Noise Control Elements for Roads

Panels for horizontal or vertical applications

Design:
Highly absorbing
Aluminium, polyester powder-coated
Sound absorption DLα = 12 dB (A4)

The aluminium panels can be installed horizontally or vertically, with fixing material chosen accordingly. Substructures are used for attachment to compensate for an uneven underground or bored pile wall.

Standard dimensions:
Length: < 5.0 m
Height: 0.5 m

Highly absorbent noise barrier elements

Design:
Highly absorbing on one or both sides.
All types available in three sound insulation categories, also in a design that covers uprights.
Airborne sound insulation DLR = 25 – 31 dB (B3)
Sound absorption DLα = 8 – 12 dB (A3-A4)
Aluminium, polyester powder-coated
Installation: HE-160 till HE-240

Standard dimensions:
Length: 1.96 m, 2.46 m, 3.96 m and 4.96 m

Highly absorbent Delta top elements / Delta elements

Design: 
Highly absorbing on one or both sides, absorption zone tilted forward; generally designed to cover the uprights.
Airborne sound insulation DLR = 25 – 26 dB (B3)
Sound absorption DLα = 12 dB (A4)
Aluminium, polyester powder-coated
Installation: HEA160 and HEB160
