Brand: TERMOLAN

Impact sound insulation under screed in high-performance cross-linked PE (dynamic stiffness s' = 46 MN/m³ , EN 29052-1). Roll 10×1.5 m = 15 m² , thickness 5 mm – quick continuous installation. Conductivity λD 0.034 W/mK , density 30 kg/m³ , compressibility < 1 mm . For floating floors, use as a professional acoustic insulation (perimeter strip + taped joints). Ideally, use with a traditional or self-leveling screed. Large quantities? The product is bulky (long package/pallet). For multiple orders (multiple rolls or entire pallets), contact us: we'll prepare a customized quote with shipping optimization and quantity discounts . This product may incur shipping surcharges.

How to lay it (quick guide)

Basic preparation : clean, level substrate. Lay a perimeter strip along all walls (avoid any hard contact between the screed and the walls).
Unroll REX XR with the edges butted. Tape the joints to ensure acoustic continuity and prevent sagging.
Separating film : where required by the specifications/screed, lay down a PE film (overlapping sheets ≥10 cm) to prevent the mixture from penetrating the insulation.
Pouring the screed (traditional or self-leveling): respect the minimum thicknesses and curing times. Advice : entrust this phase to a professional applicator.
Joints and details : take care of the passages of systems, thresholds and openings with clean cuts and taping to avoid acoustic bridges.em>.

Packaging & Logistics

Sales unit : single roll of 15 m² .
Approximate shipping size for a single roll: h ≈ 1.5 m; Ø ~ 28–33 cm (estimate); “long” neck.
For multiple orders, shipping on pallets with fixings and angle brackets is recommended.

Technical transparency : actual acoustic performance depends on screed, finish and installation details; the s' and λD parameters are the most correct for comparing materials.

FAQ — PAVITEMA REX XR 5 mm (impact sound insulation under screed)

What is PAVITEMA REX XR 5 mm and what is it used for?

PAVITEMA REX XR is a resilient anti-impact layer in cross-linked polyethylene to be laid under the screed to create a floating floor and reduce impact noise.

Can I use it without redoing the screed?

No. XR is designed for under screed . If you are not redoing the screed and are looking for insulation under laminate/parquet/LVT , use a dedicated acoustic underlay (not XR).

How many square meters does a roll cover?

Each roll measures 10×1.5 m → 15 m² . For cutsand scraps consider a +5–10% as a spare.

What acoustic performance should I expect?

The result It depends on the system (screed, finishing, installation details). The design parameter is thestrong>dynamic stiffness s' = 46 MN/m³rong> (EN 29052-1). The ΔLw reported in the literature varies depending on the package./p>

It is compatible with theem>underfloor heating?

Yes, in correct layered systems. Typically the resilient layer isstrong>under the screed And above any thermal panels. Always check with designer/massetener the stratigraphy and thicknesses.

What accessories are needed for a perfect installation?h3>

Perimeter band (cuts the acoustic bridges between the wall and the screed), joint tape (estate), and PE film as separator layer when required by the screed. Useful corner pieces/seals for utility passages.

Can it be used in bathrooms, kitchens, or wet areas?/h3>

Yes, with correct details:strong>lapel of the perimeter band, continuous film under screed and, if applicable, waterproofing above the screed before covering.
