Standards and safety requirements
Our folding sliding hardware meets the highest standards regarding airtightness, watertightness against driving rain, and wind load resistance.
Carriage for horizontal sliding and fittings for folding sliding windows
The standard DIN EN 13126-15 deals with building hardware for horizontal sliding and Fold&Slide windows as well as window doors. It defines the requirements and test methods for the durability, strength and protective function of this hardware. The characteristics of the hardware are expressed by a nine-digit classification code, as is customary in other parts of the EN 13126 series.
Windows and doors – durability test – test method
The EN 1191 standard refers to test procedures for windows and doors. It describes the requirements for the long-term operational reliability of windows and doors through cyclic load tests. These tests simulate opening and closing over a defined number of cycles to ensure that the products reliably perform their function in everyday use.
Windows and doors – product standard
The standard DIN EN 14351-1 deals with the product standard and performance characteristics of windows and external doors that are not subject to special requirements for fire or smoke tightness. It specifies how these products are to be tested with regard to their energy efficiency, watertightness, air permeability, and other performance characteristics. This standard is essential for the CE marking of such construction products in Europe.
air permeability
The EN 12207 standard refers to the classification of air permeability of windows and doors. It defines how much air can pass through a closed window or door under certain conditions. The test is carried out by applying pressure differences across the product to measure its air tightness. These measurements are important for assessing the energy efficiency and comfort in buildings.
driving rain tightness
DIN EN 12208 is a European standard that deals with the classification of watertightness for windows and doors. It specifies how much water can penetrate a closed window or door under certain conditions. The test involves applying water pressure to the external surface of the product to assess its ability to prevent water ingress. This assessment is important for protection against moisture damage and to ensure energy efficiency in buildings.
resistance to wind load
The DIN EN 12210 standard relates to the resistance of windows and doors to wind loads. It specifies how these building components must be tested under various pressure conditions to assess their ability to withstand wind loads. These tests are crucial for ensuring the safety and stability of buildings during strong winds or storms.General questions about folding sliding hardware
