Additional profiles Rehau (Rehau)

Often, due to the installation features when finishing surfaces adjacent to the window, the base width of the main frame profile is not enough. Often, this situation is encountered when glazing balconies and loggias. Some craftsmen resort to the “trick” of covering the gaps with plasterboard or other finishing materials, which is a little less than a complete mistake. Especially if it interferes with the opening of the sash in any plane.

Fortunately, engineers from well-known brands managed to solve this problem today; additional profiles for plastic windows can be found from almost any manufacturer. But what is it? How to use it? What types of extras are presented in company catalogs? Can I install them myself? The Smart Windows team decided to answer these questions and share important, useful, interesting and relevant information with all readers of our blog!

Why using universal additional PVC profiles is convenient and profitable

Universal additional PVC profiles

- an excellent solution for manufacturers of plastic windows. Perhaps some companies have not yet appreciated the benefits of working with them and do not understand how convenient and profitable it is.

Ease of use of additional profiles

It is more convenient to use universal additional profiles, since there is no need to keep in stock a large number of different additional profiles for each profile system.

Many manufacturers of plastic windows simultaneously use several PVC profile systems (KBE, VEKA, REHAU, EXPROF, etc.). And each system needs its own

additional profiles (connecting strips, statics, expanders, 90 degree corners and PVC pipe, etc.). Therefore, it is necessary to allocate space for them and ensure reliable storage. But at the most inopportune moment, as often happens, you may still not have the necessary additional profiles in your warehouse. By choosing Rehau universal additional profiles, you can be sure that such a problem will not arise with them, since they can be used with any main profiles with an installation depth of 58 and 70 mm.

Benefits of using additional profiles

Use universal additional profiles

more profitable, since you can buy large volumes of profiles at lower prices.

Often the consumption of additional PVC profiles is insignificant. Therefore, companies working with a large number of different PVC profile systems are forced to buy additional profiles almost individually. The cost of additional profiles in this case is much higher.

Application of additional profiles

The height of the frame window profile on the street side is about 6 cm. Approximately 3 cm should be the visible part of the profile, respectively, 3 cm extends beyond a quarter of the opening. Wide quarters (more than 8 cm) determine the excessive width of the thermal insulation layer and a high probability of poor quality performance. Manufacturers of polyurethane foam determine the optimal filling width of 1-6 cm at an ambient temperature of about + 20°C. For wider gaps, installation of additional profiles is provided.

In some cases, there are no quarters in window openings (for example, when glazing balconies), and subsequent finishing work involves thickening the walls or ceiling adjacent to the window. In these cases, additional profiles allow you to change the dimensions of the frame part of the window and correctly carry out the connection.

Installation of additional Rehau profiles

The profiles are fixed to the frame or to each other by simply snapping them into place. Depending on the size of the additional profile and installation conditions, clamps

or other tightening devices.

To ensure airtightness

the joint between the profile elements is sealed with silicone. To avoid thermal convection, the inside of the joint cavity is filled with polyurethane foam, PSUL or other suitable material. It is also necessary to completely seal the ends of the additional profiles.

To increase the static characteristics of the Rehau

Rehau additional profiles: design

The front surfaces of the additional profiles are extremely smooth. They are made from the same type of RAU-PVC

, which determines high resistance to solar radiation and precipitation. Additional Rehau profiles do not change color and shape for a long time. The service life is comparable to window profiles.

Extensions and strips in balcony structures

February 15, 2016

Making a loggia or balcony warm is a natural desire of any owner of a city apartment. In the end, there is no such thing as extra square meters, and if getting a significant increase in them due to the balcony area is a very real idea, then why not take advantage of it? So people install warm plastic glazing, which is really a big step towards establishing a “residential” microclimate on the territory of a balcony or loggia. But do not forget that the balcony is not only the area where the PVC window structure is installed. This is also the floor, walls, ceiling. All this requires additional insulation, for which a wide variety of materials are used. And these materials, which perform thermal insulation work along the entire perimeter of the balcony or loggia, can be adjacent directly to the warm plastic glazing, and in some cases even support the double-glazed window. All this is “not comme il faut” not only from an aesthetic point of view, but also for practical reasons, since such close proximity can harm plastic windows. To prevent such a situation, experts use so-called “extras,” which we will discuss in more detail in this article.

