Frequently asked questions

  • What is uPVC?

    uPVC is a popular material for windows as an alternative to painted timber. It's tough, low-cost, low-maintenance, weatherproof and lightweight. uPVC stands for "unplasticised polyvinyl chloride".

  • When should uPVC windows be replaced?

    uPVC windows usually last around 20 years – high-quality windows can last up to 35 years. All our uPVC windows come with a 10-year warranty.*

  • Are uPVC windows soundproof?

    uPVC windows are well-sealed, meaning they are great at keeping out sound. Double or triple glazing is a good option if you want to keep the noise out, as well as the heat in.
