Polish Building Interior Design: Ventilation Standards and Wall Slat Trends

Poland’s building regulations require ventilation systems that meet the PN‑83/B‑03430 standard, covering residential and public structures. Proper ventilation—whether gravity‑based, mechanical or hybrid—protects occupants’ health, improves comfort and extends building lifespan. Regular maintenance, such as cleaning ducts and filters, is essential for system efficiency.

Wall slats are increasingly used in modern Polish interiors to add visual depth, define spaces and enhance acoustics. Available in materials like MDF and finished in colors ranging from light wood to white, they suit styles from minimalist to Scandinavian. Products are offered by companies such as Decor System, which provides easy‑to‑install slat systems for walls and partitions.
