Generation Windows supply and install replacement windows in a huge variety of styles and finishes. Whether you need uPVC windows as a reliable, inexpensive option or a set of sash windows to complement your period home, they supply perfect solutions at exactly the right price.

Sash Windows

If you are going for the traditional or classic look, then Generation Sash windows will be the perfect choice for your property. Sash windows operate using movable panels which typically slide up and down. 

Double Glazing

Double glazing effectively improves thermal and noise insulation around your home, providing you with more peace and helps to warm a property in winter but also keeps it cooler in summer. Double glazing also reduces the cost of your energy bills and increases security.

Casement Windows

Despite dating back to the 16th century, casement windows are one of the most common options available today, as they are an affordable, cost-effective option for maximising external air intake into your home. 

Tilt And Turn Windows

The Generation Windows ‘Tilt and Turn’ range provides you with security and an abundance of natural light for lovely, open views. Replacement windows allow you to use the tilt function and to ventilate your room securely without letting anyone see inside or allowing them to gain forced entry into your home.

Secondary Glazing

Secondary glazing is ideal for use on historical buildings and conservation areas where double glazing is prohibited. Secondary glazing involves the installation of an extra pane of glass on the inside of an existing single-glazed window. Just like double-glazing windows, secondary glazing increases insulation performance and reduces noise but can still maintain the traditional look of single-glazed windows. 

Triple Glazing

By adding an extra pane of glass to your window, the noise and thermal properties of triple glazing improve upon those of double glazing. Hence triple glazing is a popular choice in continents prone to particularly cold winters.

Generation Windows offer customers a wide selection of doors for different uses and applications.

Bi-Folding Doors

Thanks to their combined design appeal and practicality, bi-folding doors have massively increased in popularity over the last 10 years and are now a must-have feature in many new builds.

Our Bi-folding doors are amazingly versatile and are a great way to keep an open divide between the interior and exterior of your home. Providing wide openings of up to 90% of their length they promote natural light and airflow.

Composite Doors

Generation Windows offer a stylish range of composite doors and side panels that can be custom-built to your requirements. Composite doors are manufactured using high performance thermoplastic and insulation materials, resulting in a strong, attractive product that provides key benefits.

Composite doors provide outstanding thermal efficiency, an advantage that wooden doors cannot match. All composite doors offer security and protection, weather resistance, low maintenance and durability in a single, attractive package.

Sliding Doors

Sliding doors are perfect as entranceways to garden patios and provide the added benefit of maximising natural light intake. Sliding patio doors also allow amazing views of gardens. Gen Slide is a great alternative to French doors if you require a high level of security without compromising the feeling of space. 


Conservatories are an affordable way of adding natural light and a larger sense of space to your home. As they are largely exempt from the need for planning permission, conservatories can be purchased and fitted with ease by the experts at Generation Windows. 

Generation Windows design their conservatories to match your home regardless of the style. Their range includes designs from the Georgian, Edwardian and Victorian eras. Whichever design you choose, what you always get from Generation Windows conservatories is a seamless extension of your living space which also brings in an abundance of natural light.


Orangeries differ from conservatories as, generally, they are different to the design of the house and traditionally involve lots of brickwork, large windows and a glass roof.

Orangeries tend to be made from timber, whereas conservatories can be made from a variety of materials including uPVC, aluminium or timber. Generation Windows orangeries use modern technology to ensure that you can use them every day of the year.
