uPVC Sliding Sash Windows

Style and Elegance
at the forefront.

At Genesis we have created an authentic sliding sash window that’s as near to the original timber versions as possible and provides a credible and low maintenance alternative.

Genesis sliding sash windows are authentic in virtually every detail and are widely regarded as one of the best alternatives to timber on the market today.

These beautiful sash windows are perfectly suited to many period properties, particularly for those older houses that are being renovated, such as Georgian, Edwardian and Victorian.

Because Genesis uPVC sash windows are so aesthetically pleasing and look so authentic, they are the perfect solution for older properties including those in conservation areas or with listed status.

At Genesis we are set up to design and craft sash windows that look and perform exactly to your specifications taking into account colour, size, features, hardware, security and energy efficiency choices.

Beauty and Performance meticulously crafted.

Our uPVC sliding sash windows are manufactured using modern materials and built using one of two jointing methods to deliver impeccable appearance and performance.

All of our sash windows have the option of deep bottom rails, decorative run through sash horns and astragal bar detail to respect the style and appearance of period properties.

With Genesis you have a sash window that adds period charm and is created in harmony with the style of your property and always perform well in any weather.

We can also supply arched windows with the sliding sash feature.

FAQ

The bottom rail is the section of profile that forms the bottom side of the bottom sash. This comes in 2 heights 60mm & 90mm. The 60cm standard bottom rail is often used in both newbuilds & period homes, while the 90mm deep bottom rail is very much associated with the traditional look in period properties.

Yes, you can have a different colour on the outside and inside and there are a number of dual colour stock combinations. In addition to this Genesis offers two other solutions. One is the special foil option and the other is our bespoke spraying service. If you have a particular requirement on colour combinations give our team a call to discuss the best option for you.

The manufacture of the corners of the outer frame and the sashes is a critical difference when comparing Genesis Vertical Sliders with others on the market. The seamless Graf weld looks amazing and is great for most applications including newbuilds and period property renovations. If, however, you have a listed property or it is in a conservation area then the fully mechanical version is likely to be a better solution.
The fully mechanical version is also selected by those wanting to have a window that looks as close to it’s timber couterpart as possible.
