Summary
The INSA P68 DA metal noise barrier is designed to provide double-sided sound absorption, effectively reducing noise on both sides of roads, transit routes, or high-traffic areas. Its special configuration also provides directional insulation, blocking sound transmission from one direction to the opposite
Compared to the P81 DA model, this version has a thinner profile, making it a lighter and more cost-effective solution for standard bidirectional acoustic control applications. Made of galvanized steel with a rock wool core, it combines excellent acoustic performance with high structural strength
Installation is normally done by embedding it into HEAA profiles, ensuring stability and durability. It is available painted in the RAL color range, with RAL 6009 (fir green) being the most common
Characteristics
- Maximum lightness.
- Variable module lengths.
- High acoustic absorption.
- Wide range of colors.
