uPVC Windows Guide

Given the high price of fuel and the expectations that this mean-price is going to climb even higher over the coming months and years, it is important that we consider any and all ways to cut down fuel consumption in our homes.  By installing uPVC windows, a homeowner has the opportunity to obtain an energy efficient uPVC double glazing window unit that will improve the thermal capacity of the home and cut down on fuel consumption.  There is undoubtedly a double glazing cost that has to be taken into account and as there are many different types of these windows on the market, it is important to purchase a quality product as cheap uPVC windows do not neccessarily make the best windows for your home.  In order to do that and t0 be able to decide which uPVC windows to purchase, it helps to understand what is meant by window insulation, what units are used to measure window efficiency and what symbols to look out for on quality windows.

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.

When you first install uPVC windows, you reckon that they will be there for ever. However time passes and certain parts of your uPVC windows and doors begin to show sign of wear – uPVC window handles, seals, damaged frames, etc – there are many reasons why you may decide to change your windows.  However with some proper research into handles for windows you may find that you can get very good quality replacements which will mean you may be able to put off replacing your windows for a bit longer.

Wear and tear may not be the only reason that you want rid of your old window handles or even your uPVC door handles.  Up to date design has meant that newer style of handles are of a more ergonomic design and more functional, but the older types of handles have can cause a variety of problems.  They may not be attractive to look at, can be awkward to use and even not very hygienic (older models tend to have a lot of angles and nooks which collect bacteria).

In addition to this they can be a risk to the security of the home, as homeowners invariably lose the keys for the handle locks.  This can also cause a safety risk for the inhabitants if windows are kept locked and there is an emergency in the home.  another security measure homeowners employ in their homes is the installation of security window screens and these also have to be easily removed from the inside.

If you have tired of your uPVC window handles, if they are damaged, or if you simply want to upgrade the security and safety measures in your home, you can consider getting new handles for your existing uPVC windows.  If you wish to do this yourself you will need to source compatible handles and this can be tricky enough to do.  There are a huge range of these handles on the market and many have different characteristics.

Types of handles may fall into different categories such as Espag uPVC window handles, Cockspur handles and Tilt n Turn handles.  Firstly you should identify the manufacturer of the locking mechanism by looking at the ‘lock strip’ (which you can see when the door or window is open).

When you have discovered the make and the model of your handles and locks and contact the manufacturer who will be only to happy to supply you with updated and much more attractive versions of your existing handles.

Many homeowners put up with their existing window handles, mainly perhaps because they do not realize that they can change them.  Major uPVC manufacturers are reporting that they are now replacing more first generation uPVC windows than those that are made of aluminum or wood.

In many cases this is not because the windows are no longer able to operate, but because some parts of the unit, such as the handles, have ceased to function properly.  So it does pay to source replacement uPVC window handles and to get someone to fit them for you, (which is not an impossible task for you to carry out yourself if you have a mind to).

By installing new uPVC window handles you could be giving your self a few more years of grace, before you have to get down to the business of replacing your uPVC windows.
