

When to choose it

If you want more performance than 5mm single ply.
In renovations where you must comply with the limits of the Prime Ministerial Decree of 5/12/97 on impact noise.
For condominiums and units with lightweight floors, where a “softer” and thicker insulation is required.

Format & main data

Thickness	10 mm (5+5)
Roll dimensions	10,000 × 1,500 mm → 1 5 m²
Dynamic stiffness	12 MN/m³ (EN 29052-1)
λD	0.037 W/mK
Compressibility	2.52 mm (EN 12431)
Nominal density	approximately 35 kg/m³
Impact performance (note)	Indicated ΔLw 32–34 dB depending on references; depends on the screed and finishing package .

How to pose (guided for theadvanced DIY)

Clean and level base . Apply perimeter striping to all walls/pillars.
Unroll WR Duo with sheets placed side by side ( head to head ) and tape the joints for continuity.
Separating layer (if required by the screed): PE film with 10–20 cm overlaps and turn-up.
Traditional/self-leveling screed casting : respects minimum thicknesses and curing.
Critical details : system passages and thresholds must be sealed to avoid acoustic bridges .

Packaging & Logistics

Sales unit : 75 m² roll.
Approximate weight (density 35 kg/m³): ~ 26 kg per roll. Long and bulky package; pallets are often convenient for larger quantities.

Technical transparency : Final acoustic performance depends on the screed, finish, and proper execution of details. The s' and ΔLw parameters vary depending on the system. See the attached technical data sheet.

FAQ — PAVITEMA REX WR Duo 10 mm

What is WR Duo and why “5+5”?

It is an impact sound insulation made of cross-linked PE coupled with felt . The total thickness is 10 mm (two layers).5 mm coupled), to reduce the dynamic stiffness/strong> and vibrations.

Is it better than the 5mm single layer?/h3>

For “critical” impacts and floors, yes: theng>s' ≈ 12 MN/m³ong> It is lower than a standard 5 mm, so it absorbs foot traffic better.p>

Compatible with underfloor heating?

Yes in correct systems. Typically the resilient layer isstrong>under the screed And above Any system panels. Check the stratigraphy and thicknesses with the screed layer.
