UPVC Sash Windows

Do you have tired and draughty wooden sash windows that need replacing, but don’t want to change to a different style of window? Want to retain the character of your home or return it to the style it once had? Our UPVC sash windows are a perfect, low cost option for you. With the notable features of a traditional sash window – the two panes of individual glass positioned in vertical grooves that slide up and down; one in front and one behind, UPVC sash windows now give you all the timeless elegance of a traditional sash window, with superb sound and heat insulation, no draughts and without the hassles and maintenance of your old sash windows.

Here at County we provide you with the best quality sash windows and work with you to help finalise every aspect of your design, from size and finish to the best use of Georgian or cottage bars. We’ll ensure you get the window that perfectly suits your home.

The window company for homeowners in Sussex & Kent

When replacing windows it’s important to choose the right home improvement company, one offering plenty of choice so that you get a design that ticks every box. At County, we have windows available in a variety of different frames, colours and styles; there really is something for everyone. The installation of windows will give your home a whole new lease of life, so why bother moving? Just get improving.

From the first point of contact, right up until the fitting of your windows, County can guarantee you the very highest standard of service.

Energy Efficiency

Rising energy bills have fast become a key concern for millions of homeowners. The windows installed at your property have an essential part to play in keeping fuel costs down. If you install windows that don’t have the energy efficient qualities of County’s windows, keeping that precious heat in, then your living space won’t be as enjoyable to use in the winter months and your energy bills will be higher. At County all of our windows come with self-cleaning active glass as standard, or they can be upgraded to Celsius glass for further improved heat reflection in summer and heat retention in winter.


At County, we’re all about peace of mind, which is why we only offer windows that are manufactured using the latest technology, techniques and security features. Our products are beautiful to look at with exceptional performance across the board, excellent reliability and above all are highly secure, giving you peace of mind when you’re away. You can be rest assured that you, your family and possessions will stay safe.

Noise Reduction

Further to security and energy efficiency, we understand that a major factor when considering replacement windows, is the ability to reduce unwanted noise from the outside world. This is particularly prevalent in built up areas or nearer busy roads. All our products are designed and built with this in mind using sealed unit glazing, and our team of experts always know to consider this when guiding you through your options for your new windows.

Choose between a traditional or contemporary frames…


Windows with UPVC frames are the natural choice for many people for their low maintenance and thermal efficiencies. UPVC is often perceived as not being quite as aesthetically pleasing as other options. With latest technologies, a wide range of colour options, the range of woodgrain effects that can be applied and the super choice available, UPVC windows have never looked so good!


What do we mean by heritage?… Heritage is a traditional styling that can be applied to all types of material. A heritage style can be applied to UPVC frames using woodgrain effects and timber joints, giving them a traditional look and feel.

We provide all types of glazing options, even privacy glazing…

Purchasing a set of windows may seem a daunting prospect financially, but you need to view it as a long-term investment and consider how much money they will save you over their extensive lifespan.

Modern day windows with double or triple glazing are highly energy efficient and will add character and value to any home.

Double Glazing

Rising energy bills have fast become a key concern for millions of homeowners. All of our windows come with double glazed, self-cleaning active glass as standard, or they can be upgraded to Celsius glass for further improved heat reflection, heat retention and UV protection.

Whichever double glazing option you go for, your new windows will play an important part in keeping fuel costs down.

Triple Glazing

Rising energy bills and unpredictable weather has led to the rise in popularity of triple glazing. That extra pane of glass can make a huge difference to fuel costs and the warmth felt inside your home. Whilst it costs more than traditional double glazing, you will get more than your fair share back in monetary terms. Which ever style of window you go for, triple glazing can be integrated into it.

Glazing Bars

All UPVC sash windows are made to measure specifically to the requirements of you and your home, this includes fully customisable glazing bar designs.

Colour finishes

Our wide range of colours and authentic finishes will fully complement and truly enhance your replacement windows. County offers a great range of colour options from whitegrain and classic cream, to green, grey, light oak and black, just to name a few. We will even spray finish to your chosen colour if you wish! You would be amazed how adding a bit of colour helps your new windows to create the ultimate style statement. Whilst brilliant white has the smooth finish of gloss painted wood, more and more people are choosing coloured frames for their windows. These frames have a natural woodgrain texture that look and feel like traditional stained timber. In fact, it is only by touch you can tell these are actually highly secure, virtually maintenance free UPVC frames.

UPVC Colours

In addition to our coloured woodgrain range, we can create or match any colour you like for your County windows. The colour coating is a specially developed paint that is sprayed on and bonds perfectly to the UPVC, giving a smooth satin finish that forms an extra protective coating that never needs re-painting.

Heritage Colours

Timber has a quality all of its own and it’s a look that many homeowners aspire to have on their property. Thanks to our heritage range which perfectly mimics the 19th Century traditional timber windows, you can. They come in a selection of period colours including clotted cream, cotswold biscuit and painswick. For full authenticity try our English, Irish and silvered oak colours or for a slightly more modern take we have colours including corse lawn and eclectic grey.
