• uPVC windows are considered to be maintenance free. In broad terms this statement could be considered to be correct.  uPVC is a very strong and durable material that will need little maintenance in comparison to timber or aluminium as both of these windows will need to be painted over time in order to keep them weatherproof. Timber especially needs regular upgrading as water could damage the window unit. That is not to say that windows made from uPVC do not need regular cleaning as does any window and also moving parts such as hinges and locking mechanisms will always benefit from regular lubrication. However in the main uPVC windows do not need a lot of maintenance.

• uPVC frames, if they are of good quality are constructed using multi-chambers and also have thermal brakes set into the frames. This allows for excellent heat conservation in the home as the window frames working in conjunction with double or triple glazing help to stop heat escaping from the property and cold air entering.

• Windows made from uPVC help prevent noise pollution in the home. As many homes are situated in urban areas, traffic noise can be an irritant and the installation of quality replacement windows will often be the best solution towards having a more peaceful and quite home.

• Probably the main reason homeowners consider installing replacement windows is that they wish to cut down on their heating expenses.  Oil prices continue to rise and other heating fuels are becoming more expensive also. It is incumbent on all homeowners to try and make their properties as energy efficient as possible in order to avoid having to pay crippling fuel costs in the future and also possibly having to pay carbon taxes.

• The quality of the glazing used in any window is equally as important as the type of window frame that is installed. uPVC window frames used in conjunction with double or triple glazing means that you have an excellent window unit which will be durable, secure and highly energy efficient.

• In modern times security has become much more of an issue that it was in the past. The days of being able to leave a key in your door at night time or perhaps go away from your home for extended periods of time knowing that all would be well on your return have long gone. Window security is very important and quality uPVC windows have many of the answers. With advanced technology locks set into strengthened frames and giving the homeowner the ability to lock it individual window, windows made from uPVC are severe test for any potential intruder. Used in conjunction with a good home alarm system, the size of these windows installed in a home is usually enough to deter most thieves.

Finally it is important to note that as well is being energy efficient, secure and maintenance free, PVC windows will help to make your own look smart and attractive. Homeowners who have purchased these windows have rarely regretted their decision and even though they may have had to pay more initially for a quality product they have found that over the longer term they have accumulated great savings.

A vinyl window came into prominence several decades ago and since that time it has become the market leader worldwide in window sales.  They are popular with builders and individual homeowners alike for a variety of reasons.

Vinyl is a material that is used in double glazing window in order to make a hugely efficient window unit.  Double glazing comprises simply two sheets of glazing placed on top of each other and separated by a gap of circa 16mm.  Into this sealed space is placed a gas, which has excellent insulation properties.  This gives the windows their excellent insulation properties and makes them suitable for property owners that want to improve the thermal capacity of their homes.

Vinyl replacement windows are becoming very sought after by property owners, either for their own homes or for properties that they rent out.  With the fact that the price of heating oil for keeping homes warm in wintertime has risen sharply in recent years and is continuing to rise, most of these people realize that they have to make their homes more energy efficient, if they have not already done so.  So such actions as insulating attics, fitting external cladding and installing new vinyl windows instead of persisting with ineffectual window repairs are becoming more and more important.

In addition to being energy efficient, windows made from vinyl are very secure given that they have quality uPVC window handles fitted and multi point systems for locking in the framework.  They are also very easy to maintain and once they have been installed in a home they need never be re-painted.  This is in contrast to wooden windows that do need to be re-furbished every five years or so, depending on the prevailing weather conditions.

Timber windows that are not kept weather sealed will warp or rot over time.  This is not a problem that has to concern owners of properties, which have vinyl or PVC windows installed.

Depending on the window glass or glazing that is used in completing the window unit you can have windows that are specially adapted to particular conditions.  Glazing can be installed that improves sound suppression or glare from sunlight for example.  However just standard double glazing will help to block out normal sound pollution from most homes.

