What are conservation area rules for windows?

Replacing sash windows is pretty straightforward. Unfortunately, when you live in a conservation area, that makes the matter far more complicated. You wouldn™t think windows would cause too much trouble for homeowners, but homes built within a conservation area need special permission to be replaced or repaired. So, what are the rules for windows in a conservation area?

Permission is needed for all sash windows

Regardless of whether you want to upgrade or repair old windows, they are likely to require special planning permission from the local authorities or conservation board. It™s a huge challenge because double glazing and UPVC windows are typically banned in conservation areas. The reason is down to the fact that conservation is there to protect the look of the original building. So, every little change (to the exterior) must be sympathetic to the original design.

It means replacing old sash windows becomes tougher, although not impossible.

Is planning permission necessary for all conservation areas?

In simple terms: yes, you are typically going to need permission to make any alterations or changes to windows in conservation areas. Typically, local authorities want to see more like-for-like repairs than new window installations. That doesn™t mean to say you can™t repair old sash windows on your property; you just have to do so in a manner that™s in line with current guidelines.

Understanding the guidelines

Planning applications are necessary to install new sash windows. Remember, if the new windows ˜destroy™ or are considered a ˜threat™ to the character of the building, your application may be rejected. It is, however, possible for you to install UPVC windows even in a conservation area. Of course, the number one rule to this is that the new windows cannot be significantly different from the original design.

Why are there restrictions in conservation areas?

Conservation areas were created to protect and preserve historical buildings. It can be a great thing as period properties (that hold lots of historical value and beautiful designs) are preserved for the next generation. Of course, there are drawbacks to conservation, including issues replacing old sash windows.

It™s important to seek advice before installing new windows or making any changes to the building. You should also understand the local restrictions and laws when it comes to conservation. Typically, if your new windows are in line with the old sash windows, your application shouldn™t run into difficulty (not much, anyway).

Know where you stand before you make any alterations

Buying a listed or protected building can be wonderful because it™s a part of history. Some of the original features can be gorgeous and priceless in many ways. Of course, there are issues with making changes, especially to the exterior of the property. You™ll need special planning permission to alter the windows of a listed building or one that™s within a conservation area. Fortunately, with a little know-how, you can install new sash windows or make repairs with little effort.

How to winter-proof your sash windows

As energy bills are rising, and temperatures are dropping, you might be thinking about ways you can make your home more energy efficient. One of the things you might want to think about is your sash windows. While floors, walls and attics can be easily insulated against winter heat loss, windows are one of the biggest culprits of causing icy homes. Here are some of the ways you can winter-proof your sash windows¦

Hang thermal curtains

Thermal curtains are a great way of retaining warmth in your rooms. They form an insulated barrier against cold windows, trapping old air between the glass and the window, preventing it from entering your home. If you want to make the most of the sun (on those days it™s out), don™t forget to open your curtains on sunny days so the heat can shine into your house.

Reseal your windows

Even a quick whip around with caulk can make a huge amount of difference when it comes to winter-proofing your sash windows. Keep an eye out for thin cracks or gaps around the edges of your window joints and caulk these to prevent icy drafts from flowing into your rooms. If you are looking for a more permanent solution, gaps around your windows may indicate you are in need of sash window repair.

Apply a temporary window film

A window insulation film is made of thin, transparent plastic (quite like cling film), which is applied to windowpanes before being heat shrunk using a hairdryer. This creates a close fit around the windows that can be useful for draught-proofing windows in winter.

Upgrade your sash windows

Naturally, the ultimate way to winter-proof windows is to upgrade them to double-glazed timber units, which are specially designed to keep the heat in your home. Double glazing works with the air itself which acts as a poor conductor of heat, trapping an insulating blanket of air between the panes of the glass. This layer of air acts as a barrier, keeping your home warm.

To further improve insulation you can install double-paned glass which will prevent any air leakage.

Highly Durable

It doesn™t matter if it™s heavy, rain, snow, frost or blistering heat, wooden windows are incredibly durable. In contrast to metal windows, they have the ability to expand and contract during various temperature fluctuations.

Hence, wood sash windows are designed to withstand a large array of weather circumstances and avoid any seal failures between the window and glass panes. The less air that gets into your home the less you will rely on indoor heating and the less your energy bill will cost.

Additionally, wood windows are unlikely to crack due to being tightly sealed unlike alternate windows such as vinyl.

Should I Repair Or Replace My Sash Windows?

