Description
The Berlin Soundproof Window Program supports passive noise reduction measures in existing residential buildings in Berlin that were constructed before October 3, 1990. Owners, leasehold holders, and usufructuaries who are natural persons or legal entities under private law can apply for grants for the installation of soundproof windows, balcony and terrace doors, loggias, as well as ventilation systems. Also funded are the refurbishment of existing wooden box double windows and soundproof roller shutter boxes. The funding amount covers up to 90% of eligible costs, with a maximum of €15,000 per residential unit. For sound insulation class 4, up to €400 per square meter of installation area is granted, and for class 5, up to €500; for wooden box double windows, €500 per m² or a flat rate of €250 per room for ventilation systems. Compliance with technical specifications (VDI 2719, RAL guidelines), execution by authorized specialist companies, and proof according to DIN EN ISO 10140/717-1 are prerequisites. Noise pollution from federal highways or federal railways is excluded.
Funding applications can be submitted online at any time from January 1, 2024, to December 31, 2025, as long as budget funds are available. The application must include floor plans and elevation drawings, current land register excerpts, a De-minimis declaration, and at least three professional quotes.

Payment is made after submission of proof of use and completion of professional execution. This funding module complements active noise protection measures and contributes significantly to improving the quality of living on heavily trafficked main roads and above-ground BVG rail corridors.