All in all a vinyl replacement window possesses a lot of positive attributes that will help make a home look more attractive, and will improve its energy efficiency, thereby saving the homeowner money.

The surprising aspect of all of this is that new vinyl windows are more competitive when it comes to price than most other types of windows.  In pricing comparisons between quality timber, aluminium and vinyl windows, the vinyl or uPVC window prices will always be very competitive.  So for quality windows at a price that is highly competitive, one would have to consider the option of windows made from vinyl.

This may be considered a tongue in cheek comment, but you might be surprised to learn that a large proportion of owners of old, character residences, refuse to replace old single glazed sash windows because they feel that there are inadequate alternatives on the market.

This misconception stems from when uPVC windows first came to the market strongly several decades ago.  These forerunners to the stylish windows that are marketed today were energy efficient, but very lacking in charm, minus the attractive sash windows locks that were evident on older windows and they came in a very limited range of styles and colors.

Owners of homes with character timber sash windows could not envisage replacing these beautiful, if energy inefficient windows with what were correctly considered rather ugly substitutes.

However all has changed in the intervening years and presently homeowners can find sash replacement windows that are made from many materials, the most popular being uPVC, timber and aluminium.  uPVC production technology, along with competitive uPVC window prices have advanced immeasurably since those early days and you can now get a uPVC double glazing sash window replacement in a range of sizes and styles and this window can be almost any color you choose, including a woodgrain style.

Interestingly, sash windows were traditionally found in period homes of the Georgian and Victorian variety, but their popularity has spread and they are often the choice of homeowners building new homes.  A sash window normally comprises two sashes which in turn can hold a single pane of glazing or perhaps six or nine smaller panes.  This collection of panes gives the windows and the home a character and look that is very popular.  In addition to this sash windows can be opened horizontally or vertically, which makes them flexible for use in different situations.

Homeowners who have resisted removing their old windows up to now and have insisted on carrying out window repairs in order to keep their old windows going are urged by energy conservation experts to revisit this subject.  Sash windows with underperforming window glass are notorious for allowing air leakage – that is allowing warm air to escape from a residence and cold external air to enter the home.

In bygone days this was not recognised as being as big a problem as it is today.  With the rising cost of heating fuel, homeowners now find it imperative that they take all measures possible to make their homes as energy efficient as possible.

Window sash replacement should be at the top of a homeowner’s list of projects, if he or she has old single glazed windows that are past their best.  Failure to act now will result in much higher future utility bills and the possibility of carbon taxes being implemented on property owners that have greater than average fuel usage.

There are huge amounts of research done on that amount of heat that is lost through poorly insulated windows in the home.  It pays to look at this research and to draw your own conclusions for it.  You can also look at the many options available to you as a homeowner, should you wish to get replacement sash windows for your home.  Simply search online by typing in phrases such as ‘ upvc sash windows ‘,  ‘replace sash window’ or a search term such as ‘replacement sash windows UK’, if you wish to narrow down your selection to geographically relevant results.

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.

As with any product on the market, there are always questions regarding the effectiveness of PVC as a product and its possible detrimental effects on the environment.  The following points will hopefully answer some of the queries that homeowners may have.

