When it comes to building a new home or improving an old one, few factors are as important as the windows. Windows are among the key components of your home being responsible for allowing in light and air and for keeping out noise, intruders and the elements.

If you are thinking about building a new home or it's time for you to replace your windows, you have a number of choices for materials. Wood and aluminium are the traditional materials for windows but choosing uPVC windows offers a lot of advantages. So much so that it's no surprise that PVCu is by far the most popular material for windows and doors today. Here are some great reasons why you should choose uPVC windows for your home.

First, let's look at what uPVC is. The word stands for unplasticized Polyvinyl Chloride. Known in the United States as vinyl or vinyl siding, uPVC is a low maintenance thermoplastic. It's also known as rigid PVC.

One of its main qualities when it comes to windows is that uPVC is extremely weather resistant. It doesn't contract or expand under in the heat and it's also resistant to ultraviolet rays. This means it won't crack or decolourise in sunlight. It won't peel as it's not painted. Nor does it warp. It's also resistant to saltwater, which is important if you live near the sea. All this means that uPVC is extremely long lasting. If you install uPVC windows, you should get 30-40 years use out of them.

The next major quality of uPVC is that of thermal and acoustic insulation. This means it keeps in the heat in winter, and keeps in the cool in the summer. And it keeps out the draughts and noise all the time. This can be enhanced through the use of double glazing.

When it comes to glazing, you can usually get the option of internal or externally glazed windows. Internally beaded windows are held to be more secure and resistant to forced entry.

Triple-chambered designs, coupled with superior draught-proofing saves energy, translate into lower heating bills and ensures a comfortable environment all year round.

Most PVCu window systems are multi-walled reinforced internally with either aluminium or galvanised Steel box section. Wall thickness tends to be around 3 - 3.5 mm - the thicker the wall, the stronger the section.

uPVC also offers greater safety and security. For one thing, uPVC is self-extinguishing. In case of a fire, it will stop burning by itself. To keep out burglars, be sure to order windows that are fully compatible with the most secure locking mechanisms on the market. This will ensure maximum protection against intruders.

The other great thing about uPVC windows and doors is that they're easy to maintain and keep clean. uPVC windows do not rot, peel, flake, corrode or blister, and this means little or no maintenance. You just have to clean the interior and exterior surfaces from time to time with normal household soap and water.

If all this wasn’t enough, uPVC usually works out cheaper than either wood or aluminium. And bear in mind that installing new windows will enhance the value of your home.

While white is the standard colour for uPVC windows, you'll be pleased to know that you can get them in a range of styles including mahogany, cherry oak wood grain, rosewood and golden oak.

If you're worried that your new uPVC windows will change the look of your home, this needn't be a problem. You can get sash windows made from uPVC that look just like your old ones. In fact, all types of window are available in uPVC including standard casements, vertical sliding windows and reversible windows.

To top it all, uPVC windows are environmentally friendly. The material is 100% recyclable, it requires minimal energy for manufacture, and it saves on electricity costs and air conditioner usage.

If you planning a new home, or thinking about replacing your windows, take a look at uPVC. You'll be getting a host of advantages and saving money in the bargain. Designs vary from company to company so it's best to visit some online retailers and check their catalogues.
