The Changing Design Of Sash Windows Through History

Sash windows have been a popular architectural feature in Britain since the late 17th Century and the design of the window has been modified over time as the technology and building materials available have improved. Original sash windows can still be seen on historic buildings. Through the historical development of the sash window a lot can be learned about cultural history and crafts.

The concept of the sash window originates in Europe in the middle ages when sliding, glassless panels were used to cover windows. It was not until the sixteenth century that glass came to be used and a balancing mechanism was developed that enabled vertical sliding sashes to replace their horizontal forerunners.

Because of the expense of both glass and skilled craftsmen to do the work, only the rich could afford to have sash windows built in their homes. In the late sixteen hundreds, having sash windows became an increasingly popular way of showing off and it is during this time that they came to proliferate in Britain.

Originally, the windows were produced with numerous small panes of glass, held in place by crossbars and they were particularly heavy items. Improvements in the glass making industry later enabled wider panes to be made from a single sheet. A tendency to use a couple of large sheets instead of multiple small ones emerged and became more financially viable after the taxation of glass ceased in the mid eighteen hundreds.

The basic appearance of the sash window remained the same through most of the 18th and early 19th centuries with the most popular form being the “six over six” window. This featured two sliding frames, one over the other, and containing six panes of glass each . In the early 1700s, designers favoured an arch over the top of the light, but this reverted to the rectangular shape in the latter part of the era. Hidden boxes recessed into the window frame to hold the mechanism were developed later without altering the outward appearance of the window.

During the regency period a variation of the “six over six” design enjoyed a period of popularity with a much larger central pane surrounded by smaller ones. Such regency windows provided an opportunity to show off the wealth of the owners as they required at least two larger panes of glass.

A later feature of sash window frames that emerged in the nineteenth century was brought about by the size of the glass panels and the extra support that they required. To achieve this, the sides of each frame were elongated into horns. Although having one or two bigger panes was affordable and popular in the second half of the century, there was also a return to multiple panes among those who wished for a more antiquated look.

Since the nineteenth century, window manufacturing continued to evolve and the material needed became cheaper to produce. With less restrictive laws governing the placement, shape and size of windows, architects became free to choose from a range of historical styles to suit the look of each building, sometimes deliberately copying the designs of previous times.

The historical development of the sash window has gone alongside important changes in society and technology. A great deal of history can be learned from simply looking at the windows of a house as they often give clues about the status and taste of the people who had them built.

Double glazed widows are definitely a good thing. Whenever someone is comparing double glazed sash windows to single glazed windows they probably already know what they want.

What’s really happening is the the person who appears to be comparing is really trying to decide if he should take the leap and install the windows he really wants. It’s not like he has to compare one pane of glass to two. One is one less than two.

Is it possible that people are trying to compare cost effectiveness? That makes a lot of sense. Installing double glazed windows costs money. It costs more than installing single panes.

On the other hand, double glazed windows can save the homeowner a ton of money on heating and air conditioning bills. It’s pretty common knowledge that most of the heat transfer, out in the winter, in during the summer, takes place through the windows.

Some of it can be managed with big heavy curtains or drapes. Of course they also block out light and generally in the winter you want all the light you can get. In the summer, well, it’s nice to be able to see then too.

Double glazed windows consist of two panes of glass with a space in between. The space filled with gas or air does not conduct heat well and therefore slows down the transfer from inside to outside. People who install double glazed windows will quickly notice a savings on their heating and cooling bills.

Double glazed windows keep out noise as well as preventing heat from escaping. That is something to keep in mind along with the money that will be saved on the heating bills.

Double glazed windows could add to the value of your house. Many home buyers are looking for homes that are environmentally friendly. They also want to be comfortable and keep their costs down.

