Chain restaurants with drive-thru service rely on evening and late-night business, and that is precisely where the conflict with the neighborhood lies—intercom systems, engine noise from waiting vehicles, and slamming doors clash with reduced nighttime noise limits. Municipalities are increasingly linking operating hours to proven noise control measures. We install green, highly absorbent sound barriers along the order lane, menu board, and pick-up window, running alongside the drive-through lane and open to maintain visual connections wherever operations require them. The plants at the base of the walls trap fine particulate matter from waiting vehicles and require no watering. We provide planning, installation, and maintenance all under one roof from our location in Kaufbeuren—for individual locations as well as for franchise rollouts.
Deactivate the order lane and intercom system
Public address announcements on the menu board are among the sounds that residents notice at night, even at low volumes, because speech commands attention. A wall between the drive-thru lane and the residential area blocks the direct propagation of sound at the critical point on the property. Added to this are the idling noises of waiting vehicles, doors slamming in the parking lot, and the sound of orders being served—sources that accumulate over the course of the night. We route the wall along the traffic lane, keep sight triangles clear at the entrance and exit, and adjust the heights to match the location of the relevant neighboring windows. A green noise barrier blends into the landscape design rather than sealing off the site. The systems are typically filled with locally sourced soil and mineral raw materials, ensuring they remain dimensionally stable and durable. For franchise operators, we develop reusable design details so that subsequent locations can rely on proven solutions, and we also provide construction plans for coordination with local authorities and landlords. This creates a sound barrier that supports the restaurant’s operations rather than hindering them.
Ensure a Clean Appearance Over the Long Term
Locations along arterial roads struggle with vandalism, and large, bare walls attract graffiti when they appear as empty surfaces. Green wall systems structurally mitigate the problem, as vegetated surfaces offer graffiti artists virtually no usable surface; the system overview illustrates just how densely our green wall systems grow. The plants at the base of the wall are sustained by natural precipitation; there is no need to install or maintain an irrigation system—a compelling argument for retail locations with limited facility resources. On narrow lots, RAU Rock Extensiv, with a minimum width of 13 cm, creates the necessary space between the traffic lane and the property line. Chains that report on sustainability use the RAU Klimawand R3, whose Climate Handprint offsets emissions from raw materials, production, transportation, and construction within a few years through greening; the CO2 footprint has been verified by KlimAktiv. After opening, our service teams handle pruning and inspections upon request; the low-maintenance extensive construction method keeps the effort per location to a minimum. Installation is carried out entirely by our teams or provided as a kit for the chain’s framework agreement partner.
