uPVC Casement Windows


The best selection of casement windows in the UK, supplied to your home within 2 weeks from the order date.

uPVC first became very popular in the 1980s when it began to be used as a replacement material for the mass of aluminium and steel windows that were previously installed across the UK. uPVC offered better value and an easier-to-maintain solution for homeowners.

Advances in manufacturing technology have seen the uPVC window evolve, and at Premier Windows, we can supply you with custom uPVC systems that offer the highest specifications and market-leading designs.

Our best seller is our flush casement window system, offering the highest levels of energy efficiency, security and comfort.

Our uPVC window system is #1 in Europe and the preferred system of architects, surveyors and government authorities. This is why:

  1. A-rated as standard, with an amazing U-Value of 1.2 – ensuring our uPVC windows are eco-friendly and lead free
  2. Thermal insulated, with noise-reduction panels that are exclusively designed in-house by us, dramatically reducing heat loss and external noise
  3. Our windows will not discolour, even in the most extreme of weather conditions