Double glazed windows could actually decrease the value of your house if it is historically important. In fact you might not be permitted to install double glazed windows. There might be restrictions limiting what changes you can make. However many historically concerned groups have become aware that people are reluctant to purchase older homes because they are damp and drafty. Carefully crafted wood sash windows with double glazing can be made to match the original architecture and make the home more comfortable to live in.

Right about getting now, you are probably thinking about getting double glazed sash windows because you know how lovely sash windows can be and you are right.

Comparing Double Glazed Windows With Single Glazed Windows

One way to manage temperature control in buildings is through maximizing retention of heated or cooled air. Depending upon the season, it is important to retain cool air in the Summer months, and warm air in the Winter months. When determining factors which are helpful in achieving that purpose, comparing double glazed sash windows to single glazed windows can show the advantages they offer.

Application of reflective or tinted coating was an early attempt to insulate windows. The layer blocked some of the glare and heat from the Sun. Other chemical treatments somewhat helped to enhance occupant comfort. Older houses usually had sash windows, which were made of 2 big glass panes built into wooden frames. As the wood wore over the years, the glass panes were no longer sealed properly, so most buildings were drafty and uncomfortable.

More modern buildings usually have doubled panes, built into frames, where a vacuum or gas forms insulation between them. Thus, air remains at a more comfortable temperature. The ability to control the consumption of energy for heating and cooling, positively affects the cost of fuel. There is an acoustical advantage produced by double-paned windows. Outside noise is minimized, and creates a much quieter environment, especially near railways, airports, athletic arenas, etc.

Security is another factor in choosing types of windows. It is logically much easier to pry open a single paned window than a much more durably constructed double paned window. Even the locks are significantly heavier and safer. When there are pollutants in an area, it may be comforting to know that well-insulated windows are more likely to protect building occupants. Toxic chemicals, vapors, allergens, automobile emissions, and other potential health threats are minimized when they can’t enter through windows and affect people.

Environmentally friendly, double paned windows retain heat in the winter and preserve cool air in the summer. That feature is one that is vitally important to anyone who is conscious of the consumption and depletion of fossil fuel supplies. With better insulation, there is less need for wasted energy.

Newer, insulated windows generally look better than older, worn out wooden or metal windows. Real estate increases in value when buildings have better curb appeal.

Choosing the right type of window is instrumental when the goal is to increase comfort, save energy costs, improve security, and lower noise levels. Comparing double glazed sash windows to single glazed windows can help in making an effective decision.

For top energy efficiency, you should consider double glazed sash windows rather than single glazed. Sash windows allow for natural flow of air, thus reducing your energy requirements even further.

Some Interesting Trivia Everyone Should Know About The Origins Of The Sash Window

Wednesday, September 8th, 2010

Optimize Search Engine Results | How to Optimize Search Engine Results | Optimize Search Engine Results

Any average American who opens a window by grasping the frame or a small handle and pushing it upward is dealing with a sash window. Children know all about sash windows even if they don’t know the name. In all likelihood the average child in America or even in England would know little about the origins of the sash window.

Most children are unaware of any connection at all between sashes and windows until they hear the famous poem that may or may not have been written by Clement Clarke Moore. It might have been written by Henry Livingston Jr. Most people don’t care about the name of the author as much as they care about the names of the reindeer.

The connection between windows and sashes comes in the line where the author describes how he flew to the window and “tore open the shutters and threw up the sash”. A child unfamiliar with architectural terminology could become confused at this point and wonder why the narrator is vomiting the belt from his bathrobe.

An adult seriously concerned about the child’s education and emotional well-being will stop laughing long enough to explain what a sash window is. This kind, mature person will explain that a window sash is the wooden frame around the pane of glass that moves up and down.

A bright child is likely to be so fascinated by this information that he or she will begin delving into history and learn about Robert Hooke who is credited with inventing the sash window in the 17th Century. He might have, although some people say he only got credit for it because Sir Isaac Newton was getting credit for all the really exciting discoveries and inventions. No one patented the invention and Newton and Hooke were probably much more interested in who got credit for gravity and things like that.

