Excellent technical characteristics, practicality and presentable appearance allowed PVC window structures to become the most popular both in the domestic and foreign markets. Manufacturers are constantly improving their products, improving its sound and heat insulation abilities.
One of the latest innovations is the five-chamber profile. Such systems have the highest characteristics and surpass their two- and three-chamber analogs. What are their features? Do such constructions have disadvantages? We will talk about this in our article.
Features of PVC windows with 5 cameras
Speaking of a five-chamber profile, you need to clearly understand what a camera is. In this case, we are talking about empty sections located in the window structure. The air inside each chamber prevents the penetration of cold into the room, which means that heat is stored much more efficiently.
The main difference between five-chamber systems is that the metal reinforcing strip is removed from the window hinges, which prevents the occurrence of cold air flows in the most vulnerable places of the structure.
If you look at the five-chamber profile in the context, we will see that it consists of 5 sections. The central compartment is supplemented by a metal profile, which is an amplifying element. On both sides there are two more hollow sections. They do not allow heat to go outside the premises, and the flows of cold air - to penetrate inside.
Design features
The high strength of plastic windows with 5 cameras allows the use of such systems in those places where reliable protection against hacking is required. The profile is suitable for operation in the temperature range from -60 to +60 degrees. At the same time, manufacturers guarantee an impeccable 40-year service for their products.
The five-chamber profile of the plastic window is an opportunity to make your house quiet and warm, however, before choosing such systems, pay attention to their parameters. Standard options are characterized by the following indicators:
- number of air chambers - 5 pcs .;
- thickness of internal partitions - 3 mm;
- the thickness of the glass unit is 42 mm;
- the thickness of the plastic profile is 70 mm;
- block reinforcement system - closed type.
These values are important in cases where you need to accurately calculate the load that the PVC system will exert on the opening. In most cases, this applies to dilapidated buildings.
How is the 5-chamber profile different from the 3-chamber?
When choosing between a three-chamber and a five-chamber PVC profile, it should be understood that the main purpose of the second type of windows is to maximize heat saving. Such designs are excellent for installation in regions where low temperatures prevail most of the year. In the central part of Russia, systems with three cameras are quite enough.
Also, consider the increased parameters of the unit with 5 cameras. If the system with a triple profile has a width of 60 mm, then the option we are considering is 10 mm wider. If you decide to give preference to just such a design, pay attention to the parameters of your window opening. Sometimes installing wide systems is simply not possible.
Comparison of technical characteristics
When choosing a three-chamber or five-chamber profile, pay attention to the technical characteristics of both systems. Their main difference is the difference in the heat storage coefficients. For units with three cameras, this indicator varies from 0.6 to 0.65 m 2 / kW, and for similar systems with 5 cameras, from 0.75 to 0.8 m 2 / kW.
In addition, advanced systems with an increased number of cameras have reliable protection against the penetration of extraneous sounds into the room. For blocks with a three-chamber profile, this figure is 30% lower.
PVC systems differ in strength. Five-chamber varieties are much more reliable, they can withstand significant physical effects. However, it must be borne in mind that, together with high strength, such structures gained additional weight. It is not recommended to install them in frame buildings.
Varieties of systems with 5 cameras
In PVC structures with a five-chamber profile, several types of double-glazed windows are used. Namely:
- single chamber varieties;
- two-chamber options;
- three-chamber species.
The selected glazing option directly affects the heat and sound insulation capabilities of the system. The total weight of the block also changes.
So, the single-chamber version consists of two glasses 4 mm thick, between which there is a gas or air gap. The total width of this variety is 24 mm. This is the most budget option with low functional performance.
The five-chamber profile with a two-chamber double-glazed window consists of three layers of glass of standard width (4 mm). This design is able to provide a high degree of protection against cold and noise. Such systems are universally installed in residential premises.
Options with a three-chamber double-glazed window consist of 4 layers. In this case, the glass thickness can be increased to 6 mm. Such varieties are ideal for use in harsh climates.
additional characteristics
The five-chamber window profile may have additional features. This includes a high degree of noise isolation, energy saving, protection against break-ins and ultraviolet rays.
The energy saving ability of the system is acquired through the use of special glasses. UV protection is achieved by applying a special tint film to the glass, and resistance to mechanical stress - thanks to the anti-vandal coating.
There are varieties with curved and decorated glass, but they are rarely found on sale and are more often made to order.
Which profile to choose: single-chamber or three-chamber?
Five-chamber systems in all respects surpass analogues with three sections, but their installation is not always advisable. Firstly, such designs are quite heavy, and secondly, their price tag is 18-20% higher than the cost of standard products with three cameras. So what kind of variety to acquire?
When choosing a window unit, rely on the natural conditions of your area and on the specifics of the environment. If the climate is close to harsh, and there is a noisy track outside the window, then options with 5 cameras will suit you perfectly.
For operation at medium temperatures (up to -25 degrees) three-chamber systems are quite suitable. If there is no need for improved sound insulation of the unit, standard options are preferable.
To summarize
When choosing window systems, cost always plays a big role. The price tag depends on the capabilities of the system and on the manufacturer. For example, a five-chamber Rehau profile with basic characteristics will have a price tag of 6,000 rubles for a standard double-wing window. In this case, products with a triple profile can be purchased for 3000-4500 rubles.
If you want to install the unit with the maximum degree of energy saving and UV protection, get ready to pay 20% more. Variants with anti-vandal coating and decorative processing have a maximum price tag. Designs of non-standard parameters can also cost an order of magnitude more expensive.
You can buy cheaper options from Chinese manufacturers, however, the quality and duration of use of such products remain in question.
