European requirements for wooden door technology

The European market has very strict requirements for the process and quality of Wooden Doors, and the following are specific requirements for the process of wooden doors:

First, environmental standards
Formaldehyde release
The European market has strict limits on the amount of formaldehyde released by wooden doors. At present, Europe only accepts sheets whose formaldehyde emission limit reaches the E1 level standard, and E2 level products are not allowed to be listed in some countries. In addition, European wood-based panel manufacturers also control the E0 standard, which requires formaldehyde emission close to half of the E1 level.
EUTR regulations
The EU Timber Regulation (EUTR) requires all wood and wood products entering the EU market to be legally harvested, and companies are required to conduct due diligence to ensure that the wood is legally sourced. This includes providing detailed information on the country in which the wood is harvested, the species, the suppliers, etc.
FSC certification
The Forest Stewardship Council (FSC) standard is one of the important certifications for the European market. FSC certified wood and wood products come from sustainably managed forests and meet environmental requirements.

Second, process standards
CE certification
Wooden doors sold in the EU market must be CE certified in accordance with EN 14351-1:2006+A2:2016. The standard covers several items such as wind pressure testing, water tightness testing and air tightness testing.
Thickness of door
The standard thickness of European wooden doors is usually 40 mm or 45 mm, and the thickness of high-end wooden doors may reach 50 mm or more.
Decoration technology
European wooden doors pay attention to decoration, common decorative processes include:
Decorative line: The use of short curved lines, pay attention to the smooth transition between curves.
Door core panel decoration: composed of multiple geometric patterns, presenting a variety of styles through changes in shape and size.
Door frame decoration: the upper decorative plate and the left and right decorative plate have various shapes, emphasizing the unity of style.

Third, quality and performance
Material requirement
The wooden door materials must meet the requirements of environmental protection and sustainable development, and avoid the use of illegally harvested wood. The door core and main material are usually made of artificial composite materials that have been desensitized to reduce wet swelling and dry shrinkage.
Production technology
The production process should be scientific and reasonable to ensure product stability and reliability. For example, when assembling the board, pay attention to the height difference, the length difference and the color difference. In addition, it is necessary to carry out strict health treatment to ensure the stability of the wood.
Performance requirement
The wooden door must meet the performance requirements of wind pressure resistance, air tightness, and water tightness. For example, the insulation factor K value of doors and Windows should not be greater than 1.4W/(m²·K).

Fourth, design and style
Stylistic diversity
European wooden doors have a variety of styles, including European classical, simple European, Northern European and French. French wooden doors emphasize axis symmetry, grand momentum and fine carving.
Humanized design
The design of the wooden door should conform to the ergonomic principle, meet the function of use, while taking into account the beauty and environmental protection.

The European market has strict requirements for the process and quality of wooden doors, covering many aspects such as environmental protection standards, process standards, quality and performance, and design and style. Companies need to ensure that their products comply with relevant regulations and standards, while focusing on design and process innovation to meet the needs of the European market.
