uPVC Windows Guide

Time and fashion move on in all things and this is true of window production also.  When window replacement in favour of double glazing windows became the fashion nigh on 40 years ago, the aluminum window was the most popular choice to replace the humble timber window, which had been doing its job from time immemorial.

In a relatively short space of time aluminum windows moved from being a relatively new product on the market to holding well over 50% of market share.  This was due to several factors.  Aluminum did not cost as much to produce as timber, it could be made in suitable lengths for most window sizes, and it was and is a very strong product that would last for a long time and needed little attention.

However as stars rise they can also fall and once uPVC windows and other uPVC products such as doors and uPVC cladding came onto the market strongly about 20 years ago, the fall in sales of aluminum window units has been steady and inexorable.

So what makes uPVC windows and doors so good that they are able to dominate the replacement window market ahead of a window that was hailed as a breakthrough in window production just a few years earlier?

One of the main problems that aluminum had at that time was an unfortunate ability to conduct cold and heat.  This may be an admirable talent in other products, however it is not something that window manufacturers or homeowners yearn for in their windows.  In more recent times the manufacturers of aluminum windows were able to tackle this problem by fitting thermal breaks into aluminum window frames and this helped to reduce the conductivity of these windows, but by this time uPVC house windows had gained a strong foothold.

The main issue with windows made from aluminum is that they seem to be able to out-perform timber windows on a variety of fronts, but they are either only able to equal the performance of uPVC double glazed windows or else the under-perform slightly against them.

uPVC window prices and the cost of aluminium windows are pretty equal when it comes to cost competitiveness for example, whereas windows made from both of these products can be produced cheaper than timber windows.

Aluminum and uPVC windows are very easy to maintain during their lifetimes.  Timber needs reasonably frequent re-painting or it may suffer from weather related deterioration.

However there is one factor that keeps aluminium in peoples consciousness when it comes to window installation and that is security.  Aluminum window frames are very strong, stronger than uPVC frames and this makes aluminium storm windows an excellent option for strong adverse weather conditions, and aluminium windows in general are a popular choice when security of the home is of paramount importance.

In these present times of homeowners both being away from the house during the day due to work commitments, this can be a compelling reason not to discard totally from your mind aluminum replacement windows.

In the same way that homeowners weigh up various factors, such as price competitiveness, attractiveness, ease of use, maintenance, durability and other factors with regard to any product for the home, the same has to be done when you are trying to decide between a timber, uPVC or an aluminum window.  Window frames made from alumimum may not be ‘top of the pops’ anymore, but it is perhaps too soon to consider writing them off.

There is no doubt that uPVC windows are now the most popular type of window above all other windows on the market today.  If that is a fact, then the question has to be asked why it is so.  In this article we will outline five reasons why homeowners are choosing uPVC double glazing above a timber or aluminum window or any other window type that is available on the market.  By the time you have finished this market, we hope that you will have an understanding of why double glazed uPVC windows are leading the world in window production.

1. Energy efficiency:  Nowadays the sight of a monthly fuel bill arriving through your mailbox is enough to cause tremors of fear in many people.  Fuel cost are rising constantly and on top of that there is continual talk of ‘polluter paying principles’ and ‘carbon taxes’.  It is very important for all of us to have houses that are as energy efficient as possible.  Older type wooden window frames simply do not have the proper ‘U-factor’ capacity to seal your residence properly.  The ‘U-factor’ is a measurement of the rate of transfer of heat through a material.  Quality double glazed uPVC or vinyl windows with a low ‘U-factor’ are highly energy efficient and these windows will assist you greatly in slashing fuel costs in your home.

2. Range of styles and colours available:  There used to be a standard joke regarding a PVC window that it was available in two colours – white or white!  While that joke may have had a certain ring of truth to it about ten years or so ago, things have changed dramatically in the production of these products since.  They are now freely available from most established window manufacturers and double glazing window installers in a large variety of styles and colours.  One of the most popular choices by homeowners presently are the wood-grain finish windows, which can look like light or dark timbers and are very hard to distinguish from real timber at any distance.

3. Home Security:  Not that long ago security in the home was not top of a homeowners agenda – in fact many people were quite comfortable with leaving keys in their doors at night, or leaving their front door unlocked.  All of this has changed unfortunately and homeowners require now that their doors and windows are secure at night- time and when they are away from their property. uPVC double glazing doors are very strong and durable and quality windows have excellent uPVC window handles and window locks built into the framework of the window unit, which gives them added strength.  In addition to this double glazing is much more difficult to break through than older windows with single glazing, so most homeowners are going for the more secure option.

