Double-Glazed Windows and Doors– Everything They Have to Offer

Window panes are by no means made up of just one pane - even if it often looks that way to laymen. Instead, modern windows are sophisticated glass constructions which ensure that the heat stays in your house. This saves you energy, and as a direct consequence, a lot of money. Double-glazed windows and doors offer a good compromise between affordability and energy-saving potential and, therefore, are recommended in many cases. 

Why aren't single glaze windows better now?

Single glazing became obsolete due to excessive energy loss. Double glazing followed which, when sealed airtight, the cavity between the glass panes ensured less heat loss. Conventional windows with double glazing have a U-value of 2.6 - 2.8 W/m2K. Windows with only one pane are a thing of the past. Their heat transfer coefficient is far too bad. They also pose a major health risk if damaged because they shatter into thousands of pieces.

To increase the insulating effect and the thermal properties of the double glazing, the air in the cavity is replaced by inert gases in more advanced models. The best properties are obtained by introducing argon. This is colourless, non-flammable and non-reactive to external influences. 

As a result, it has numerous advantages.

What are the advantages of double glazing?

Cheaper than triple glazing

Double-glazed window installation is on average 15 to 20 per cent cheaper than equivalent triple-glazed windows.

It is important to note that the price is made up of various components. This includes, among other things, the frame material, the type of wood for wooden windows, fittings and handles, as well as optional safety, sound insulation and sun protection glazing.

Very suitable for conservatories

For many years, double glazing has established itself as the standard in conservatory construction, as the energy gain effects are high in winter. This allows you to use the conservatory as a complete living space at any time of the year.

High solar gains

The heat gain value indicates how well a window allows solar energy to pass into the interior. Normal windows with double glazing and a U-value of 1.1 usually have a g-value of 0.6.

This means that 60 per cent of the incident solar heat enters the room through the window. In winter, you can use solar heat generation to heat your living space.

The size of the windows is also relevant: they should be as large and high as possible. The window lets a lot of light and solar heat into the room.

Noise protection optimization is possible

If there is a lot of noise, you should think about additional sound insulation. Soundproof windows have thicker, more firmly glued panes, which can be divided into 6 soundproofing classes according to noise insulation. These can reduce the penetrating noise by up to 50 decibels.

Safety glass possible

Laminated safety glass is another option. Glass panes are bonded with an elastic, tear-resistant high-polymer film between the individual layers. If the pane breaks, the pieces of glass will stick to the film. This not only leads to a reduction in the risk of cuts or stab injuries but also increases burglary protection at the same time.

Self-cleaning system possible

Further optimizations, such as a self-cleaning system, are also possible. The coating on this glass actively breaks down organic contaminants such as dust, resin or bird droppings. In addition, the pane has a kind of lotus effect, so that the rainwater does not collect in drops on the pane, but is distributed over the entire surface.

To Conclude

Double-glazed windows and doors represent an important step in the development of window glazing. There are several things to consider when choosing new windows. Not only the quality and thermal insulation of the glass but also the insulation of your rooms must be right. Hence, always go for windows and doors that keep your homes lively.