1.    Value: The PVC in a PVC window will outlast most of the materials in other windows and performs better than them.  When it comes therefore to getting value for money with uPVC window prices you are gaining on two fronts.  Because PVC windows are long lasting you will not have to change them for a long time and because they are very energy efficient your fuel bills will be lower over the lifetime of the windows and subsequently you will save money.
2.    Durability: About 90% of the applications PVC is used for are what would be called ‘long life’ applications.  This description aptly applies to PVC windows and doors and also to such products as uPVC cladding.  Some studies have shown that in relation to windows and their profiles, 40 years is the projected lifespan.  This is more than any manufacturers will give a warranty for – in fact most will only cover the windows for ten to twenty years – but that is to be expected.  uPVC windows and doors will survive well against corrosion, inclement, prolonged weather and impact damage.
3.    Good for the environment: Advanced production technology has meant that the resin manufacture for PVC now can save a lot of energy in the production of PVC and this means less greenhouse gases are being produced when manufacturing companies are producing PVC.
4.    Part-produced from renewable resources: About half of the ‘feedstock’ required to produce PVC comes from salt.  As salt is abundant and renewable resource, PVC doors and windows are being produced from ‘feedstock’ that can be renewed and the same cannot be said for some other commonly used building materials.
5.    Low maintenance: PVC or vinyl windows will require little or no maintenance throughout their lifespan.  This is a fact that is both beneficial to the homeowner and to the environment, as for example, other window types will require painting every few years, which will produce undesirable paint emissions.  Over the lifetime of a timber window for example, a homeowner could have to paint the window possibly a dozen times.  This can lead to a large accumulation of emissions and leftover paint, brushes and paint tins that all have to be disposed of.
6.    Recyclable: Improvements are being made every day worldwide with regard to recycling PVC.  There have been various initiatives introduced  by governments involving PVC manufacturers and the building industry and these initiatives have seen a dramatic rise in the ability of  PVC recycling.  Vinyl2010 is one such major voluntary initiative taken by the PVC industry, which looks at all parts of the PVC cycle, raises awareness of issues that need to be addressed within the industry and promotes action where necessary.
7.    Tested fire performance: Due to the fact that PVC has a chlorine base, it is an inherently flame retardant material, which does not easily catch fire.  For example the ignition temperature of PVC is circa 390 degrees celcius as against an ignition temperature of circa 250 degrees celcius for timber.
8.    High Standards of manufacture: Manufacturing PVC is a process that, like most processes of production, is strictly monitored to ensure that consumer health and welfare is protected.  Emissions that are produced during the production of PVC have to be monitored by the Environmental Protection Agencies of the various countries involved.
9.    Versatility: PVC is a highly versatile product that can be used to produce a PVC window of almost any style.  Whether a homeowner requires PVC sash windows,  casement windows or bay windows does not matter – all of these window types are easily manufactured and marketed at a competitive price.

3. The Advantage Of uPVC Sash Windows.

Wooden window frames have a natural beauty that is hard to be matched, even if manufacturers produce such products as woodgrain uPVC in an effort to persuade homeowners that they can have the best of both worlds.  Other advantages windows such as timber sash windows include the fact that they can have a much longer life than uPVC windows, are stronger in the framework and are more suited in buildings that are of interest architecturally.

However before you select any window you will want to consider their safety features and this also applies to a timber sash window.  There are various safety features that can be incorporated into double glazed timber sash windows and if you are interested in windows from a manufacturing company you can insist on these features being included.

Safety Window Stays: These ensure that a window that is opened accidently or if the person opening the window loses his grip, then the window will not open more than 45 degrees.  This is important as it helps prevent injury if a heavy window opens suddenly.

Window Cam Catches: In addition to sash window locks these help prevent a potential intruder from gaining access through the window.  Cam catches have been developed to a high degree and can be obtained for use by both persons who are left or right handed.  As a high percentage of home burglaries are perpetrated through accessible windows, it is important that these security features are considered for your sash timber windows.  These catches can be used on traditional sash windows or on timber sliding sash windows also.

Limit Stops: These are a very important safety feature and are especially appropriate for rooms that children may occupy unattended, such as their bedroom.  They comprise small and unobtrusive stops that will not allow the window to be opened more than a certain distance, perhaps 100mm.  It is important that not all of the windows in the home are set up in this manner as there has to be escape routes from the home in the event of an emergency.

If you are considering purchasing sash timber windows, ensure that the above safety and security features are built into the particular windows that you are interested in.  If they are not listed in the quotation discuss the matter with the manufacturers and see if they will include the omitted features.  However if you are looking at quality timber sash windows, then it would be surprising if these features are not already listed.

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.