Sash windows are a common feature of houses in the UK. Despite looking aesthetically pleasing, over time they can become less energy efficient. But how do you know when it is time to invest in sash window repair or replace it altogether?

How You Can Repair Sash Windows

A common problem with older sash windows is the lack of insulation they provide. Single, glazed panes can wear down and become draughty which may lose heat from your household.

However, you can easily fix this problem by upgrading to double glazing instead. This can be done without replacing the sash window.

Repairing your sash window with double glazing allows you to trap a greater amount of heat. In addition, two strong panes trap a gas between them like krypton or argon which forms a superior barrier between the warm inside and cold outside. This prevents thermal bridging and condensation, both of which can make a home much cooler.

Sash window repair is an investment, yet in the short term, you will have a warmer house, lower energy bills and won™t need to get rid of your existing window frames.

Why You Should Replace Them

Notwithstanding, there are situations where you are better off replacing your sash windows.

Upgrading your windows with better materials increases the chances of it lasting longer. For example, modern glass is very durable and newer frames are more resilient when it comes to water damage and rot. So you won™t have to worry about window repair for a long time.

Another reason is if your house is extremely cold or droughty. Modern sash windows are much better at preventing heat loss. Double glazing makes it more difficult for air to get through while high-quality timber frames are less likely to swell.
Finally, sash window repair could be the more expensive option long term. After all, an old window may need regular maintenance to ensure it is still working properly. In contrast, a one-off investment of new, modern windows will keep your home warm for years to come and simultaneously lower energy bills.

How to Choose the Right Sash Window Company for Your Home

Georgian, Victorian and Edwardian Sash Windows

There are three main types of sash windows in Britain, and these have been an architectural feature for over 200 years. These windows can tell you a huge amount about the history of a property. 

As home owners become more interested in conserving the historic features of their home, they spend more time maintaining and caring for their sash windows, and they may become more curious about how old their sash windows are, and what they have seen throughout their history. 

Types of Sash Windows

Single hung sash windows are the oldest design, these date back to Georgian times, they have only one section and this moves with a single pane of glass.

The Georgians were also responsible for developing this style into double hung sash windows. These were then taken on into the Victorian and Edwardian age. These windows feature panes placed in a variety of arrangements including six-over-six, four-over-four, nine-over-nine and six-over-two.

There are also horizontal sash windows, these have two sashes that slide sideways, as opposed to up and down. This design is far less common than conventional sash windows, so if your house features these you are very lucky.

If you have been unable to match your sash windows to the above designs, your architect may have gone rogue and added their own personal touch.

Periods of Sash Window Design

Georgians particularly adored the six-over-six design of the double hung sash window, they also introduced smaller panes of glass that were separated by glazing bars.

Victorians, in contrast, preferred one large pane of glass. They chose to feature their larger sash windows on the ground floor, and smaller sash windows on the upper floor. 

Edwardians adopted a, somewhat random, multi-pane approach, they used multiple panes of glass on the upper sash and a single pane of glass on the lower sash.

Whichever style of sash window your home features, we can help with sash window restoration, ensuring they look as good as the day they were designed.

How Do Sash Windows Work

Sash Window Operation Instructions

Sash windows are vertically opening windows that consist of two framed window sashes, one positioned in front of the other. This style of window unit sits in frames with vertical grooves, which allow them to move up and down smoothly. The up and down movement is assisted by counterbalances which are weights on cords and pulleys.

When closed, the top and bottom sash will be locked together at the midrail to prevent them sliding. There may be handles attached to the sashes to help you open them, depending on the window design.

The window can be opened by sliding the bottom sash upwards or, if you have a double hung window, by sliding the top sash downwards.

Sash windows can be fitted with complex hinge systems that allow the window to be locked on one side while the counterbalance on the other side can be detached. This is a helpful feature that can allow the window to be opened to let fresh air into your home, to get out, or to clean.

The design of sash windows also have benefits such as:

  • They look good: they follow a smart aesthetic and increase the value of the building.
  • Sash windows are safe & secure: only one panel can open at a time meaning that they are a lot more difficult to break into than cement windows. It is also easy to have additional features added for safety precautions such as locks and child safety devices.
  • Low maintenance: modern sash windows have a very low risk of warping and rotting as they are made of metal and plastic. You don™t need to sand them or apply coats of varnish either. More traditional sash windows are made from wood, but with appropriate care and maintenance they will have a long life.
  • Environmentally friendly: timber-framed windows are environmentally friendly as it uses the lowest amount of energy in its processing, production and transport. It also has a very long life-span meaning it won™t have to be replaced as regularly as other windows.
