Sash Windows - An historical perspective
There cannot be a more quintessential style of window. Simple in design, elegant in proportion, vertical sliding sash windows remain the most beautiful and energy efficient style of window ever created!
First introduced in the mid 1600's, wealthy home owners installed sash windows and the larger the glazed area, the wealthier they were. New sash windows replaced casement windows in 16th century properties.
However, since the 1960's the indiscriminate replacement of sash windows using mass-produced windows has meant that thousands of beautiful sash windows have been lost, destroying the character and value of many properties in the process.
Yet this style of window remains the most energy efficient ever invented.
The Bygone Collection have faithfully blended the beauty, proportions and elegance of original sash windows with cutting edge materials and manufacturing techniques to produce stunningly authentic sash windows meeting all today's stringent requirements.
Requirements such as strict conservation area controls, energy efficient glazing, Police recommended security testing and endurance testing by the British Board of Agrement.
Bygone creates bespoke, purpose made, individually designed sash windows, custom built to your precise specifications and expertly installed by South Lakes Windows Ltd - faithful to the spirit of the past 300 years of history.
Conservation
A replacement window made from modern materials such as UPVC may seem to fly in the face of history, however today more conservation officers and planning inspectors are convinced by Bygone sash windows because of their looks, but also because they can exceed the demands of energy efficiency, security and recycleability.
When most hear the words "UPVC" they instinctively think of the thousands of casement windows that were installed in the early 1980's when double glazing first became popular. This has damaged the charm and character of many buildings.
So authentic is the effect that a senior planner standing just feet away from a Bygone sash window actually said, "I don't want timber - I want a UPVC sash window", he couldn't believe his eyes seeing our white acrylic timber finish!
On occasion timber sash windows are the only accepted replacement material. The Bygone Collection can provide these too with enhanced thermal efficiency and greater security than the original sashes.

Don't be tempted by cheap double glazing
Many cheap upvc replacement sash windows spoil the character, charm and feel of homes because they are not balanced. It's hard to describe but cheap sash windows or inappropriate window styles simply destroy the aesthetics (and value) of properties.
Replacing the entire window, not cutting corners by leaving the old frames in situ, guarantees the character will remain in tact.
With The Bygone Collection from South Lakes Windows Ltd you can be assured that the glass panes will be equal in both sashes giving the same balanced appearance and elegant proportions as the original craftsmen desired.
White Woodgrain Effect Sash Windows
Bygone sash windows have been designed to cope with driving rain, howling winds and to prevent water forcing its way into your home.
Authentic Appearance - White Painted Timber effect
An authentic grained effect which creates a stunning painted wood appearance with the low maintenance benefits of PVC-u.
Unique Design - Surface mounted, bonded external Georgian bars
The Georgian bars that create each pane are crucial to the authentic look of a upvc replacement sash window. Only one thing achieves that result - authentically shaped, securely fixed, surface mounted external glazing bars.
The Bygone Collection uses a patented method of interlocking the Georgian bars together before clamping them to the glass with a "Georgi Clip ™". Our sash window bars are guaranteed to stay firmly attached.
Unique Design - Torso Balances
Balances are the engine that provides extra assistance to make it easier to open and close heavy sashes.
TORSO balances are guaranteed to open for at least fifty thousand cycles, that is three times a day for the next fifty years!
Unique Design - Tilt Restrictors
Cleaning Bygone sash windows is safe and easy. The unique dual tilt restrictors on a Bygone window means each sash can be tilted back for easy and safe cleaning from the inside.
Why are our Sash Windows so authentic?
Authentic Appearance - Continuous Horns
The victorians introduced horns in the 1850's to prevent the sash weights from damaging timber window frames as sash windows gained extra weight from the thicker and heavier plate glass.
With cheap upvc sash windows manufacturers are happy to just mimic this important original feature by sticking on "replica" horns. This is one of the many "artificial" details planners find most objectionable.
Not anymore. Bygone sash windows have integrated continuous horns, which are so essential to achieving a truly authentic sash window appearance.
Authentic Appearance - Deep Bottom Rail
Traditionally the bottom rail on the lower sash was far deeper than it's side members, constructed from 4 or 5 inch timbers the lower rail carried most of the sash weight.
It's far easier and cheaper for manufacturers to weld sashes without this feature. However this simplistic approach destroys the authentic appearance.
Bygone replacement PVCu sash windows are uniquely constructed with deep bottom rails to maintain this crucial detail, so important in maintaining the look and value of your home.
Unique Design - Traditional Bespoke Cam Catches
Cam catches are a weak point on and sash window and were easily opened by unwelcome visitors. Bygone have specially developed solid locking catches, secured directly into steel reinforcing within the sash.
Unique Design - Simple, Effective, Limit Stops

Limit stops are devices that prevent a window being opened beyond 100mm initially, an important safety feature for young children.
UPVC Sash Window
Energy Efficiency
By opening both upper and lower sashes the cooler air coming through the window sinks to the floor and forces the lighter, warmer, moisture laden air up towards the ceiling and out through the upper sash opening.
Studies have concluded that the design of sash windows is more than 25% more effective than any other style of window in the same aperture.
Energy efficient and environmentally friendly
We must all conserve the heat we produce, the energy used in doing so, and reverse the rise in CO2 emissions.
The Bygone Collection was the first window of any kind to obtain certification from the Energy Savings Trust.
Endorsed with the Energy Saving Trust certification.
Bygone Windows Sash Windows (C rated) are recommended because they are proven to reduce heat loss by 74%. The B rated option even higher! Helping reduce your heating bills.
According to the Energy Savings Trust 20% of the heat lost from an average home occurs through the windows.
British Fenestration Ratings Council rated
All Bygone C rated energy efficient sash windows have triple chambered sash profiles for superior thermal properties, low iron glass on the outside soft coat Low E glass inside. Combined with argon or krypton gas filled sealed units, energy loss is kept to a minimum.
A Greener PVC-U
Lead has been needed as a stabiliser in previous UPVC extrusion - An undesirable situation.
Rest assured your new Bygone sash windows will be virtually lead free as we now use calcium as an organic substitute.
Sash Window Security
To be considered secure, a sash window must pass BS7950. The Bygone Collection by Masterframe was the first sash window to pass this British Standard and shortly after Masterframe obtained the "Secured by Design" endorsement.

To achieve the Secured by Design endorsement Bygone windows were subjected to vigorous attacks, with each corner and locking point tested in turn. This earned Masterframe (Bygone Windows Suppliers) to become acredited members of this endorsement.
The force used during this attack was the equivalent of four 12 stone men hanging all their weight downward, with another one and a half men attempting to force the sash horizontally - a massive force!
