Quanto Comprar

Área + 10% (reta) ou +15% (diagonal). O piso laminado é o revestimento mais acessível no Brasil: R$30-80/m². Classes: AC3 (quarto), AC4 (sala/cozinha), AC5 (comercial). Espessura mínima: 7 mm. Manta é obrigatória e melhora conforto e acústica.

Dicas

Não use laminado em banheiro ou área de serviço — a umidade destrói as juntas. Para áreas molhadas: vinílico LVT. Um DIY habilidoso instala 15-20 m²/dia.

⚡ 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.
