Facade blinds - characteristics

Facade blinds belong to the group of external window covers. They fit in with modern architectural trends, in which aesthetics and innovative design go hand in hand with multidimensional functionality. Modern construction requires solutions combining the convenience of use and energy efficiency, which reduces operating costs - intelligent construction. The external shield in the form of facade blinds effectively protects the rooms against heating in the summer, and protects the building against heat loss during the winter. This results in measurable savings related to eg limiting the use of air conditioning (summer), lowering bills for heating (winter).

Facade blinds can also affect the aesthetics of buildings; blend in very well with modern glass designs. Their appearance is characterized by minimalism, so in fact they blend in very well with buildings designed in various architectural styles.

Features of facade blinds

Facade blinds as modern external blinds are used not only in houses or modern residential buildings, but also in public utility buildings, office buildings, shop windows and company headquarters. They have many features and benefits that are worth knowing.

The functions of facade blinds are closely related to the place of their installation; they are placed on the outside of the window. Due to this, they very effectively protect the building against heating thanks to the fact that an air cushion is created between the blind and the window pane, and the shield itself is a barrier to sunlight. The most heat gets to the inside of the room as a result of the sun coming into contact with the glass; it can be as high as 80%. After installing facade blinds, this problem disappears, and the interior is pleasantly cool during the warm months. The same advantage is when it is cold outside so that it acts in the opposite way. The lowered facade shutter protects the building against excessive loss of heat, most of which is "escaped" through the windows. Thanks to this, it is possible to reduce bills related to interior heating in winter.

The facade blinds have another significant advantage - their construction is identical to that of classic internal blinds. The structure consists of horizontally arranged lamellas, i.e. movable slats, the inclination of which can be changed depending on the intensity of the sunlight and the angle of its incidence. Thus, the interiors do not have to be completely darkened, and fresh air will be provided inside. The rooms can also be well lit in winter, when the sun is not so intense and the blind slats can be raised all the time. The same applies to more cloudy days. The light intensity can also be adjusted using the weather automation that measures the sun's position and controls the lamellas.

Anti-theft facade blinds - as an external shield, this type of blinds can also perform anti-theft functions. The lowered armor protects the interior against break-in attempts, making it difficult to get inside. The facade blinds also soundproof the rooms and protect against the noise coming from the outside.

Flush-mounted external blinds

Installation of facade blinds

The façade blinds are made of very high quality materials, thanks to which they are resistant to the effects of weather conditions. Strips (lamellas) are made of profiled aluminum in the shape of the letter C or Z (optional). In combination with properly selected guides and shields in the form of sheet metal or aluminum cassette with an oval or square cross-section, the facade shutter significantly affects the aesthetics of the building facade. The strips themselves are available in various widths and colors and there is no problem with matching them to the color of the facade. They are made of very durable materials, additionally thermally fixed, which results in resistance to changing weather conditions (snow, strong wind, frost) and UV rays (no fading effect) color).

Facade blinds can be installed not only in buildings that are under construction, but also in ready-made buildings. In finished buildings, surface-mounted facade blinds are installed, while in buildings that are under construction, recessed facade blinds are used. Flush-mounted blinds are equipped with a cassette for flush-mounting with a projection enabling the execution of external plastering; made of extruded aluminum.

In both types, recessed and surface-mounted blinds, polyester textile elements are thermally fixed, and the ladder is additionally reinforced with Kevlar. Holes in the lamellas
are wrapped to prevent the tapes from rubbing. Number of standard strip colors - 15; additionally, it is possible to varnish it in any color from the RAL palette. The facade blinds are equipped with electric or manual drive.

What is the use of facade blinds?

The first association associated with facade blinds may bring to mind window covers on the outside of buildings that protect us from the sun. However, facade blinds are much more than simple window covers. External blinds, also known as facade blinds, are an increasingly common element of modern homes and offices. They are available in many different shapes, sizes and colors, thanks to which they can be adapted to the individual dimensions of the building, thus creating an elegant and modern look. The use of facade blinds is very wide - from residential buildings, through office buildings, to public utility buildings.

