uPVC Windows

You can significantly improve your home’s energy efficiency by installing uPVC double glazing.

Over 20% of the heat in the average uninsulated home is lost through the windows. This can result in higher fuel bills and other unwanted side effects such as higher noise levels and condensation from the outdoors.

Why uPVC Double Glazing?

– Higher security compared to single glazing
– Reduces dampness in your home
– Reduce noise from outdoors
– Greater insulation properties

Benefits of uPVC Glazed Windows

Single glazed windows are extremely poor at providing any insulation. Cold air is transferred quite easily by the single glass panel which reduces the temperature indoors, and therefore requires a high amount of energy for a comfortable temperature to be maintained.

Modern windows are comprised of two sheets of glass with a layer of heavy inert gas or air separating them. This produces an insulating barrier that reduces outside noise and heat loss. When warm air is kept in your property it will be better insulated which results in lower energy bills and fewer draughts.

Double glazing helps to reduce damp inside the house through reducing condensation. The internal panel of a window unit’s glass being at a temperature that is closer to the room temperature reduces the internal air’s effect from reaching its dew point.

uPVC windows are much harder to break compared to single glazed ones. Therefore, they increase the home’s security as well as the outside environment.

Cost Considerations

The cost is going to vary based on a number of different factors including the material, style and size of the window you select.

The energy rating on the glass will also impact the cost. A-rated glass will typically cost 10% more.

Consider fitting costs and the fact that window prices might vary depending on the area that you live in.

The best way to determine what your new windows are going to cost is to get quotes from several different companies. This will not only provide you with price estimates, but also can help prevent you from over paying.

Costs of uPVC Windows

The following prices are based on the cost of uPVC casement windows (includes VAT) from several UK companies. Supply costs only, doesn’t include the fitting cost.

Size and Price

620 x 1050mm – £130.00
620 x 1200mm – £140.00
915 x 1050mm – £140.00
1200 x 1050mm – £175.00
1200 x 1200mm – £215.00
1780 x 1050mm – £275.00
1780 x 1200mm – £290.00

It’s important to get several no obligation quotes on your project. uPVC is usually considered to be an inexpensive solution when it comes to double glazed windows. However, some uPVC windows are less expensive in construction compared to others. If the uPVC is of inferior quality it can result in discolouration, leaking and distortion in a fairly short amount of time, so the least expensive solution is not always the best one.

What Can Drive up the Price of Windows?

Consider that certain added features may drive up window installation costs. Choose a basic white uPVC window can help to minimise your costs for a smaller budget.

Frame material

The price of different window frame materials can vary dramatically. For example, the cost of aluminum frame may be double what the price of uPVC is. You may want to weigh the pros and cons of different materials, since some might offer added energy saving benefits and have longer lifespans.

Window effect and colour

A uPVC frame that has an added wood grain effect or that is coloured will cost about 15-40% more compared to a standard white one. These frames do not typically add additional costs for installation.

Glass efficiency

Higher efficiency levels are offered by A rated windows. These windows are more expensive compared to standard B rated ones.. You will have the option of low emissivity (low-e), coatings added to the glass. This will drive up the cost but overall increase the energy performance (by as much as 40%).

Costs of double glazing maintenance

There is usually not a lot of maintenance needed with double glazed windows, especially in the beginning. Most of the time new windows will have a guarantee (usually 10 years) so that will protect you during that time frame.

Fogging is the major problem that homeowners encounter when it comes to double glazing, which is when condensation gets in between the panes of glass. The solution for this problem is usually to replace the glazed part of the windows. If it happens after the guarantee period is over, you will have to pay for replacement units.

Are there Grants Available?

There are no grants currently available in the UK. In the past, homeowners were able to obtain grant style loans via the Green Deal scheme, which covered double glazed window installation. Unfortunately, Green Deal funding was pulled in 2015.

Is Secondary Glazing a Good Alternative Option?

Secondary glazing is a less expensive but effective method. It’s usually comprised of a frame that contains a single glass panel that gets applied over an original single glazed unit. It is a less expensive method of achiever less loss of heat and may be a good option for listed building since planning permission is not required.
