Window Replacement Costs (2026)
When to Replace Windows

Custos no Brasil

Alumínio (o mais popular no Brasil): R$400-1.200 por janela instalada. PVC: R$600-1.500. Madeira: R$500-1.200. Vidro duplo (isolamento): adicione R$200-400 por janela. Uma casa com 10-15 janelas: R$4.000-15.000 em alumínio. No Brasil, janelas de alumínio dominam 70%+ do mercado residencial.

Vidro e Isolamento

Vidro simples para temperado: reduz ruído e melhora segurança. Vidro duplo: economia de 15-25% no AC em climas quentes. No Sul do Brasil, vidro duplo reduz tanto aquecimento quanto resfriamento — ROI de 5-8 anos.
