Screen blinds are one of the most widely used elements of modern shading. They can significantly reduce interior overheating, help protect privacy and improve the energy balance of the house. However, in order for them to function in the long term and at the same time look nice, it is important to properly prepare the construction detail around the window and carefully install it. In this article, you will learn step by step how screen blinds work, where they fit, how to prepare the building so that the installation goes without complications, and what not to underestimate when installing them.

What are screen blinds and where are they most often installed?

Screen blinds are external textile curtains made of strong technical fabric. Their main function is to stop solar radiation before the glass, which leads to a significant reduction in the heat load of the interior. At the same time, they allow natural daylight and a partial view outside, thanks to which they create a pleasant and comfortable environment without the need to use air conditioning. They are most often installed on windows and sliding doors of family houses, in office buildings to improve thermal comfort or on pergolas and terraces as protection from the sun and light wind. In addition, modern screens can be connected to smart home control, timers or wind and sun sensors, which further increases their user comfort and durability.

What are their advantages?

• Significant reduction in interior overheating - they stop solar radiation before the window and maintain a pleasant temperature at home even on hot days.
• Energy saving - they help reduce the need for air conditioning and improve the energy balance of the building.
• Privacy protection - they allow you to see outside, but the interior can be seen from the outside at a minimum.
• Constant access of daylight - the interior remains illuminated, without unpleasant glare.
• Modern facade aesthetics - screens look clean and elegant, especially if they are hidden in a purenit or PURbox element.
• Wind and weather resistance - the technical fabric is strong, stable and maintenance-free in the long term.
• Suitable for windows, large glazed areas and pergolas - screen roller blinds adapt to any type of building.
• Smart control option - integration with motors, wind/sun sensors and smart home systems for maximum comfort.
• Quiet and smooth operation - high-quality screens move quietly and without vibrations, which increases their lifespan.

Can screen blinds be installed by yourself, or is professional installation required?

The answer depends on the specific type of screen blind and where it is to be placed. Simpler, recognized systems can sometimes be installed by yourself, if the user has basic craftsmanship and follows the manufacturer's instructions. For larger dimensions, installation into a facade or when using electric motors, it is better to choose professional installation.

Incorrect installation can damage your facade, cause instability of the blind, shorten the life of the system or affect the manufacturer's warranty. Especially with electric control, it is necessary that the installation and connection to the electrical installation be carried out by a qualified electrician. If screen blinds are installed in a new building or in insulation, we recommend having a construction detail ready before the facade is completed.

How to prepare a new building for screen roller blinds so that the installation is as simple as possible?

Preparation for screen roller blinds should be addressed at the project stage, because a properly designed lintel and lining detail affects the ease of installation and the resulting energy efficiency of the house. In modern low-energy buildings, it is standard to plan for exterior shading in advance to avoid problems such as lack of space for the box or an unsuitable anchoring location. System elements play a major role in this, which allow for the elegant integration of screen roller blinds into the facade without thermal bridges and without compromises in design.

Purenit boxes and lintel PURboxes create a precise, high-quality insulating and structurally solid space for the future screen roller blind. Thanks to this, the screens can be installed after the completion of the shell construction or even after the final facade, without the need to interfere with the facade. These boxes have excellent thermal insulation properties, enable solid anchoring of the guide rails and the roller blind box, and at the same time significantly simplify the work of installation companies. They can be supplemented with system lining or mounting pads, which ensure precise positioning of the guide rails and eliminate the risk of anchoring into soft insulation.

What is the general assembly procedure?

Although the exact assembly procedure may vary depending on the specific roller shutter manufacturer, there are a few general steps that assembly usually involves. First, accurately measure the width and height of the opening or structure on which the screen roller shutter will be installed. The substrate must be flat, stable and strong enough to support the box and guide rails. Insulation itself does not provide strength, so have supporting elements ready, such as purenit blocks or system lining.

Then position the brackets according to the roller shutter manufacturer's assembly instructions. Remember to maintain precise spacing and the correct type of anchoring in relation to the substrate material to prevent system instability. After the brackets are attached, the screen roller shutter box is installed. For larger widths, the box can be quite heavy, so it is better to carry out the assembly with two or three people. The box is then secured according to the technical instructions. The next step is to install the guide rails, which are attached either to the facade, window frame, pergola structure, or to the system lining, if it is prepared in advance.

After mechanically fastening all parts, it is time to test the operation. Pull the roller shutter several times and lower it to its full range to check that the fabric rolls up straight, nothing rubs and the lower stops work properly. For motorized screens, the end positions and controls are set at the same time, or the roller shutter is integrated into the central house control according to the electrical installation project.

What tools and materials do you need for installation?

To install a screen roller shutter, basic installation equipment is usually used, which includes a tape measure, pencil, spirit level or laser, a drill, appropriate drills, dowels and screws suitable for the specific material. In some cases, it is necessary to use a ladder or scaffolding, especially if the roller shutter is installed on a higher floor. Depending on the type of fasteners, Allen keys, bits or screwdrivers may be needed. It goes without saying that protective equipment such as work gloves and glasses are used. If the roller shutter is installed in a purenit or PURbox element, the recommended anchoring elements listed in the technical documentation of these products are used.

What are the most common mistakes made during installation?

The most common mistakes include anchoring to the insulation itself, because the insulation does not provide sufficient load-bearing capacity and the roller shutter may loosen over time or damage the facade. Another typical problem is insufficient space for the box, if the roller shutters were not included in the project and the box cannot be hidden in the facade. We also often encounter inaccurate measurements, when the roller shutter does not fit into the lining or prevents the window from opening. Errors also occur when the manufacturer's installation instructions are not followed, especially when the brackets are incorrectly positioned or the number of anchors is insufficient. Incorrectly designed thermal insulation details can cause thermal bridges, condensation or cooling around the window. This is where ISOparts system elements have a great advantage, because they help eliminate these problems in a timely and permanent manner.

How can we at ISOparts simplify the installation of screen blinds for you?

At ISOparts, a Czech family business, we specialize primarily in purenit boxes, flush-mounted PUR boxes, linings and mounting elements designed specifically for the installation of exterior shading. If you are planning to install screen blinds in a new building or during renovation, the system solution will significantly simplify the preparation of the building and the installation itself.

The lintel PURbox creates space for the screen blind box directly in the lintel and allows for precise insulation. The purenit boxes then serve as a prepared structural element into which the screen blind can be placed without the need to deal with additional facade modifications. The system linings and mounting pads facilitate firm and precise placement of guide rails and reliable anchoring even in places where the insulation would not be sufficient.
