The Knauf Danoline Belgravia Unity 3 (U3) Ceiling Tile 600 × 600 × 12.5 mm is a premium perforated gypsum acoustic ceiling tile designed for modern commercial and institutional interiors. It features the distinctive Unity 3 (U3) square perforation pattern (3.5 × 3.5 mm holes), engineered to deliver effective sound absorption and acoustic comfort while maintaining a contemporary ceiling design.

Manufactured with a high-quality gypsum core and acoustic fleece backing, this ceiling tile provides excellent sound absorption (αw up to ~0.80–0.90), fire resistance (A2-s1, d0), and durability, making it suitable for demanding environments.

The tile is designed for installation in a recessed or semi-concealed T-grid system (T15/T24), offering a clean, elegant appearance with easy demountability for maintenance access. It also supports ventilation performance, allowing air to pass through the perforations for improved indoor comfort.

Suitable for offices, schools, hospitals, retail spaces, restaurants, and commercial buildings where acoustic performance, durability, and modern ceiling aesthetics are essential.
