UPVC (Unplasticized Polyvinyl Chloride) has emerged as a top choice for modern window installations due to its durability, energy efficiency, and low maintenance. When comparing old windows vs UPVC windows, the advantages are significant. Unlike traditional wooden or aluminum windows, UPVC doesn’t warp, corrode, or need regular painting or sealing. Its long-lasting nature ensures protection, while offering a sleek, contemporary look that complements any home design.
