First Class Windows

When it comes to windows, design is all-important. Whether you are looking for a period style such as traditional sash or Heritage Windows or perhaps something more modern like sleek aluminium windows or the latest UPVC windows, First Class Windows is the company to use. We take our time over crafting each window design as we want them to offer lasting style and performance and include energy-saving glass so that you can earn back your money on them. A wealth of attractive finishes and woodgrain effects (Golden Oak, Rosewood, and Mahogany) are available too.

White UPVC Windows

Extreme UPVC Windows

‘EXTREME’ perfectly encapsulates the brilliance of our UPVC windows and how they hugely outclass standard windows in security, style, and thermal efficiency.

Envisage Flush Windows

Envisage flush windows are our tribute to traditional flush casements and share many of the same hallmarks, only they better fulfil modern demands.

Aluminium Windows

Eclipse Aluminium Windows

An Eclipse Aluminium Windows is one of the slimmest window designs in existence, with its lean profile creating space for a large, glazed expanse.