Facade blinds are made of various materials, but the most popular are those made of aluminum. Aluminum is a light material, resistant to weather conditions, which makes the blinds durable and easy to install. The simple aluminum structure of the facade blinds, with C or Z-shaped slats, is not only aesthetically attractive, but also highly functional. The facade blinds are equipped with guides that allow for smooth control of the angle of the slats. Thanks to this, the user can adjust the degree of light penetration into the interior.

How is the installation and use of facade blinds?

Installation of facade blinds is a process that requires accuracy and skill. This is especially important in the case of facade blinds that are mounted outside the building. Correct installation is crucial for the functioning of the blinds and their resistance to weather conditions.

Although the installation of facade blinds may seem complicated, in practice it is a simple and quick process. Thanks to the simple aluminum structure and ease of assembly, facade blinds are a perfect solution for anyone who appreciates comfort and speed of execution. In addition, the use of facade blinds is intuitive and simple, regardless of whether manual or electric control has been selected.

Facade blinds and external roller blinds - what are the differences?

Although at first glance, facade blinds may resemble external roller blinds, in fact they are two different products. Both blinds and roller blinds are designed to protect the interior of a building from the sun, but the way they do it is different.

External roller shutters, similarly to facade blinds, are mounted outside the building. However, their main difference is the way they regulate the amount of light entering the interior. In the case of roller blinds, it is only possible to cover the window completely or uncover it. Facade blinds, in turn, give the possibility of smooth regulation of the amount of light, thanks to the adjustment of the angle of the slats.

Can you count on energy savings thanks to facade blinds?

Energy saving is one of the most important aspects of using facade blinds. Thanks to the possibility of adjusting the angle of the slats, facade blinds allow you to control the amount of light and heat that enters the room. This not only increases the comfort of use, but also allows you to reduce the costs of heating and air conditioning.

During the heating season, open blinds allow for maximum use of solar heat, thus reducing the need for heating. In the summer, however, when the sun is high, closed blinds protect the interior from excessive sunlight, limiting the operation of air conditioning and contributing to significant savings on electricity.

Why is it worth choosing facade blinds?

Facade blinds are a perfect combination of functionality and aesthetics. Their use brings a number of benefits, from energy savings, through comfort of use, to the modern appearance of the building. Available in various shapes and colors, they can be adapted to any building, regardless of its size or style.

If you are looking for a solution that will allow you to smoothly control the amount of light entering the interior, and at the same time provide you with comfort and energy savings, facade blinds are for you. Regardless of whether you are building a new home or planning a renovation, it is worth considering the use of facade blinds.

Automation of facade blinds - How does the weather automation system work?

Smooth control is one of the key features of facade blinds. The most advanced systems allow for electric control, which guarantees precision and comfort of use. Thanks to this, it is possible to adjust the settings of the blinds to individual preferences and weather conditions.

A very interesting solution that is gaining more and more popularity is the weather automation system. It works on the basis of weather sensors that react to changes in weather conditions. Depending on the intensity of sunlight, temperature or wind strength, the system independently regulates the angle of inclination of the slats, ensuring optimal conditions inside the room.

How does the facade blinds cooperate with the air conditioning system?

Another modern solution is the possibility of cooperation of facade blinds with the air conditioning system. Thanks to this, depending on the settings of the blinds, the air conditioning system adjusts its operation, ensuring the optimal temperature inside the building.

This intelligent combination allows you to reduce the noise level generated by the air conditioning, as well as to reduce its energy consumption. This is especially important in modern homes, where care for the environment and energy saving are among the key priorities.

External blinds - How resistant are they to weather conditions?

One of the main advantages of facade blinds is their durability and resistance to various weather conditions. Thanks to the use of high-quality materials, such as aluminum, the blinds are resistant to the sun, rain or wind.

The guides on which the slats are mounted are also made of corrosion-resistant materials. Thanks to this, even after many years of use, facade blinds retain their original appearance and functionality.

How to cover glass facades? - Facade blinds!

Glass facades are a solution that is increasingly chosen in modern construction. They give the effect of spaciousness and light, but require adequate protection from the sun. This is where facade blinds come in handy.

Thanks to the ability to control the angle of inclination of the slats, the facade blinds allow you to control the amount of light entering the interior. This not only increases the comfort of use, but also protects against excessive heating of the rooms. In combination with glass facades, facade blinds create a harmonious and aesthetic duo that is not only practical, but also effective.
