REGUPOL sound 47
UNDERLAY, IN PANELS OR ROLLS, FOR IMPACT SOUND INSULATION
REGUPOL sound 47 is an 8 mm (5/16 in) underlay in rolls of PUR-bonded rubber fibres for impact sound insulation under floating screeds. Compact and stable (compressibility c ≤ 1 mm (≤ 0.039 in)), it keeps the build-up thin while giving ΔLw ≥ 22 dB.
Long rolls of 13 × 1.15 m (43 × 3.8 ft) cover large areas quickly, with live loads up to 30 kN/m² (4.4 psi).
NOTE
- Material: polyurethane-bonded rubber fibres, dimpled profile on the underside.
- Format: rolls 13000 × 1150 mm (512 × 45 1/4 in), 8 mm (5/16 in); weight 3.6 kg/m² (0.74 lb/ft²).
- Dynamic stiffness s't 30 MN/m³ (111 lbf/in³).
- Impact sound reduction ΔLw ≥ 22 dB.
- Maximum live load 30 kN/m² (4.4 psi).
- European Technical Assessment ETA-10/0056.
- Compressibility c ≤ 1 mm (≤ 0.039 in) (DIN EN 12431).
PACKAGING
- Impact sound insulation under floating screeds where thickness is limited.
- Residential and commercial buildings.
