Aluminum profile for windows - which one is better? The list of building materials from which window systems can be made is not limited to plastic alone. PVC windows are incredibly popular, but at the moment there are metal and wood structures on sale that surpass them in many ways.
New technologies have made it possible to eliminate material shortcomings, and for this reason, the aluminum profile for windows has become more often used for glazing apartments and private houses.
Advantages
Modern windows made of aluminum profiles are different from those that were used for construction several decades ago.
The list of advantages is impressive:
This makes it possible to make frames thinner than standard plastic frames, which in turn gives more illumination. Also, the frame made of aluminum is less susceptible to damage, and the margin of safety is designed for double-glazed windows with a huge weight. The risk of sash deformation or sagging is minimized.
Please note, that silicon and magnesium are added to aluminum during production, which makes the profile more rigid and resistant to corrosion.
Manufacturers give a guarantee from 50 to 80 years, but if the seal and fittings are timely replaced, the windows will last even longer. Also, aluminum is not afraid of exposure to the sun and moisture, and can easily withstand large temperature drops (from -85 to +210 degrees).
An aluminum frame, even without special fittings, can withstand at least 10 minutes of a burglar with a hand tool.
Interesting facts!
It is thanks to such a number of advantages that the production of windows from aluminum profiles has become so popular.
Disadvantages
Like every material, this metal also has its drawbacks, but there are an order of magnitude less of them than advantages:
There are two categories of aluminum window profiles - cold and warm.
With the same thickness, the difference between them is in the internal structure, and in order to see it, it is not at all necessary to saw the element in half - on the Internet, manufacturers post section drawings of the models, which can be found in DWG format. The following photo will help you understand what is the difference between the varieties.
So, the cold profile has no elements for insulation, and inside it there is only one chamber without layers, so it will freeze through in winter. Cold-type aluminum structures are suitable for balconies, loggias without heating, verandas or utility rooms. The advantages of this option are the lightness of the fittings and low weight.
The warm profile contains a longitudinal insert with polyamide fiberglass. Such materials have a low coefficient of thermal conductivity - 150 less than that of pure aluminum. The insert can be from 18 to 35 mm thick, and in this case the thermal break will not let the cold pass.
This design makes it possible to approach soft metal windows in terms of heat retention in PVC or wooden frames, so they can be installed in the living area. It is interesting that the coefficient of resistance to heat transfer will be equal from 0.
55 to 0.57 m 2 * C / W.With a thermal break, which is obtained from a multi-chamber profile with a glass unit with a width of 3 to 4 cm, the coefficient of resistance to heat transfer increases to 0.63 m 2 * C / W.
In windows and doors made of aluminum profiles, the thermal break chamber is hollow, and for this reason, even at a temperature of -10 degrees, they become covered with condensation.
Such structures are the coldest, and the coefficient will not be more than 0.44 m 2 * C / W.
Hardware for aluminum window frames differs from the elements that are in PVC construction. ,
They can be divided into two types:
They do not require additional holes and a template, so they can be considered the most technologically advanced.
If everything is extremely simple with fittings, then with a seal it is a little more complicated.
The seal is required in order to protect against drafts, as well as to protect the profile from mechanical damage, and to extend the life of the entire structure.
It is used on all doors and windows with any type of opening and can be divided into 3 types:
If you decide to replace the seal, it is better to buy materials from the same company that the manufacturer used. In the store, make sure the seal stretches a little and does not crack.
For aluminum window systems, the quality criteria are set by GOST 21519-2003.
For this reason, on the basis of GOST, in the rating of the best manufacturers, which were selected based on user reviews, highlighted :
After it is carried out, a protective film is formed on the surface. The main area of application is cold glazing. Such profiles are often used in window blocks by most manufacturers, and even such eminent ones as Kaleva-Light.This is a special glazing system for balconies and loggias, which allows you to make the most of the available space and ensure the maximum flow of light through the glass. Kaleva is indispensable for "broken" loggias, and at the same time, various schemes for opening windows are possible.
The company's products are adapted for Russian conditions, and the prices are much lower than foreign models, while the quality is very good.
To calculate the cost of glazing windows with an aluminum profile, you should first consider the parameters on which the final cost will depend.
These should include the following:
The final cost will largely depend on the quality of the components used. The construction price will be increased if multi-circuit seals are used. The best fittings manufacturers are the German company Roto and the Italian company Giesse.
So, it turns out that the cost of one window structure made of cold-type aluminum with a single-glazed unit starts from 3,800 rubles / m 2 . A warm window with a double-glazed window will cost from 4,500 rubles / m 2 . And yet it is better to use the warm aluminum profile of the famous brand for windows, which guarantees the quality of the manufactured products.
