Find the Most Competitive Prices in the UK
Have you considered double glazing when deciding to renovate your home? Not yet? Then it is time to start because now it is easier than ever before to compare prices and types of double glazed windows and doors with our comprehensive guide.
Double glazing is the process of glazing in which two panes of glass with space between them are put together in a window. Usually, the air between the panes is trapped, which creates a layer of insulation. Besides this, in order to ensure that there isn’t any moisture inside the double glazed units, a drying agent is added and, afterwards, the product is sealed.
Unfortunately, the double glazing grants are not available anymore even though the government’s Affordable Energy Initiative still recognise this technology as an insulation method for every residency. Grants can only be issued under Affordable Warmth Scheme, which gives priority to old properties in a stage of disrepair.
Despite this issue, the cost of double glazed windows and doors will gradually pay for itself because, in comparison with the single pane windows, double glazing mitigates heat loss and allows you to save around 11% of your heating bill. There are several variables to be taken into account when choosing a double glazed window or door that fits your budget. In the following research, GreenMatch provides price ranges of double glazing based on size, colour, and type of the window and door.

Compare Costs of Double Glazed Windows
Types of Double Glazing Windows
Casement windows are designed to be installed in large houses as they allow the maximum amount of light to penetrate the rooms. They open rather like doors and are usually hinged on one side. Due to design and glass patterns, the windows provide good air circulation and a unique aesthetic.
‘Tilt and turn’ windows have a dual hinge system allowing for more practical use, especially when cleaning. They suit perfectly big houses with small children because they offer maximum light exposure and security (they are tilted only a fraction to prevent children from opening them widely).
uPVC Sash Windows are manufactured from a number of smaller panels separated by some bars. They fit perfectly old properties that were built in Georgian times, which decreases the chances of being replaced. Unfortunately, it is costly to double glaze due to a limited number of natural uPVC Sash.
A bay window is available in three openings and constitutes of one main window and two smaller ones on either side. It is typically installed in modern houses to enhance the interior floor space. By having only three panels, it allows for a significant amount of light penetration. Meanwhile, the bow window usually has four to five openings in a curved structure. By having more glass panes, more light is allowed in, and due to its ability to be wrapped around the building corner, the bow window offers a unique two-sided view of the home.

Find the Best Windows and Frames
uPVC is the most popular type of frame because it is much cheaper and effective than timber. Besides that, there is a low chance of rot from moisture, which also makes it easier to clean and maintain.
However, not everybody likes uPVC material, so they tend to go for alternatives such as aluminium. The disadvantage is a higher price, but it can manage to maintain the old vintage style of your home—if that is what you are looking for. Overall, depending on the size of the windows and doors, the thickness can differ from 14 to 28 mm.
Importance of Argon Gas in Double Glazing
Argon is a non-toxic, colourless gas denser than pure air and is used to retain heat within a window. It lasts over twenty-five years and loses around 5% of its density, which means that it will last the entire lifetime of the double glazed window or door.
Xenon and Krypton are other alternatives to Argon that keep the heat inside even better, however, they are more costly and are typically used in triple glazed products. Moreover, the width between the panes should be greater in order to be effective; and this will influence the total costs as well.
Costs of Double Glazing Installation and Replacement
In terms of performance, double glazing is a more improved technology compared to single glazing; however, they are not always perfectly efficient. In cases where condensation materialises between the panes, this can cause cracks or chips that damage the window or the door.
When installing double glazed products, manufacturers usually offer a guarantee for twenty years, but the risk of damage still exists. There is no need to replace the whole installation because the measurements were taken and the frames remain intact; so, you can just replace the double glazing, which is cheaper.
Benefits of Using Double Glazing
Low Energy Bills
Double glazing has a direct affect on the cooling and heating system of the house as it can retain up to 87% of heat during winter and lose up to 40% heat in summer. High security: nowadays, double glazed doors and windows are manufactured with a multi-locking system, which, together with uPVC framing, helps in protecting your home against burglars.
Soundproof
The new technology is able to keep outside noise such as traffic noise, clubs, loud air conditioners, or barking dogs from penetrating your home. Therefore, you can enjoy the peace and quiet of your place by cutting out noise pollution.
More Comfort
Double glazing offers a unique feeling of comfort and cosiness by making your family gatherings more relaxed. The technology will keep the temperature stable both during summer and winter times so that you do not have to worry about constantly adjusting the thermostat.
Less Condensation
Condensation occurs when moist air and cold surfaces converge. It can damage walls, floors, carpets, and window frames. Double glazing can dismiss these problems thanks to special gas between panes, which helps to regulate the temperature.
Enhanced Value of the House
Installing double glazed windows and doors is a worthwhile investment because it brings value to your home. The benefits mentioned above are highly appreciated features in the market so the costs are justified.
Reduced Carbon Footprint
The actual worldwide challenges such as climate change and global warming cause serious concerns even today. In order to help mitigate the greenhouse effect, double glazing companies offer this technology as a method of reducing heat loss and household emissions.
Additional Costs That Can Occur
When choosing double glazed windows or doors that fit your home, several costs must be taken into consideration. For example, the style, colour, and size will be the main determinants. Then the energy efficiency comes into play depending on whether the window has an energy rating of A, B, or C.
In addition, you will be charged for the full technical expertise, extra security features, and full installation such as fixings or sealants. The list includes the price of glass (obscured, toughened or standard), external sill and handles. The final cost is the proper documentation and official registration as proof that your windows and doors are genuine double glazed products.
