Outdoor blinds

Outdoor blinds fulfil many functions and optimise the room climate, depending on the season. In summer, blinds installed outside reduce the need for cooling by preventing direct sunlight and heating up of the rooms. Air conditioning costs can thus be reduced. At night, the lowered blinds let cool air into the interior of the building and at the same time protect against insects. Hence the blinds also serve as insect screens with perfect air permeability.

While blinds installed outside reflect and absorb the sun light even before it hits the glass, sun protection installed inside allows the sunlight to enter through the glass and increase the room temperature. The intensity of this effect, also known as heat trap or greenhouse effect, can vary, depending on the type of glazing. Outdoor blinds protect more effectively from heat and thus provide a pleasant and constant room climate.

The energy efficiency of buildings plays a central role in the context of sustainability and climate neutrality, since most of the energy required in Germany is used to provide heat. The use of air conditioning and heat pumps for cooling in summer is also becoming increasingly popular. Sun protection systems installed outside can save a lot of energy and significantly enhance the energy efficiency of a building.

In winter, the sun light is used to increase the energy input into the building and thus minimise heating costs. The air in the gap between the window and the lowered blinds serves as an additional insulation and keeps the heat inside the building.

In summer, rooms without blinds can quickly overheat. A textile sun protection installed outside reflects and absorbs the sun’s rays even before they strike the glass, thus preventing the interior from heating up quickly. If the room has an air-conditioning system, further potential savings are possible, as the need for cooling is significantly reduced.

Standard heroal textile screens are equipped with a motor, offering you additional options to reduce energy consumption as much as possible by adding a timer or a weather station with sensors.

The renowned German testing institute Institut für Fenstertechnik (ift) Rosenheim, in cooperation with the Industrial Association for Technical Textiles, Roller Shutters and Sun Protection e.V. (ITRS), has revised the Energy Label for windows in order to create more transparency for planners and consumers, and to prove the effect of roller shutters and sun protection on the energy balance. With the Energy Label, a uniform standard was created for the insulating effect of different textiles and curtains in combination with the window. Even with high-quality windows, blinds and curtains still have a considerable effect on energy savings – in summer and in winter. As with electric appliances, the efficiency is rated in terms of a set of energy efficiency classes from A to G. The Energy Label is issued by the fabricator, who determines the required energy parameters and declares them for his products. In order to determine the contribution of an outdoor blind or curtain to the ultimate energy savings, various factors must be taken into account. These include, among others, the orientation of the window, the average sunshine duration, cloudiness and shading duration, as well as the kind of window installed. The Energy Label for windows draws attention to the fact that there is more to roller shutters and blinds than design, protection from weather or burglary resistance.

You can easily retrofit your windows with blinds installed outside in the course of renovation or modernisation. heroal textile screens are perfectly suited for a retrofit due to their low winding diameter and the resulting small box size; and they fit perfectly and almost invisibly into the look of the building. You can choose between the installation using a visible surface-mounted box or an invisible plaster-base box integrated into the façade. Surface-mounted boxes in different sizes, designs and colours allow you to individually adapt the sun protection to your building, and provide for an easy fixture to the outer shell of the building. Other than the installation of the sun protection, there are no other changes to the building required, such as plastering or painting.

The blinds unobtrusively blend into the look of the building thanks to the combination of panel boxes with a subtle design and the slim rails to guide the sides of the zip screen heroal VS Z and the textile sun protection heroal VS. With the heroal VS C, the sides of the blinds are guided via high-quality stainless steel ropes, accentuating the slim design even more. As opposed to the heroal VS Z, the variants heroal VS and heroal VS C, however, are not equipped with zip technology at the sides, so that they should only be used in regions where high wind speeds are not expected.

Thanks to the different variants of heroal sun protection products, the wide range of design options and the comprehensive choice of colours, you will certainly find the blinds that fulfil the functional requirements you have and match the style of your house.

Standard sun protection by heroal is equipped with an electric control, which provides for the automatic opening and closing of the blinds by means of sensors, remote controls or apps. Electric controls increase the ease of use, save energy and ensure a long service life of your blinds. In combination with a sun sensor, the blinds open or close depending on the angle of the sun. This ensures a pleasant room climate all day long, without the need for air conditioning. In combination with a wind sensor, your blinds automatically retract once a certain wind speed is reached. This ensures that you can enjoy your textile outdoor blinds for a long time.
