uPVC Window Styles Polhill

Modern Design

All of our available uPVC windows feature a modern design, even if solely based on technology.

Energy Efficiency

The two most important factors when looking for uPVC windows are style and thermal efficiency. If your new windows are not good insulators, your home will be cold and draughty. You will find yourself spending more money on central heating! Our uPVC windows are designed to help you save money spent on energy by keeping your home warm all year round.


Grey uPVC Windows Polhill

Highly Durable

Thanks to the nature of uPVC, these windows are designed to stand the test of time. With this, you can feel reassured that you are investing in a product that will add true value to your home for years to come. Completely weather resistant, your new windows will not warp or distort after exposure to wet weather. They are also designed to withstand great force.

uPVC Windows Styles Polhill

To ensure that we have something for everyone, we offer a wide variety of different uPVC window styles here at Thermaframe. Whether you are after something modern or country, we will have a selection of styles to choose from.

uPVC Casement Windows

Loved by many in Polhill, this style offers a versatile uPVC window solution. Casement windows have been around for decades, and when made using uPVC they can last even longer. Available in a range of colours and finishes these windows are the perfect base that can be built upon to create the window of your dreams.

uPVC French Casement Windows

If you are looking to add European flair to your Polhill property, uPVC French casement windows are a perfect choice. Opening in two parts like curtains, these windows work in the same way as French doors. Such a simple difference can add so much elegance.

uPVC Tilt and Turn Windows

Tilt and turn windows offer an extremely safe and secure design for all of our Polhill customers. Opening in two ways, by tilting inwards or outwards or completely open at the hinges, these doors are perfect for those at height or looking for a secure window. When your window is partially opened it cannot be forced fully open. Benefit for ventilation at all times.

uPVC Sliding Sash Windows

A stunning addition to any property, uPVC sash windows add elegance and graceful aesthetics. Previously made from timber, these uPVC windows offer style and functionality in all senses. Stand out from the crowd and add timeless allure to your property.

uPVC Flush Casement Windows

Also known as flush sash windows, these uPVC windows offer simple yet refined style for all homeowners. Similar to casement windows, these uPVC windows differ as the sash sits flush in the frame. This replicates traditional timber joinery.

uPVC Bow and Bay Windows

Add traditional grandeur to your property with our bow and bay style uPVC windows. Maximise lighting, add space and create a cosy window seat with this conventional window style. Made bespoke to meet your needs, these windows can be created to your very requirements.
