Excellence Endurance is a physically crosslinked closed-cell polyolefine (PO)- foam faced with an
aluminised foil to further improve water vapour resistance, aspect and gliding performance.
It has been specially developed for laminate and parquet underlay.
Excellence Endurance provides an excellent reflected walking sound performance (low sound
reflection) and good impact sound reduction (low sound transmission).
Excellence Endurance is highly elastical and keeps almost its initial thickness and excellent
properties even after being exposed to extreme statical and cyclic loadings.
Dimensions:
20000 L x 1000 W x 2 TH
Packaging:
per roll – 20m² (48 kg net)
Per pallet 15 rolls – 300 m² (720 kg net)
Composition:
Excellence Endurance is a physically crosslinked closed-cell polyolefine (PO)- foam faced with an
aluminised foil to further improve water vapour resistance, aspect and gliding performance.
Installation Instruction: The underlay is laid and tailored perpendicular to the laying direction of the coverage.
Make sure the edges are flush against each other.
Only for floating installation. Obtain clearance of the floor manufacturers.
Especially important for SRL with vapour barrier foil to establish the vapour barrier.
