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.

If you are purchasing new windows for your home, then once these window units are of good quality you should have little to fear with regard to their security.  Manufacturers are very conscious of the need to provide secure windows for their clients, so good windows will come adorned with window locks that should be up to the job of keeping intruders out of your home.

However life is not so simple if you have older types of windows installed in your home.  These could be period sash windows, old timber windows or even uPVC windows that were installed in less security conscious times.  If this is the case you may wish to review the security measures in your home and take some action.

Some homeowners with attractive antique windows for instance are reluctant to install new locking systems as they feel that this may ruin the character of the old units.  However with a bit of research it may well be possible to source locks from salvage yards that would make the windows more secure and yet would fit in with the character and style of the windows.

A difficulty that may arise is that a sash window lock located in a salvage yard may not have enough matching comrades so that you can fit all of your windows with the same lock.

If this is the case then it could be possible to locate good reproduction antique window locks that are much easier to locate in the quantities that you need and will probably work out more reasonable in price.

Window locks that have keys are the most secure type of standard lock.  However you do have the problem of either removing all of the keys from the windows when they are locked, otherwise a thief simply has to remove the glass in order to open the lock and you are back to where you started.   If you do remove all of the keys, it is important from the point of view of your own family’s safety that everyone is aware of the location of the keys, in case of an emergency.

Some homeowners prefer to purchase unobtrusive locks that can hardly be seen by anyone for aesthetic reasons.  Others take the viewpoint that the more visible the locks on their house windows are, the less likely it is that a potential intruder will try his luck.

Larger windows in a home may require more than one lock.  This is because of the pressure that can be put on a big window frame by exerting pressure from outside.  Another point to note is that very small windows can also be attractive to burglars and that these windows should not be overlooked when a homeowners are making inventories of window locks that are needed for their homes.

All windows in your home should be regularly inspected in order to gauge their security effectiveness.  Locks for uPVC windows are usually maintenance free and uPVC window handles are strong and not prone to giving trouble, but could be in need of some lubrication or perhaps there may be dust gathering in the lock that if not removed, could cause future jamming of the mechanism. If uPVC windows and doors are kept securely locked while you are away burglars will not normally try to force them, but will move on to easier targets.

A sash window lock can be very effective if installed properly, but if your sash windows are of the older style and are not very secure, you may wish to check out what types of updated window sash locks are on the market.
You can go online and view all types of locks for windows, compare prices to see what the advantages to different types of locks are.

Remember if window locks are going to be suitable for your home they have to be very effective at their job, they should look well and naturally they should be affordable.

• Double glazed windows work by placing two sheets of window glass or glazing in a framed unit with a gap of about 16mm between them.  This gap is sealed and either is a vacuum or there is a gas in the space, which effectively forms a barrier of insulation.  Triple glazing windows simply use three sheets of glazing instead of two.
• Not all double glazed windows are of the same quality.  A double glazing window comprises various components including frames, glazing seals and spacers.  The ability of the window to act as an efficient insulating unit will be dependant on the quality of each of the components.
• The combination of all of the window components will result in a window unit with a certain energy rating.  This is a measure of the quality of glazed windows in energy efficiency terms and is a very useful indicator for a buyer as to which windows are going to be better at doing their job.  Window ratings range from A-rated windows, which are the most energy efficient down to a much lower G-rating for lesser quality products.

Glazing windows possibly used to be a luxury that you enjoyed if you had the financial means to replace your existing windows.  Some homeowners installed secondary double glazing in the past and this is satill an option, but nt neccessarily a very effective one.  Given that the window glazing market has become much more competitively priced, that energy costs are rising, and that there are also DIY double glazing options open to homeowners if they are interested in DIY imporvements, many people give serious consideration to getting a double glazing quote and to having the best windows in their homes that they can afford.

In this article we will try to explain window glazing briefly and as un-scientifically as possible.  This can be a bit difficult when you start to talk about such things as ‘spacers’, ‘solar heat gain coefficients’, ‘low emissivity glass’ ‘secondary double glazing‘ and the many other terms that arise when we talk about double or triple glazed windows and doors.  However we will attempt to keep the terminology to a minimum and see if we can break down glazing for your windows into some basic and understandable points.

•    Multiple glazing is the assembly of various panes of glazing into one unit.  This could comprise two panes of glazing windows (double glazing), or three panes of window glass (triple glazing), and so on.  If we are talking about double glazing, then between the two sheets of glazing will be present a gas or a vacuum.  This gas or vacuum will be thermally efficient and will also have properties that assist in insulating your home against sound pollution.
•    The glass in a window unit is necessary, not surprisingly, in order to allow in light and allow the homeowner to see out of the property.  This may sound obvious, but in terms of insulating a building properly, it would actually make more sense to leave out windows altogether, because they are one of the highest contributors to heat loss in a building.  The thickness of each glazing sheet can range from a high of circa 10mm down to 3mm and are usually all of the same thickness.
•    Different and specialized types of glazing can be used when carrying out window glass replacement or installing new windows.  These can include low-emissivity glass, which has the ability to reflect radiation from the heat of the sun, tinted glass, which can help to reduce heat build up in the room and coated glass, which is a glass with a coating on it, which can improve the insulation of heat and noise in the home.
•    Spacers are the strip of metal or foam that you see between the panes of glass when you look at a double glazed window.  These spacers keep the panes of glazing apart and create a seal which traps the gas between the panes, or helps to seal and create the vacuum.  These spacers are used whether you are dealing with timber, aluminum or uPVC windows.
•    The manufacturers of double glazed house windows will most often carry a warranty for ten to about twenty years and this lifespan can be effected by various  factors, including whether the units are installed in the Northern or Southern Hemispheres. Typical reasons for homeowners changing window units or having to get them repaired would include seal failure and desiccant saturation. Desiccant is present in the spacers and its function is to remove the moisture from the sealed area that has formed during the manufacture of the window and also it stops moisture formation inside the gas or vacuum area.

These are some of the basic points that come to the fore when you are considering window glazing or replacement glass for your home.  Many homeowners face the choice of replacing their windows at some stage after they have exhausted the idea of carrying out window repairs to their existing window units.  Consider getting a double glazing quote for your home as double glazing windows are now the most popular choice with homeowners, as they provide excellent energy efficient units at a competitive price.

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.
