Berechnung

Standardplatte: 250 × 125 cm (3,125 m²). Wandfläche = Umfang × Höhe - Türen/Fenster. Raum 4×3,5 bei 2,60 m: 39 - 4,2 = 34,8 m² ÷ 3,125 = 11,1 + 10% = 12 Platten. Knauf und Rigips (Saint-Gobain) sind die Marktführer in Deutschland.

Typen

Standard (GKB): normaler Einsatz. Feuchtraum (GKBI): Bad, Küche — grüne Kennzeichnung. Feuerschutz (GKF): Brandschutzanforderungen. In Bädern IMMER Feuchtraumplatten verwenden.

⚡ CalcWolf Insight

Using 4×12 sheets instead of 4×8 eliminates 33% of horizontal joints on standard 8-foot walls. Fewer joints means less taping, less compound, less sanding, and a smoother finished wall. The sheets are heavier and harder to handle but the finished result is noticeably better.
