Installation of Interior and Exterior Doors in Belgium: Standards, Requirements and Costs
Installing interior and exterior doors is a key element in ensuring the security, comfort, and energy efficiency of your home or building in Belgium. Whether you're in the Flemish region, Brussels-Capital Region, or Wallonia, it's essential to understand the current standards and technical criteria that govern this work. Discover everything you need to know before installing doors in your home in this article.
Belgian Standards for Interior and Exterior Doors
In Belgium, several standards govern the installation of doors to meet fire safety, energy performance, and mechanical strength requirements. Here's an overview of the main applicable standards:
1. Standards for Interior Doors
- NBN B 25-002-6:2023 : This standard defines the performance required for interior doors intended for pedestrians, in alignment with European standards.
- Standard Dimensions : Although the NF P 01 005 standard is French, it is often used as a reference for interior door dimensions in Belgium. Standard heights are generally 204 cm , with common widths of 63 cm, 73 cm, 83 cm or 93 cm .
2. Standards for Exterior Doors
- NBN B 25-002-2:2022 : This standard specifies general performance for exterior pedestrian doors, including wind exposure classes and durability criteria.
- Energy Performance : For exterior doors, the thermal transmission coefficient ( Ud ) must be less than or equal to 2.0 W/m²K to ensure effective thermal insulation.
3. Fire Safety
- NBN B 25-002-7:2023 : This standard governs the performance of pedestrian fire doors, replacing the old STS 53.1:2006 standards. Since July 1, 2022 , projects requiring a building permit must use class EI 1 fire doors, offering enhanced protection against fire.
4. Burglary Resistance
EN 1627 to 1630 standards apply to armoured doors and other burglar-resistant joinery. These standards classify doors into six resistance categories, ranging from RC1 (low resistance) to RC6 (high security).
Technical Requirements for Installation
To ensure a durable and compliant installation, here are some important points to consider:
- Interior doors should be installed in sufficiently dry buildings, with relative humidity between 30% and 60% .
- Climatic conditions must be stable during installation to avoid premature deformation or deterioration.
- Door dimensions must comply with accessibility standards to allow practical use, particularly for people with reduced mobility.
- Particular attention should be paid to the ease of opening and closing of doors, as well as their sound insulation.
Average Cost of Door Installation in Belgium
The cost of door installation varies depending on the type of door, the materials chosen, and the complexity of the work. Here's a guideline to help you estimate your budget:
Important note : These prices generally include the cost of the door and its installation. Additional fees may apply for specific work (frame adaptation, installation of special locks, etc.).
Why respect standards?
Complying with Belgian standards for the installation of doors is not only a legal obligation, but also a guarantee of quality and safety:
- Fire safety : Class EI 1 fire doors effectively protect against the spread of flames.
- Energy efficiency : Good thermal insulation reduces your heating bills and improves living comfort.
- Burglary protection : Doors certified to EN 1627 to 1630 offer added peace of mind
Conclusion
Installing interior and exterior doors in Belgium is a significant investment that requires in-depth knowledge of current standards. By complying with technical requirements and selecting suitable materials, you guarantee the security, durability, and energy efficiency of your home.
If you're considering door installation or replacement, be sure to consult a qualified professional to ensure full compliance with Belgian standards. For more information on financial assistance available for renovation work, visit the official websites of the Flemish, Brussels, and Walloon regions.
