Sash windows to be proud of – from Bygone

If you believe, like us, that original sliding sash windows are one of the most beautiful window styles of all time, you’re sure to appreciate the Bygone sash window collection from Masterframe – providing three pioneering sash window designs which reproduce traditional authentic sash features. All as faithfully as possible in modern materials and to the highest quality and with an eye to cost. This means that Bygone sash windows don’t just look great; they’re also energy efficient, extremely secure and built to last.


Symphony, Harmony or Melody… authentic windows for every occasion

Bygone brings you hundreds of different choices in design for frames, surrounds and glass. For example thin sealed units give a sleeker look, and Georgian surface-applied bars can be added in any configuration you may desire. Bygone Windows are great to match your existing or replacement window, or they can enhance your property by giving it some additional style. Whatever your idea, Bygone make the choice of window easy as 1, 2, 3. Start  by considering Melody with its authentic deep bottom rail. Take a step up to Harmony and add woodgrain finish as standard. Or aim high and reach the top note that Symphony offers with wood-style butt joints and so much more.


Whilst the foil finishes, frame and sash profiles are the same as those found on Symphony and Harmony, Melody is the one range that is available as a gloss UPVC option before moving up to the woodgrain options standard in the Symphony and Harmony ranges.

For authentic traditional style Melody comes with deep bottom rail and continuous run through sash horns. The glazed units are 24mm argon gas filled.

Cost options include white or antique cream woodgrain foil, painted colour match frames; also sandblasted, satin, etched or patterned glass; toughened, acoustic or laminated glass; and Victorian or Georgian bars. The internal glazing bead is standard ovolo.


The most versatile window in the range, Harmony has numerous optional extras available for individual customisation or to simply tailor your windows to a budget.

A standard Harmony window is constructed much in the same way as Melody. It has the standard 52mm transom, larger side members and deep bottom rail, however it has the option of the slim 39mm meeting rail found on the Bygone Symphony.

For authentic traditional style Harmony comes with deep bottom rail and continuous run through sash horns. Additionally it has a slim integral mullion. The glazed units are 18mm krypton gas filled.

Standard finish is white woodgrain foil but cost options include antique cream woodgrain foil, painted colour match frames; also sandblasted, satin, etched or patterned glass; toughened, acoustic or laminated glass; and Victorian or Georgian bars. The internal glazing bead is Bygone exclusive deep ovolo.


When it absolutely must look like timber because the planning officer is insisting or simply when only the very best will do, there is only one choice.

The Symphony is Bygone’s premier sash window, with every single timber effect feature fitted as standard.

Standard finish is white woodgrain foil but cost options include antique cream woodgrain foil, painted colour match frames; also sandblasted, satin, etched or patterned glass; toughened, acoustic or laminated glass; and Victorian or Georgian bars. The internal glazing bead is Bygone exclusive deep ovolo.

Glazing is one of the most important aspects of any window.

It can be transparent or opaque, stained or coloured and can even showcase geographical patterns and fashion trends.

Glass can say a lot about a window, which in turn can tell you a lot about the property and its inhabitants. Traditionally, large panes of glass meant wealth, due to the complicated nature of glass production in the 17th Century. Smaller panes were often saved for shop fronts and included bulls eyes, the centre of the spun glass and the cheapest part.

Stained glass and overly complicated Georgian bar designs were similarly a sign of wealth in Victorian Britain and there are examples of this all over the country, but especially in the capital and more salubrious areas.

Glazing itself has had to change with the times and other qualities are now more important to the modern home owner. These include acoustics, thermal efficiency, security and durability, often dictated by ever changing building regulations and planning laws.

Not your average double glazing

Double glazed sealed units are made up of two panes of glass and a gas filled cavity. In the window industry 24mm Argon filled glass units are widely used in sash windows, but we always seek perfection.

Slimmer window designs use an 18mm krypton gas filled glass unit with a 10mm cavity. Appearing slimmer, it also allows for a deeper glazing bead and Georgian bar on the inside of the window.

Patterned glass does not allow for both a Low E and Low Iron coating, but we will always ensure that U values and WER ratings remain as high as possible on each individual window.


Triple glazing? Nope!

To retain the good looks of a traditional sash window there simply isn’t enough space to insert a triple-glazed unit. The ultra slim frame and beading would ‘disappear’. Instead the manufacturers have ensured their double glazed units offer excellent thermal efficiency.

There are, however, choices of privacy glass and coloured glass.

Glazing designs

Obscured or etched glass can be a stylish decorative feature and is fast becoming a popular choice among architects, designers and home owners. There is a wide range of patterns and levels of obscurity available, from the standard textured glass patterns to more expensive etched ranges.

There are practical glazing options on toughened, laminated and acoustic glass to make sure that your new sash windows perform in exactly the way that your property and situation require.

With certain Georgian bar designs coloured films give the impression of stained glass, or possibly incorporate your own refurbished stained glass panels inside new double glazed units. This is also sometimes possible with original leaded glass panes, but do consider the extra weight.

This allows you to preserve the glass design of your windows to match the neighbours and retain the period character of your property.

Colour options

Together with our authentic colour finishes, our fabulous range of colours will fully complement and truly enhance your replacement windows. County offer a great range of colour options including whitegrain and classic cream, green, through to grey, light oak and black, creating the ultimate style statement for your new windows.

More and more people are choosing the coloured look. While brilliant white has the smooth finish of gloss painted wood, County Windows’ coloured frames have a natural woodgrain texture that looks and feels like traditional stained timber. In fact, it is only by touch you can tell these are actually high security, virtually maintenance free UPVC.


The crisp, clean looks of plain white PVC-U is perfect for the majority of homes. Mimicking gloss painted finish it’s still the first choice for many customers wishing to retain the original colour of the windows in their home.

Or coloured?

With modern production techniques anything is possible!

We can supply Bygone windows, with or without a grained appearance, in any number of ‘closest colour-matched’ paint options. Colours are available from the standard industry charts such as the RAL colour chart and various other popular branded charts. We can even colour match to Farrow & Ball.

More than one colour?

Normally we spray entire windows, however we can offer different colours externally to internally and different combinations from sash to frame. A black frame with white sashes is quite popular, whilst we have also sprayed combinations of blue and white or cream and maroon.

When the outside of the window is a different colour to the inside, we mask up and spray the balance chambers to the desired colour, so only one colour is visible from either side when in the closed position.

Our two-part chemical cured paint is far harder wearing than water based paint, as we believe durability is paramount. Standard household decorator’s paints should never be used for painting PVC-U.

Rising energy bills have fast become a key concern for millions of homeowners. The windows installed at a property have an essential part to play in keeping fuel costs down.  If you install windows without the energy efficient qualities as those from County, then the home won’t be as enjoyable throughout the year and your energy bills will be higher.

Whether you want a ‘C’ rated version, or the ‘A++’ rated variety, leave it with us.

Noise Reduction

It’s not just intruders or inclement weather you want to keep out when considering replacement windows; you will also want to reduce unwanted noise from the outside world entering your home and disturbing your enjoyment. This is particularly pertinent in built up areas or near busy roads, but is also an important consideration for most new home improvements. All our products are designed and built with this in – our experts always know to consider this when guiding you about your options for your new windows.
