How does double glazing work?

Double glazed windows are made up of two annealed laminated or tempered glass sheets. These sheets are separated by a spacer bar decorated cavity which allows air to be contained in it which provides insulation. To keep out extra moisture from the double glazing as well as efficiently trap heat, two seals are affixed to the glass- the primary and secondary seals.

What are the benefits of having a double glazed window installed?

Double glazing is designed to provide better insulation than traditional glazing. Properties lose heat through windows which is why the installation of energy-efficient double glazing is an effective method for this reducing energy bills whilst at the same time keeping your home quieter and warmer.

A double glazed window provides a barrier that reduces the amount of heat that is let out from your house into the open. This feature makes it possible for your house to remain warm during the winter months and keeps the heat outside during the hot summer months. The supreme insulation provided by double glazed windows makes it possible for you to enjoy cool summers and warmer winters.

What’s more, double glazing can last for 25+ years and over time it will save you lots of money in utility bills that you can save off which could offer a balance to the cost of a new window. Another important benefit for families is the extra security the double glazing gives. There is no price for the safety of your family as well as your possessions. In fact, insurance offers a discount on premiums if your home is fitted with double glazing.

Information about London


Will having double glazing installed increase the value of my property?

Double glazing provides more than just energy savings, it can also increase the value of your property. Double glazing is highly desirable and can be the difference between whether someone puts an offer in on your home or not.

What are the disadvantage of double glazing?

The space between the two panes of glass traps air and forms a layer of insulation. In the event that the seal isn't airtight, there will be condensation that appears between the panes which cannot be fixed easily. In addition, once double glazing is sealed, the pane cannot be pulled apart to be repaired. The entire window will have to be replaced. These are only really a problem if the glazing is not done with skill and attention to detail. At Elite Builders London, we make sure the job is done properly.

Can blown double glazing be fixed?

Yes, it is possible to repair cloudy or misty double glazing without changing the entire window as the glass can just be replaced. This job can be quickly done, all that is required is that we take out the glass units that you want to replace and get the window back to its original condition.

When the glass is heated up, it conducts heat quickly. With double glazing, there is a layer of gas or air between two panes of glass. The thin layer of air in double glazed windows serves as a heat insulator-that is it traps the heat and stops it from circulating and results in less conduction and reduces the overall loss of heat.

How long does double glazing last?

Typically on average, the lifespan of double glazing is about 20 years. Depending on use and where it is located, the window life can vary anywhere from 10 to 35 years.

Will I require planning permission to have double glazed windows installed?

You might have to get planning permission to fit in a new double glazed window in your maisonette or flat. However, you will usually not require permission to add internal secondary glazing. Another instance where you may not need planning permission is if the fitted window is very similar to the current one- that is a like-for-like replacement.

Take a simple mixture of four parts water with one-part vinegar in microfibre cloth and wipe the window clean in a circular motion. To get as much grime off the windows as possible, you will need to keep topping up your cloth with the mixture.

What is the best glass to use for double glazing?

The glass that is usually used for double glazed windows for optimal thermal insulation is low-E or low-emissivity glass. This type of glass is best for cold regions where a lot of heat control is needed indoors. This glass is more energy-efficient and leads to a reduction in heating bills.

Will double glazing make a difference for me?

A lot of benefits come from using double glazing over single glazed windows (one pane of glass no layer of glass in between). Double glazing means that your home is warmer and better insulated. This reduces draughts and also saves you energy heating bills. In addition, double glazing helps keep noise out so you do not hear as much noise from the outside.

Can I fit my new windows myself?

Being able to fit your window yourself will depend on your skill level and type of project. An insert replacement window means that the existing frame and trim are left in; this is a project that you may be able to handle. However, a full-frame replacement window requires a complete tear-out and replacement of the existing one, and it is best left to window professionals.

Can my window have double glazing in my home located in a conservation area?

It’s normally still possible to install double glazing.

Can double glazing reduce noise?

Double glazing is an excellent way to soundproof the ambient noise level in a room. These levels are typically below 65 dB. In some cases, extra soundproofing measures need to be put in place to ensure that the window can be adequately soundproofed.

What is double glazing U-value?

Double glazing U value, aka heat transfer coefficient, is used to measure the effectiveness of the various elements in buildings, such as insulators. It is a measure of the thermal resistance of the building. When the double glazing value is low, it means that the building's fabrics release heat slowly.

What is a casement window?

Casement windows are basic windows which feature hinges on one side. These hinges are affixed to the frame and used to open the window - all you have to do is swing it out. Traditionally, the hinges on a casement window are on the side but you can have them at the bottom or the top. If it’s at the bottom, the window swings open from the top to bottom and vice versa.

Can I have my existing window double glazed?

Yes, it is possible to have an existing window double glazed. All that is required is an extra layer of glazing attached at the top. Your existing window can also be double glazed with the fitting of a panel that separates the moulding and is secured on the inside of your existing window. Double glazing existing windows is easier for timber and aluminium windows. Most people do replace single glazing with a complete double glazing system though.

At the end of the day, your choice will depend on your budget, what you have in place now, and the windows that will look good on your property.

What is quadruple glazing?

Is secondary glazing and double glazing the same?
