Choosing windows for a home or office is a responsible task, which directly affects the comfort, warmth and silence in the room. The heart of any modern window is a double-glazed unit. It is he who determines how effectively the structure will protect against cold, noise and prying eyes. In this article, we will analyze in detail what a double-glazed unit is, what it consists of, what types there are and, most importantly, how to make the right choice without overpaying. We will also look at how the price of a double-glazed unit per square meter is formed, because this is one of the key factors when buying.
Many people mistakenly believe that a window is just a frame with glass. In fact, a modern double—glazed unit is a complex engineering structure consisting of two or more panes hermetically connected to each other. A chamber (or several chambers) is formed between the glasses, filled with dried air or inert gas. It is these chambers that provide the main properties of the window: heat and sound insulation. Understanding the basic principles of a double-glazed unit will help you to choose it consciously and save on heating and air conditioning in the future.
Double-glazed unit design: we take it apart in detail
In order not to make a mistake with the choice, you need to understand what a double-glazed unit consists of. Basic elements:
- Glass. They can be of different thicknesses (usually 4 mm, but sometimes 5 and 6 mm) and with different coatings (energy-saving, sun protection, shock-resistant).
- The remote frame. This is a hollow aluminum or plastic profile that separates the glass and sets the width of the camera. Inside the frame there is a desiccant (silica gel), which absorbs moisture and prevents the glass from fogging up from the inside.
- Sealants. Two layers of sealant (primary and secondary) ensure complete tightness of the structure, preventing air and moisture from entering.
- Cameras. The space between the panes. The thermal and sound insulation properties depend on the number and width of the chambers.
The main types of double-glazed windows
According to the number of cameras, double-glazed windows are divided into:
- Single-chamber. They consist of two glasses and one camera between them. The thickness is usually 24 mm. This is the most affordable option, but its thermal insulation properties are minimal. It is suitable for unheated rooms (balconies, verandas) or for southern regions with a mild climate.
- Two-chamber. The most popular and balanced option for most regions of Russia. They consist of three glasses and two cameras. The thickness varies from 32 to 44 mm. They provide excellent heat and sound insulation. If you decide to buy a double-glazed unit https://www.orbita.by/okna/steklopakety/dvukhkamernye-steklopakety /,
