08/03/2024Restoring and Maintaining Historic Sash Windows in Ireland’s Protected Structures
03/04/2024When it comes to home design, certain elements never go out of style. With their classic design and functionality, sash windows have been adorning homes across Ireland and the UK for centuries. What is the enduring appeal of sash windows and how do they add elegance and sophistication to a property?
A Brief History
Sash windows have a rich history that dates back to the 17th century in Ireland. Originating in Europe, these windows quickly gained popularity and became a staple in Georgian and Victorian architecture. The earliest sash window found in Ireland dates to 1680 in Kilkenny Castle. The classic design features two movable sashes that slide vertically, allowing for easy ventilation and a seamless connection to the outdoors. The term “sash” is thought to have come from the French word “chassis” which means “frame”.
Architectural Beauty
One of the key reasons for the enduring popularity of sash windows is their architectural beauty. The symmetrical proportions and clean lines of sash windows add a sense of balance and harmony to any home. Whether your property is a period or contemporary residence, sash windows can effortlessly enhance the aesthetic appeal. They are indeed a sought after feature in Irish homes.
Their early appearance in the Georgian era worked well with the Palladian style of architecture which had it’s roots in mathematics. Buildings from this era followed an exacting symmetry that is known to be pleasing to the eye. The sash window provided the perfect window style as it opened vertically which maintained the unbroken flat fronted facades. Additionally, it allowed for the largest glazed area with the slimmest timber astragal bars.
Versatility and Functionality
Sash windows are not just visually appealing; they are also highly functional. The ability to open both the top and bottom sashes provides excellent control over airflow and temperature regulation. This makes sash windows a practical choice for any season, allowing you to enjoy a comfortable living environment all year round.
They are particularly suited to the Irish and UK climates as they are don’t blow in the wind. You can choose to ventilate a room from the top or the bottom sash only, or from both.
Ventilation is important in all buildings to avoid ill health. In Georgian times the government imposed a window tax and also a glass tox on homes. To avoid paying an excess, people boarded up windows which caused widespread outbreaks of illness such as smallpox. In the end, it was the pressure from the physicians that caused parliament to repeal these taxes and replace them with the property tax.
In more recent times, during the peak of the Covid pandemic, we were encouraged to open our windows as much as possible to prevent spread of the virus indoors.
Energy Efficiency
In recent years, sash windows have undergone advancements in design and technology to improve energy efficiency. With modern materials and double-glazing options, sash windows can now offer improved insulation, reducing heat loss and minimizing energy consumption. This makes them an eco-friendly choice for homeowners who want to reduce their carbon footprint and live in more comfortable homes.
It is worth noting that protected structures or houses in architectural conservation areas (ACAs) as defiend by your local authority, will require planning permission for any alteration to windows. If the original glass is still in situ, it is important to conserve it. Not only does it add to the character of the property, but it also allows a beautiful soft, dappled light into the rooms – which can never be acheived with modern float glass.
Also, the Department of Heritage recently publsihed new guidelines for Increasing Energy Efficiency in Traditonal Buildings, which has interesting information on improving the U-values of old windows by closing shutters or curtains and by adding secondary glazing.
Maintenance and Longevity
Contrary to popular belief, sash windows are not high-maintenance. Windows will always benefit from an annual wipe over the surface to remove insects and debris. This is also a good opportunity to check for any signs of damage and effect minor repairs or painting as needs be.. With proper care and regular maintenance, they can last for decades (a study at Herriot Watt University in Edinburgh states that a typical timber windows lasts at least double the life expectancy of a uPVC window). We see windows that could be 200 years old that are still in good condition. Old timber has incredible longevity as they are made from slow grown pitch pine.
The ability to remove the sashes for painting and repairs makes cleaning and maintenance easier, ensuring that your windows stay in pristine condition for years to come. We recommend an annual wipe with a damp cloth and a visual inspection to check the condition of the timber and smooth operation of the window. We provide a maintenance guide with all windows.
Sustainability
Choosing timber frame windows is an environmentally friendly choice. They can last decades if not centuries with correct maintenance, they are reapairable, repaintable and recyclable at the end of their life. Timber is the only completely sustainable building material on the planet, as we can grow more as we use it. Additionally, as we choose more timber options for our homes, it encourages the growth and production of more timber
In a world where trends come and go, sash windows continue to stand the test of time, offering a timeless elegance that never fades. With their architectural beauty, versatility, functionality, energy efficiency, and longevity, sash windows are an investment worth considering for any homeowner.
Timeless Sash Windows offer a bespoke service for both new and restoration windows. Our surveyors will visit your property to advise you on the best course of action. In many cases, the restoration can be at a similar price point to the manufacture of new windows due to the work involved. Planning requirements may also dictate the decision.
