Large glass surfaces are visually appealing, but in the summer they act as huge collectors of heat energy. When the sun shines directly on an unprotected window, the interior spaces overheat in a very short time to the point that living or working becomes unbearable. The heat load accumulates in the walls and floors during the day, which means that the room remains hot even late at night.
Relying solely on internal cooling with air conditioning in such architectural designs no longer makes sense. Air conditioning merely cools the already overheated air in the room, which is extremely energy-wasting and often leads to unpleasant drafts and dry air. A true engineering approach to solving overheating requires preventing the entry of heat energy, which can only be achieved with an external physical barrier.
External blinds are the only effective barrier that intercepts the sun's rays on the outside of the facade. Among all the available solutions on the market, advanced external roller blinds prove to be the most optimal choice for modern buildings, as they combine high shading efficiency with maintaining the clean, minimalist lines of the architecture itself.
What actually sets the ZIP screen apart from classic external blinds? The key innovation lies in the fabric guiding system itself. A special zipper (ZIP) is welded to both side edges of the canvas and firmly clamped into the side aluminum guides. This mechanism ensures that the canvas is fully taut at all times, without wrinkles and without gaps through which light or even annoying insects could penetrate.
Another outstanding advantage of this technology is the choice of specific technical screens. By using high-quality screen fabrics, you can reliably protect the object from heat (they retain up to 90 % of thermal energy), while the micro perforations in the screen still allow a view outside. This prevents the feeling of being cramped and preserves natural lighting in the room without annoying glare on computer screens.
Due to the fixed attachment of the canvas to the side rails, ZIP screen awnings also boast exceptional resistance to extreme weather conditions. They can withstand very strong gusts of wind without rattling, falling out of the rails or getting damaged. It is precisely because of this mechanical stability that they are the ideal choice for high-rise buildings, exposed terraces and pergolas, where classic solutions quickly fail.
Modern buildings are not just a collection of bricks and glass, but are becoming smart ecosystems that actively respond to their surroundings. Manual control of blinds, especially in large commercial or residential complexes, is time-consuming and mostly inefficient, as people only react when the space is already uncomfortably hot. The solution is the complete digitalization of facade shading.
This transition to automation represents a true revolution in indoor climate management. External protection works proactively, the building breathes and protects itself, and users enjoy a stable and comfortable indoor temperature from early morning to late evening, regardless of weather fluctuations outside.
The highest level of automation is achieved by implementing smart weather sensors on the facade or roof of the building. Sun and temperature sensors constantly measure the intensity of solar radiation. When the values exceed a predetermined limit (for example, during strong summer midday sun), the system detects this and automatically sends a signal to the motor drives.
Real-time responsiveness means that ZIP screen shades immediately lower and protect glass surfaces before the heat load breaks through the building's insulation. This feature is especially valuable when you are away from home or the office. The building is protected from the heat wave completely independently, and you return to a pleasantly cooled space.
The system also works with wind sensors (anemometers). Although ZIP technology is extremely durable, in the event of strong hurricane-force winds that exceed safety limits, the blinds automatically and safely retract into a protective cassette. This automation is aimed at protecting both the climate in the room and the protection and longevity of the investment itself.
In addition to fully automated sensor solutions, users always have the option of personalization. Through an advanced yet user-friendly mobile application, an individual can take full control of each individual blind, regardless of where in the world they are currently located.
For example, if you’re at work and realize that an unexpectedly hot day is coming, you can lower the shades on the south and west sides of your house with a single tap on your smartphone screen. You can also create schedules and routines; for example, the shades will automatically lower to 80°C every day at 2:00 PM during the summer months, preventing the worst of the afternoon heat.
This digital control also integrates seamlessly with voice assistants such as Google Home, Apple HomeKit or Amazon Alexa. You can simply say a command from the comfort of your living room and the entire exterior facade will adapt to your wishes, representing the absolute pinnacle of modern living.
Air conditioning in modern, heavily glazed buildings represents one of the largest costs in building maintenance and operation. Since air conditioning compressors consume huge amounts of electricity to cool the air, any measure that reduces the need for their operation is an extremely profitable long-term investment.
With the smart and consistent use of external shading, the temperature inside the room has been proven to be reduced by several degrees Celsius. Due to this preventive protection, the air conditioning system is turned on less often, operates at lower power and consumes significantly less electricity. This is directly reflected in lower monthly costs, while at the same time extending the lifespan of the air conditioning units themselves.