4. Window maintenance: One of the main advantages of uPVC as a material is that it requires very little maintenance from the time it is installed in your home as a window frame, until the time that you decide to change your windows again.  A uPVC double glazing window requires cleaning, as any window does, but other than that there is very little maintenance needs to be carried out.  On the other hand, if you want timber windows to last, they need regular re-painting and maintenance and even this may not be enough to stop them warping and leaking if you are living in a damp climate.

5. Re-sale value of your property:  Many homeowners are not thinking about selling their property when they install their uPVC windows.  However there may come a time when for work reasons you want to change location, or maybe you simply will want to downsize, and this is when you will be glad if your have installed uPVC double glazing windows.  Over seventy five percent of people questioned in a survey, when asked to rate the important points they looked for when they were purchasing or renting a home, put the fact of the home having uPVC windows as one of the main factors.  Having uPVC double glazed windows installed in your home will help you to sell or rent it and will help you to obtain a better price.

These are five of the top reasons why homeowners are continuing to make the change to uPVC double glazing windows.  Some homeowners who have construction or home improvement consider the options of fitting cheap uPVC windows themselves.  These windows are not cheap in the sense that they are of inferior quality, but if you are willing to install DIY double glazing in you can make considerable savings.  So if you are considering changing your windows, or if you are in the process of planning or building a new residence, get a double glazing quote and weigh up the uPVC double glazing cost against the many benefits that these windows could bring to you and your home.

This site is all about uPVC double glazed windows and their advantages.  However there are also disadvantages to a uPVC window in the same way that there are disadvantages to a timber or an aluminum window.  To understand what windows are all about and where a uPVC window fits into the window family, we need to look at the different types of house windows, their description and their different uses, apart from the obvious.  uPVC windows can and have been constructed in all of the forms below.  The following is not an exhaustive list of different windows, and is open to correction from anybody, but we have given it our best attempt.

Fixed windows: Pretty much as they describe themselves – they do not open at any time.  A fixed house window ideal where ventilation is not an issue, but where security is.

Jalousie Windows: These windows are constructed of metal clips and glass slats. These slats can be opened and closed. They are excellent for ventilation and light and due to their shape can be used in places that regular windows would not work as well. Jalousie windows however are not airtight and cannot be made airtight so they are impossible to seal.

Casement Windows: Window sashes opening on hinges that are generally (but not necessarily) attached to the upright side of its frame.  These windows open outwards as against sash windows, which slide up and down.  Casement windows are better in situations that are harder to reach as sashes can be difficult to open unless you are positioned properly.

Gliding Windows: Gliding windows for houses are windows that slide laterally rather than open outwards.  As they do not open outwards, they do not create an obstruction in an area of limited space.  However they can be more difficult to seal with regard to insulation than other windows.

Sliding Windows: Similar to gliding windows and with the same advantages.

Awning Windows: These are window frames that have one or more sashes hinged at the top and swinging outward.  These windows are specially designed for the purpose of providing light and usually can be opened by swinging out the sash.  They allow in a lot of light and air when they are positioned properly.  They are also to be considered when privacy is to be desired.

Palladian Windows: These are windows in the form of a round-headed archway, containing a single double-hung window, joined on either side by a double hung narrow window.

French Casement Window.

Picture Windows: These are large windows, which dominate the room, and which often are designed to present an attractive view.  They are an excellent light source but could be expensive to repair if broken.  Picture windows do not open, so can not be depended upon where ventilation is a requirement.

Windowscapes: ‘Windowscape’ is used to describe an entire wall made of windows.  The views are fantastic and so obviously, is the price.

Single Hung Windows: Single hung windows open by sliding up and down like a sash window, but with the top half being fixed.

Double Hung Window: A double hung window is a window that the top portion can be opened while the bottom remains closed – They are chosen for their style and excellent ventilation ability. Also they are popular for safety reasons, for example in children’s bedrooms, because they allow in adequate ventilation, while helping to prevent any accidents.  They are also popular in kitchens for ventilation reasons.

Hopper Windows: These are casement windows for houses with a sash hinged at the bottom.  Hopper windows open inward and are excellent for ventilation.  These windows are usually used in basements.  Can be difficult to work in with curtains and blinds due to the fact that they open inwards.