Actually there had been windows that slide up and down in use for a long time, probably since the 1200s. But windows didn’t have glass in them in those days so a sash window would have been more of a sliding wood panel. You could open it to let in light and bugs and air but it wouldn’t keep anything out unless it was closed.

The modern sash window came into being when the vertical sliding panel was combined with glass window panes and pulleys and weights to counterbalance the weight of the wood and glass so that the window could be opened by someone who did not possess super strength. One of the best places to explore the origins of the sash window is Ham House in England. It’s a National Trust Estate that is open to visitors and has sash windows that were installed in 1670.

A Look At The Environmental Benefits Of Sash Window Restoration For Period Properties

Wednesday, July 28th, 2010

A lot of the latest window and door products are geared towards thermal efficiency in an effort to appeal to environmentally conscious consumers. Nevertheless, deciding to recondition original sash windows as an alternative to buying new ones can be better for the environment. The environmental benefits of sash window restoration are noteworthy.

Some home owners choose to replace wood sash windows with PVC types. Yet, restoring wood frames instead of supporting the production of new PVC is a more environmentally friendly choice.

Even if you buy new wood frames instead of PVC, there are disadvantages from an environmental stance. Deforestation is a big problem so it is better to reuse old wood. In addition, old wooden window frames are often longer lasting and better quality than those made from new wood.

There are also aesthetic reasons for preserving old sash windows. Wood can be considered more attractive and traditional-looking than PVC. Original sash windows won’t clash with the architecture of an old house, unlike some new window designs.

Many home owners are worried about conserving heat. It’s good to know that a number of alterations can be made to old sash windows to address this issue. For example, extra glazing can help to sound proof and insulate a room. Resealing the window is another way to cut down on draft problems.

The sash window design provides great ventilation. During the summer, you can open the sashes on the bottom and the top to help your house stay cool. That way, warm air can escape through the top of the window. Meanwhile, cool air is let into the house through the bottom sash. This system can mean you won’t need to use air conditioning or a fan. The design of sash windows helps them to be an environmentally friendly choice.

A major benefit of sash windows can best be described as allowing the house to breathe. This is important for maintaining a comfortable and healthy atmosphere inside. In contrast, some modern window replacements are virtually airtight. This can lead to problems with ventilation and the build up of condensation. Good ventilation is important for health. It also prevents excess moisture from accumulating. A damp problem in plaster and woodwork can be very damaging and expensive.

These are just a few of the environmental benefits of sash window restoration. It’s also worth noting that restoring old windows is often less expensive than installing new ones. An Internet search will help you to locate sash window restoration companies near you. A number of these companies will give you a quotation at no cost.

Sash window restoration London area offers assistance to those who want to save on energy costs. Instead of discarding or replacing sash windows, you can restore them instead.

What Form Of Insurance Policy Should A Sash Window Restoration Firm Have

Monday, June 28th, 2010

Optimize Search Engine Results | How to Optimize Search Engine Results | Optimize Search Engine Results

If you are starting a window restoration business then one thing you should know is what type of insurance policy should a sash window restoration company have. You may be the only employee in the company at first but still you require an insurance. This can protect you for any unforeseen liabilities that will arise.

Basically, there are four insurance coverages. These are: workers salaries, vehicle insurance, property or casualty insurance and general liability which is an umbrella insurance policy.

Worker compensation insures the salaries lost if an employee gets injured while working. This also pays for the medical expenses incurred by injured employee. This coverage is legally required in 50 states. There are two parts to the coverage. First pays for the medical bills and salaries of the injured employee. Second is the employer liability if injured employee or spouse files a lawsuit against the firm. Third is an optional aspect of workers compensation insurance which insures practices liability like sexual harassment cases.

Business owners may not be covered by the policy. You should see if your insurance pays for you. If not, you will not receive money in the event you get injured while working.

