Our Windows Collection

uPVC casement windows provide comfort and security, are long lasting and virtually maintenance free. All of our casement windows are double glazed and sealed to provide superior insulation, helping to save you money on your gas and electricity bills and keep your home warm and cosy in the winter.

Tailor-made to match your exact requirements, our casement windows can be made in virtually any height and width. Choose from an extensive range of window designs, frame and handle colours, as well as window board finishes.

Our windows come in a wide range of colours and are also available with a grained effect, which means they look like a traditional timber window, but have all the modern advantages of uPVC, such as being more secure and thermally efficient and virtually maintenance free.

Our most popular colours are; Rosewood, Anthracite Grey, Golden Oak, Irish Oak and Cream. All our colour choices are available with white on the inside if required.

But not with Sheffield Window Centre.

Our Sliding Sash Windows replicate the styling of timber box sashes so accurately that they are often approved for use in conservation areas. With a deep bottom rail, slim sashes, decorative horns, true Georgian bars and a slim mullion section, they actually enhance the styling of a traditional home. They also slide easily and smoothly, putting an end to the sticking and rattling associated with timber and, as an added bonus, they tilt inwards for ease of cleaning and ventilation.

Mock Sash Windows are an attractive alternative to the more traditional vertical sliding sash window. The top hung casement provides ventilation and can also be locked in the night ventilation position. The lower sash is a tilt and turn window, which can be opened inwards for ventilation and easy cleaning.

Our sash windows also bring with them all the benefits of uPVC such as low maintenance, improved energy efficiency and better security.

Our Flush Sash windows are specially designed so that the opening sash of your window sits flush with the outer frame, giving a unique sleek and seamless appearance.

Not only do Flush Sash windows authentically replicate the features of a traditional timber window, they also compliment more modern homes perfectly with their clear lines and minimalist appearance. From the traditional and highly textured Oak to the modern Anthracite Grey, you will find the perfect match for your home.

Choose from a traditional sliding sash, a uPVC mock sash, or a more modern design to complement the style of your home.

Our expert design and installation team can even create a bay window from a flat window to add a traditional feature to your home if required.

Unlike timber bay windows, uPVC replacements require very little maintenance and are far more energy efficient and secure. Of course, we always use strengthening bay posts on all of our bays, so you can rest assured that when replacing your bay window with our products, the structural integrity will not be compromised.