Rotating Windows: These are house windows that have a centre pivot that enables them to open from either side and top or bottom. One of the main advantages of rotating windows is ease of cleaning.

Bay Windows: Bay windows are contained in an alcove of a room and these windows have glazing to 3 sides so they can catch the light from some angle, during a most of the daylight hours.  They have a style that adds to any residence and as well as being able to receive sunlight from many directions, they also have excellent views. They are most useful in the living areas of a home where views can be most appreciated.

Bow windows: They are similar to bay windows but with less radical angles.

Oriel Windows: Oriel windows are also similar to bay windows, but they are supported by brackets underneath and as a rule they are much smaller than bays.

As I have said, this is not a complete list of all types of house windows, but it will assist you in considering the best option open to you when you are designing a residence, or thinking about replacement house windows for your home, attempting to compare house window prices, or trying to decide between aluminum timber or uPVC windows.

Window units with wooden window frames have obviously been the choice for many decades and even centuries.  In recent years uPVC doors and windows have made an incredible impact in the window market, as these windows have many advantages, including ease of maintenance.

Now many manufacturers such as Marvin Windows, Anderson Windows and Senator Windows and Munster Joinery, to name but a few, are huge players in the business markets and produce many different types and styles of windows, that home owners can install themselves if they wish.

However, as many environmental questions hang over the issue of uPVC production, there are disadvantages to uPVC windows and as the timber window manufacturers have started a spirited fightback,  the pros and cons of each are being debated with renewed vigour.

• With regard to the life span of the products, both camps make claims for victory, with the uPVC window suppliers claiming that 25 years is a good life span with minimum maintenance and the manufacturers of timber windows saying that given the improvement in timber protection products (not environmentally friendly by the way), that timber windows, with proper care and attention could have a much longer lifespan that their counterparts.
• The  wooden window frames fan club, The WWFC, ( just kidding!), claim that whereas a handyman can and will carry out repairs to a wooden  window frame, the same cannot be said for the complicated moulded and sealed system that is employed in the manufacture of uPVC windows.  If your uPVC window frame or locking system breaks, call the installer.  An added point to this is that in the event of a break in to your home, the damage that may be done to your uPVC window frame may be impossible to repair.
• It is a law of nature that all products deteoriate over a period of time.  In several years, when your timber windows lose their lustre, or when you get sick and tired of that fashionable pink colour you painted them, you need only grab your paint scraper and wirebrush and clean them down and repaint them.  With uPVC windows however, you cannot do this.  In fact, you can do very little, besides keep them clean.  Manufacturers of uPVC windows say exactly, and that is why so many of their customers are happy – there is little upkeep and maintenance involved, and little temptation to change the look.

• The Environment:  Timber is a renewable and a sustainable resource.  Here the uPVC camp are on to a loser, as uPVC is a non-natural resource which create toxic products during production and which cannot be easily disposed of.  The argument being put forward by those in favour of timber window installation is that to install a timber window frame is to help reduce your carbon footprint.
• Many Planning Authorities are raising question marks with regard to the over use of uPVC sash windows in older residential estates and in character buildings.  The manufacturers of uPVC windows say that they, in turn, have made huge inroads into providing a wide range of finishes to their product and that often quality made uPVC windows sashes are indistinguishable from timber sash windows for example.

In this article we have not even started to talk about the possible benefits or disadvantages to an aluminum window!  If you want to find out more about either uPVC, aluminum or wooden window frames and want to narrow down your search to a certain geographical location, then you can do an online search under the heading ‘wooden window frames U.K.’ or Ireland depending on which country you wish to get results from.

Over the recent years uPVC has become one of the most used products in the manufacture of all types and styles of windows and doors, by the large double-glazing manufacturing companies.  After weighing up the differences between timber and uPVC windows, if you do decide on uPVC, you can purchase the windows and self-install uPVC windows yourself if you wish.  There are various cost and effectiveness reasons for this take over by the humble uPVC (un-plasticised Polyvinyl Chloride to give it it’s proper title), and we can outline some of these reasons in this article.  As well as benefits of uPVC windows, there are also disadvantages to uPVC windows but they are for another time.

