uPVC Windows Guide

Most everyone is aware of the substantial benefits that can be achieved when double glazing is installed into a home.  Not only does it increase the energy efficiency of the property, but in doing so, it automatically makes the home a more comfortable place to reside by making it warmer and less prone to draughts and sound pollution.  Unfortunately replacing your old windows is sometimes not as easy an option as one might suppose.  There may be physical pitfalls to replacing your old windows or possibly you are being quoted very high uPVC window prices that are simply too high.  If this is the case with your property, you could consider installing secondary double glazing as a reasonable alternative.

Firstly what is secondary glazing?  It is a window glazing unit that is placed directly over your existing window frame, thereby insulating your window unit and creating a pocket of air between the two sheets of glazing.

There are various reasons why this glazing may be preferable to installing replacement double glazed windows.  The main reason is selected would be that the homeowners are not allowed to change their existing windows to something such as uPVC windows, due to a planning restriction, which may have the home listed as a protected structure. Buildings are listed for a very good reason, in order to protect and preserve our architectural heritage.  However it can be very frustrating and uncomfortable for a family to have to live in a cold, energy inefficient home, all because they cannot install replacement sash windows or other types of replacement units to replace their windows that are allowing a lot of air leakage.

It is in cases such as these that secondary double glazing becomes appropriate as an insulation barrier inside the timber sash windows.  It is also considerable cheaper than replacing all of your window units and some people elect to carry out this glazing on some rooms of the home, that are in particular need of extra insulation.

If you are a home improvement enthusiast, DIY secondary double glazing is easier to carry out than replacing your windows.  You can purchase secondary double glazing kits from window suppliers and follow the detailed instruction in order to achieve the best results.

It should be said that by installing secondary glazing windows you will not have a sealed pocket of air between the two panes of glazing.  This is not as effective a method of insulation as proper double glazing windows by a long shot, but is a reasonable second option.  With this method you also have the advantage of being able to remover the secondary glazing, which allows you to maintain, clean and open your windows.

In the United Kingdom, secondary glazing can be very popular, as there are many buildings that have restrictions placed on them with regard to window replacement.  ‘Secondary double glazing UK’ is a popular search term on the internet and one which will help narrow down your search if you are looking for a supplier of this type of product.  If you have a particular type of window that you wish to get quoted for, why not search under ‘secondary double glazing sash windows’, ‘double glazing window installers ‘or some other term which will help put you in the right direction.

So you have weighed up between timber and uPVC windows and decided on the latter.  There are many advantages to uPVC and only few disadvantages to uPVC windows, but I would suggest that one difficulty with uPVC double glazing windows is self-installation.  DIY double glazing windows? Now I am as fond of a little DIY as the next person, and I don’t mind maintaining my windows, but when it come to installing uPVC windows into a residence, I call a professional.  It may not be that difficult, but I reckon that having paid quite a bit of money for these shiny frames that scratch easily and are not easily repaired if scratched, I don’t want to take too many chances with uPVC window repairs.  Call me gutless if you like and for the more brave-hearted amongst us that want to DIY double glazing units, here are some instructions to give you a flavour of what is involved in installing your own uPVC windows.

How you fix the window frame to the opening may depend on the type and style of window and whether the wall cavity is open or closed. There are 2 main ways to fix a window.  One way is to screw through the frame and into the wall and the other way is called lug fixing and involved attaching a lug to the window frame and this lug is then attached to a block in the interior wall.  The first way is popular when the cavity is closed and the second when it is open.

You may wish to fit the external cill at the same time, but many choose to fit the cill first and as a separate process.  If you are fitting the cill and the frame at the same time set the frame properly in the opening, making sure it is level and central. Likewise ensure that the cill is level and that both cill and window are then attached properly.  Before commencing glazing it is advisable to open all window frames to ensure that they have not become strained in the insertion process.  Remember to leave an expansion gap around the frame, uPVC windows can reach quite high temperatures in hot weather, so the ability to expand is important.

The next step is the insertion of the glazing into the frames.  I should have mentioned that the frames will be arriving without the glazing pre-inserted.  If you want to  the big trick with regard to glazing is ‘Toeing and Heeling’ a phrase used describe the bracing of the window in order to stop the window ‘dropping’ on the handle side in the future. You achieve this by pushing plastic packers into the gap between the glass and the frame, under the beading.  When you are happy that everything is positioned correctly, you can push the glazing beads into position and fit the wedge gasket internally.

When this has been completed to your satisfaction you are ready to finish the job.  Clean and tidy up as best you can before starting to silicone to the external gaps and the filler internally. Clean the glass thoroughly and stand back and enjoy the satisfaction of completing your first uPVC DIY double glazing windows installation.

Another , perhaps less difficukt option for you to consider is DIY secondary double glazing.  This involves installing an inner secondary pane of glass and does not involve the removal of the existing fraome or window units.

So if you want to investigate all of the uPVC window prices on the internet and in your local area, then weigh up the cost of installing these windows, you may find that if you install them yourself, you will end up with quality, but cheap uPVC windows.  Me – I’m calling a window installer.