If you want to pay lesser premium then maintain an excellent safety record in your company. Stick to the guidelines delineated by Occupational Health and Safety Administration for safety. Job classifications are important also. The level of risk for each position will determine the insurance coverage ratings.

Another method of reducing premium payments is to make sure that the jobs are classified correctly. Insurance agencies provides for different ratings to jobs depending on the degree of risk of injury.

General liability insurance pays for accidents and injuries that occur while in the place of work. For a window sash firm the workplace could extend to the homes of thousands of their clients. General liability will pay for damages while installing the windows. You may opt for additional policies in your coverage. Take for instance, a policy on errors and omissions. The insurance pays for any omission problems while doing work that may arise.

Auto Insurance. This is important if you have company transport. To pay less on the premiums, you have to increase the different deductions. But make sure that the deductibles are paid in case accidents happen.

Property/Casualty. An all-risks coverage is necessary for business. This type of coverage can pay for all kinds of dangers such as snowstorm, bombings or fire. These are the factors to take into consideration when deciding what type of insurance policy should a sash window restoration company have.

A sash window renovation service performs a necessary function for the community. It is still important as a sash window restoration business owner to obtain insurance coverage to protect the company from financial loss.

An Overview Of Answers For The Plague Of Plastic Windows In London

Sunday, May 9th, 2010

Optimize Search Engine Results | How to Optimize Search Engine Results | Optimize Search Engine Results

The plague of plastic windows in London seems to be more of a scourge on the beauty of once-proud manses of eras gone by. Anyone can see that cheap plastic windows do NOT fit in with the majestic, and occasionally creepy, gargoyles that flourish on the rooftops of many Victorian buildings.

Here is a short list of just a few reasons cheap plastic is making more of an appearance in London these days - along with some alternatives for mixing affordability with original quality:

Although it definitely helped their sales, double glazing manufacturing companies aren’t lying when they tell consumers that the new plastic product is much cheaper to install and replace when needed, especially when compared to the only other option, which is spending through the nose to fix the original antique wooden ones.

Conservationists have tried to remind consumers that it’s less of a cost - in the long run - to have the antique windows repaired because the lesser-quality plastic ones need to be replaced more often - which adds up to significant cash going out. However, many homeowners choose to opt for them anyway because of the affordability, and throw caution to the wind on future replacements.

Furthermore, environmentalists have jumped on board, claiming that the new double glazed windows help keep the heat in the house during the cold winter months, therefore preventing the escape and release of carbon emissions into the air - which adds even more pollution to the environment.

However, historical societies, who are lobbying for the return of antique wood sashes to the homes, have named several cost-effective alternatives for weather and emission proofing that work just like double glazing - and can be used in conjunction with the original frames. One way is to draught-strip the edges of the frames with brush stripping to create a seal. And for those who say that’s too expensive - tubes of rubber or silicone are available at a very affordable price, and do the same thing.

Putting shutters over the windows, or even draping them with heavy curtains, works quite well as long as the owner remembers to keep the windows shut. And for those who insist on it, there’s even a secondary glazing that is cost-effective, has the same benefits of the double glazing, and also works in harmony with the antique wooden frames.

So while there are two different sides to the plague of plastic windows in London saga that continues on, and each side disagrees with the other - it’s most likely that the one point on which they do concur, is the importance of finding a solution that is low-cost, harmless to the environment, AND allows the beautiful Victorian buildings to keep their antique wooden sash windows.

These are known as the primary carbon footprint and also include a measure of how energy efficient your home is. That is, does it have insulation in the loft and wall spaces etc.

Next, it asks questions about your indirect carbon usage. This is your secondary footprint and involves things such as where your produce comes from. Do you buy sugar produced in your own country or shipped in from far away for example?

Double glazing is an excellent way to trim down your carbon footprint. They act as insulators for your home. They trap air between two panes of glass - a sort of mini greenhouse effect, and keep your house warmer.