• A uPVC window gives you very good insulation around the frame and employs the usage of thermal breaks. A uPVC window frame helps to keep cold out during the winter and conversely keeps the property cooler in the hotter months of the year, more important if you are living in an area which is affected by such extremes.  An obvious advantage to this, apart from your personal comfort, is the savings you can make in your heating and cooling bills by having uPVC window frames and glazing fitted.

• The excellent seals and aforementioned insulation present in uPVC windows means that dust particles and pollen are kept to a minimum in a building.  At high pollen times, hay fever sufferers will be thankful for the extra protection that they receive from this reduction of external allergens entering the home or office .
• During the life span of these windows, very little maintenance is required.  Of course they will look better with the odd wipe or wash to the window frames, but there should be no painting or weather-proofing required.
• Most uPVC window handles are durable and are of excellent quality and upvc windows have a very secure multi-point locking system, which gives a building more security than traditional types of window clasps such as old style, sash window locks for example. It is also very difficult to break through a uPVC frame.  If you are going to undertake security measures such as installing security cameras, or even fake security cameras and a house alarm, having double glazing and good quality multi-point locks in your windows certainly also helps.
• Cost is always a factor when installing such features as windows, doors, guttering, etc.  uPVC is well up there in the cost effectiveness stakes and this means that for a lot of people, cheap uPVC windows will be given serious consideration.  An alternative to both a timber and uPVC  type window with regard to cost effectiveness could be an aluminum window.
• Consumers worry about gas furnace prices when really they should be worried about the cost of their gas bills when their windows are not sealed properly and heat escapes through them.
• As well as keeping heat in and cold out, uPVC windows keep out a lot of sound also.  This is why they are often preferred in locations where sound suppression is of a high priority, for example, close to a motorway or busy road, train track, etc.
• Production of uPVC doors and windows has come a long way from the choices of colours that were available, namely white or white.  They are now available in many different colours, and in addition can be finished in wood lookalike styles with a wood-grain feel, they can also be manufactured with a different colour on the outside to the inside – in short, almost anything is possible!  you can put uPVC windows in most any building.  We have seen plenty of log home builders using these windows for their insulation properties.
• In many cases customers want a product that has the traditional look and style of wooden window frames but with modern operating technology, so products such such as uPVC windows, modern cast iron radiators other quality products and will always be in demand with consumers.

There are many advantages to uPVC windows, but the argument rages on as to whether uPVC windows or replacement  windows are environmentally friendly or not.  There are many differences between timber and uPVC windows and that is without even starting to throw the various advantages and disadvantages of an aluminum widow into the mix.

The process that is required to make PVCs is highly toxic and this in turn leads to toxic by-products.  On top of this, the point is made that the biggest problem with regard to uPVC windows and doors is their disposal at the end of their useful life – which seems to range between 10 and 30 years.  Some say that PVC is very easy to recycle but others counter by pointing out that in practise very few PVC windows are recycled because of the difficulty in separating the component parts.  Neither can it be incinerated because of it’s composition.

uPVC windows discolour !!  Some go yellow and while this is bad enough, others go a sort of  pink!  There are various reasons put forward for this discolouring problem, but without going into too much unnecessary detail as to the cause, the remedies are few.  You cannot paint PVC  windows, and anyway,  isn’t the lack of need for painting one of the main reasons you wanted UPVC windows in the first place?

Very bad weather or severe extremes of weather can cause cracking, expanding or warping to your double glazing, PVC windows.

PVC windows are not that flexible in design or in execution – this can hamper the creative artist in you when you are designing your rooms!

uPVC windows are simply not as pleasant on the eye as traditional windows.  Again this is a claim that is hotly disputed by the PVC fanclub.  In many case the argument is dependant on the  type of building the windows are going into.  If they are being inserted into a new build, modern structure that allows for the wide, bulkier window frame that PVC windows by necessity provide, then they will look well.  However if you are putting them into your turn of the century (19th to the 20th century that is), attractive brick, terraced residence, maybe they won’t fit in quite so brilliantly.

Once you have fitted uPVC double glazing or triple glazing windows, whether you install them yourself or get an installer to do it, no matter what type and style of window you install, they cannot be easily taken apart if they are in need of repair.  By this we do not mean simply changing a pane of glass, rather more structural repairs.  This can make them more expensive to maintain, as against a traditional window, which a regular carpenter or handyman will have a go at.

So there you go – food for thought if you are thinking about dumping those timber windows on the woodpile and investing in some shiny, spanking new PVC ones.
