DIY Installation Tips

Bedarf

Fläche + 10% (gerade) oder +15% (diagonal). Laminat: 10-30 €/m². Nutzungsklassen: NK 23 (Schlafzimmer), NK 31 (Wohnzimmer), NK 32 (gewerblich). Mindestdicke: 7 mm. Trittschalldämmung ist Pflicht in Mietwohnungen.

Tipps

Kein Laminat im Bad — Feuchtigkeit zerstört die Verbindungen. Für Nassräume: Vinyl LVT. Ein geschickter Heimwerker verlegt 15-20 m²/Tag.

⚡ CalcWolf Insight

The biggest laminate installation mistake: not leaving expansion gaps. Laminate expands and contracts with humidity. Without a 1/4" gap at every wall, door frame, and fixed object, the floor will buckle. The gap is hidden by baseboards and transition strips.