To understand what extensions or extension extension profiles are, let’s look at an example of their use when installing door frames. Here they are used no less often, and perhaps more often, than in the case of window structures. So, if the thickness of the wall in the area of the doorway is greater than the door frame that will be installed in it, then extensions are used that seem to increase this very thickness until it reaches acceptable dimensions. About the same thing happens with warm plastic glazing. With the help of additional (expansion) profiles, a certain “extension” of the plastic structure is carried out, but not in order to match the thickness of the wall, as was the case with doors. What is the purpose of this “increasing” of extras? Firstly, as we have already said, this excludes the direct proximity of the double-glazed window and insulating materials, the “neighbors” of which in this case are our additional profiles. Secondly, the absence of physical interference from the materials described above will help to avoid difficulties with the free opening and closing of window sashes on a balcony or loggia.

Accessories for plastic windows: application features

Additional elements for windows are used wherever it is necessary to expand the frame for installing windows with subsequent finishing of slopes and other surfaces with various decorative materials. But most often they are used:

When glazing loggias and balconies, where subsequent finishing of the ceilings is implied;
In the case when the size of the opening turns out to be larger than the dimensions of the purchased frame, as an alternative to more expensive and slower methods of extension;
If it is necessary to insulate or cover slopes with plasterboard from the inside;
Not only for extensions, but also for increasing the rigidity of the window structure or balcony glazing.

It is worth noting that, like a window profile, the extension can be covered with various decorative films.

Portal about construction

In order to maintain comfort in an apartment or house, it is necessary to constantly keep the living space warm. Today, modern technologies improve the quality of human life in many ways. Thus, a new custom-made metal-plastic window contributes to a more aesthetic appearance of the opening, and most importantly, better heat retention in the house. Of course, despite the quality of the profile, air leaks can occur due to improper installation of the structure or certain building features. To improve these indicators, a wildcard profile was created.

Additions for plastic windows: what is it?

Window additions appeared relatively recently. But they have already become a solution to a problem due to which the performance characteristics of window structures and the appearance of buildings in general “suffered.” They are a molded plastic product that is hollow inside and is attached to the window frame along its outer perimeter to increase the total area of the structure.

The additional profile is attached to the structure with a special locking connection: the groove-to-groove fixation makes it completely moisture- and airtight. It is worth noting that the molded elements can be connected to each other, which allows you to expand the frame to the desired size, and also simplifies installation even in the most difficult situations.

Purpose of the part

So, a wildcard profile is needed:

to protect the main profile during storage, lifting to the installation site and transportation;
quick and high-quality leveling of the main structure for reliable fastening;
ensuring the absence of cold bridges under the window sill;
installation of additional window parts.

It is worth noting that installing a stand profile enhances all of the listed advantages when using polyurethane foam. Together, the strip and foam provide maximum energy savings and reliability of the installed profile.

It is interesting that experienced specialists in big cities do not consider the cost of this element separately. Each custom window already has a price taking into account the cost of this profile. Less experienced companies rarely use the element in question in their work by default, so it is still possible to purchase a window sill profile as a separate element.

Please pay attention! “Window Company VESTA” does not supply additional profiles separately. Only available when ordering with glazing designs.

What is a part

This element is always made of plastic of increased strength, resistance to temperature and moisture. This difference can be seen even by the color of the material, which is always slightly darker than the plastic of the window itself.

Externally, the stand profile for PVC windows is a strip necessary for reliable fastening of ebbs and window sills. During manufacturing, the part is given a certain design and cross-section, which, during the service of the element, allows you to securely attach additional parts of the window profile to itself and retain the maximum amount of heat in the house. During installation, the window sill must be as long as the entire window. In this case, the strip should fit as tightly as possible to the insulating material.

Today, such an additional element is already considered a necessity for high-quality work and is manufactured according to certain features of window profiles. So, if the window has a standard set of external sills made of any metal, it is recommended to use a specialized profile with a “cap” for installation. Such an element can significantly facilitate the installation and fastening of additional parts of the window, as well as provide protection against water flow into the room.
