Extreme UPVC windows are highly regarded by homeowners in South Wales and a popular replacement design for traditional wooden window frames. The benefits of an Extreme window are incredibly extensive and diverse, and you couldn’t wish for a more reliable substitute for your existing window designs. Their biggest strength is ironically, their strength, so they can combat the indifferent weather that South Wales is so often subjected to.

Extreme UPVC Windows

Rotting, rusting, fading etc., doesn’t afflict Extreme UPVC windows and they’re so low maintenance that repainting isn’t necessary. When the window frame gets dirty, all you need is a soft cloth and warm water to wipe it clean.

Extreme windows have a dedicated colour palette, with a varied choice of attractive finishes, and they can be provided in almost any window style.

A+ energy rated windows come as standard...

Did you know that your old windows could be responsible for around 25% of the heat lost from your property? Any EXTREME windows bought from First Class Windows carry an A+ energy rated as standard. This exceeds the thermal qualities of most replacement windows in the region. Our A+ energy rated windows are also great for solar control and will keep the internal temperature just right.

Personalise your UPVC windows

Selecting a window style is just the very beginning of the buying process. From there, you need to choose a coloured finish, some hardware, and a form of glass.

Decorative glass styles with privacy at their heart…

Glass is one of the most fundamental elements of any window design and must not be underestimated. Without a reliable glass pane, a window will struggle to perform to the level that it should. All the glazing options we have at First Class Windows promise a captivating view and can be discussed individually with one of our knowledgeable advisors who really know their stuff.

Intricately crafted handles…

You simply must come along to our showroom and touch the many versions of traditional and modern-styled handles that we have. Only by feeling them can you appreciate the skill involved in crafting them.

As it engages, the locking system inside our handles has a big role in keeping them so secure.