With regard to materials in general, the resistance of that material to heat loss is called its R-value and this unit is suitable for measuring the insulation capacity of materials that make up walls and roofs for example.  However because windows have to allow light through them, they interact very differently with the exterior environment than solid objects such as walls do.  For this reason a better measurement of the energy efficiency of windows is what is called the U-factor, which measures the rate that heat is transferred through the window unit.  A simple guide to help you remember the difference between the R-value of a material and the U-factor, is that the higher the R-value the better the energy efficiency of the material and the lower the U-factor, the better its insulation properties.

There are other terms that may be quoted when you are researching for a suitable type of PVC window for your home.  These include:
•    Solar Heat Gain Coefficient: This is the term used to describe the measurement of how capable a product is at blocking the sun’s heat.  This value will be lower in a product that is good at blocking heat.
•    Air Leakage:  Most products allow a certain amount of air to be transmitted through them and with regard to windows and other objects that contain openings that need to be sealed when they are closed, this is certainly the case.  The lower the air leakage value, the better the window is at blocking air from getting through.  Presently there is no official requirement on manufacturers to display this measurement.
•    Visible Transmittance:  This calculates the ability of the product to let light through.  The higher this value is, the better the window is at letting light in.
•    Condensation Resistance:  This value calculates how good the product is at deterring the production of condensation and the greater the value the better the product is in this field.

When you are considering any or all of the above terms and their values, you should remember that the value should be relevant to the entire uPVC window unit and not simply the glazing.  Having uPVC or vinyl windows with excellent glazing is of little comfort if the frames and seals and other components are not up to the task.

One of the first points that we should make is that, similar to any product you can purchase, the cheapest make or model of PVC window is not necessarily the best value window you can get.  There is a huge range of uPVC or vinyl windows on the market, produced by different manufacturers and being produced in a variety of countries.  There is also a double glazing cost that you will have to pay to get good quality double glazing in your window units.

uPVC windows In A Period Residence.

In order to weigh up which is the best vinyl windows for you and your property, you should consider the following points:

•    The more research you do on the general subject of uPVC vinyl windows, the more you will be able to gauge the different levels of quality you are being offered.  Start your research by looking up websites and consider all of the different aspects of uPVC windows.
•    Pay attention to the reputation of the manufacturer of the windows you are interested in.  Does the manufacturing firm have a good name?  Look up the website of the firm and see if they have testimonials from satisfied customers on the site.
•    Consider the type of locking system you want for your windows.  Most quality uPVC double glazing windows have a multi-point locking system built into the frame.  If you are getting cheap uPVC windows that have an inferior locking system, you may wish to think again.
•    Again the quality and type of glazing being offered with the windows will always affect uPVC window prices.  You may have the option of purchasing such specific types of glazing as toughened glazing, security glazing and glazing which assists in suppressing sound.  These will add to the uPVC window prices overall.
•    The ‘R-value’ of the window unit is always important if you want your windows to be efficient with regard to heat retention.  The ‘R-value’ is a measure of the resistance of the window to heat loss and the higher the value the better the performance of the window.  Cheap uPVC windows that have a low ‘R-value’ may be a poor purchase in the long term as they may do little to help you lower your heating costs.
•    Consider the shipping costs of the windows you are purchasing, if you are dealing online.  Even cheap uPVC windows will suddenly become a lot more expensive if they have to be shipped to your home from a far-flung location.  When it comes to uPVC windows prices always keep a close eye on the bottom line price.
•    One way of ending up with good value or cheap uPVC windows is to install them yourself.  If you are reasonably competent at home improvement tasks, you might like to consider taking on the job of installing the windows when they arrive.  You will save a considerable amount of money, but beware, if you give up have to get in an installer half way through the job, it could end up costing you more.

As you can see from the above points, there are a lot of issues to be considered if you are looking for PVC-u windows and good value PVC window prices.  Take your time over your decision and remember, there is good value out there for these types of windows.  You just have to find it.
