Installation of Blinds in Belgium: Technical Standards and Regulations
Installing blinds is a key element in improving the thermal and visual comfort of a building, whether residential or non-residential. In Belgium, technical regulations and standards govern these installations to ensure their safety, performance, and durability. Discover in this article the main applicable standards, the energy requirements for buildings, and the aspects to consider when installing stores.
Technical Standards for the Installation of Blinds
NF DTU 34.4: The National Reference
The NF DTU 34.4 document is a national reference for the installation of shutters and blinds. Although its application is voluntary, it is often used as a contractual basis between professionals and clients. This document can also be reviewed in the event of a dispute to clarify the parties' responsibilities.
- Specific application for non-residential buildings : In the case of external Venetian blinds, special attention must be paid to safety. These devices must be equipped with an automatic response mechanism when the wind speed exceeds a limit set by the manufacturer. This requirement is intended to prevent damage caused by adverse weather conditions.
NBN EN 14202: Electric Actuators
The NBN EN 14202 standard applies to electric drives used for outdoor stores and window closures. It provides precise guidelines for the use of electric motors, ensuring their reliability and compatibility with modern awning systems.
- Benefits : Operators that comply with this standard ensure smooth and secure operation of blinds, while minimizing the risk of malfunction.
Energy and Environmental Requirements
Energy Performance of Buildings (EPB)
Although EPB requirements do not directly address blinds, they strongly influence the overall design of buildings in terms of energy efficiency. Blinds can play a crucial role in thermal regulation and reducing energy loss.
- Thermal regulation : Outdoor stores, particularly awnings, help limit excessive solar gain during warmer months. This helps reduce energy consumption related to building cooling.
- Winter insulation : Certain types of blinds, such as insulated roller shutters, can also improve thermal insulation in winter.
Energy Performance Diagnosis (EPD)
Blinds can positively impact a building's energy performance rating by improving summer comfort and, in particular, air conditioning requirements. However, there are no specific standards related to blinds within the energy performance rating. Their impact is generally considered indirectly, through their contribution to thermal regulation.
Other Important Aspects to Consider
Choice of Materials
The choice of materials for blinds depends on the specific needs of the building and its location:
- Weather-resistant materials : For areas exposed to strong winds or frequent rain, choose sturdy materials such as aluminum or reinforced PVC.
- Insulating materials : If the main objective is to improve thermal insulation, opt for blinds with materials specially designed for this function.
The cost of installing blinds varies depending on the type of store, the materials chosen, and the complexity of the installation. Here's a guideline to help you estimate your budget:
Type of blinds | Average Price (excl. VAT) |
|---|---|
Exterior Venetian blinds | €200 – €500 per unit |
Awnings | €800 – €2,000 |
Motorized roller shutters | €300 – €800 per unit |
Classic interior blinds | €100 – €300 per unit |
Note : These prices are indicative and may vary depending on the region (Flanders, Brussels, Wallonia) and local providers.
Why respect standards?
Complying with current technical standards and regulations has several advantages:
- Increased safety : Standard-compliant devices minimize the risk of weather-related accidents.
- Durability : Standard-compliant materials and systems provide longer service life.
- Legal compliance : In the event of a dispute, compliance with standards can serve as proof of proper execution of the work.
Conclusion
Blind installation in Belgium is based on well-defined technical standards, such as NF DTU 34.4 and NBN EN 14202, which guarantee the quality and safety of installations. Furthermore, blinds play a growing role in the energy efficiency of buildings, contributing to thermal regulation and reducing energy losses. Whether you are in Flanders, Brussels, or Wallonia, it is essential to consider these aspects to ensure a successful and lasting installation.
If you are considering installing blinds, consult a qualified professional to help you choose the materials and systems best suited to your needs.
