External doors are regulated in standard EN 14351-1. This standard provides for mandatory CE marking for all doors that are built into exterior walls.
External doors with CE mark
System Schröders external doors have a CE mark in accordance with the building inspection regulations.
Within the EU, external doors must have a CE mark. The CE mark must state the different performance characteristics of the door. For each external door, specification of the heat transfer coefficient ("U-value") is compulsory.
External doors can be equipped as an option with additional performance characteristics, such as intrusion protection or sound insulation. If the external door satisfies further performance characteristics, the class that is achieved is also indicated on the CE mark. If there is no requirement for a performance characteristic, "npd" ("no performance determined") is entered on the CE mark for this performance characteristic.
Proven performance characteristics
All performance characteristics must be demonstrated by means of tests.
With the new System Schröders ASN range of external doors, System Schröders meets all performance requirements which are placed on external doors.
The following classes and values have been achieved for System Schröders ASN doors in the performance characteristics which are important for exterior doors (testing by ift, Rosenheim and PIV, Velbert):
Performance classes for external doors
Heat transfer coefficient UD ≥ 1.8 W/m2K
(EN ISO 1077-1),
Resistance to wind load up to class C5
Water tightness up to class 8A
Acoustic performance up to RW (C;Ctr) = 53 (-1;-5) dB
(EN ISO 717-1),
Airtightness up to class 4
Burglar resistance up to class RC4
(EN 1627 ff).
Exterior doors in a single and double-leaf design
"System Schröders ASN" external doors are available as both single and double-leaf versions. On request, the doors can be fitted with glazing. A top panel or skylight are also possible. Of course the doors can be produced in stainless steel as an option.
With the new "ASN" external door range, System Schröders has the right door for a wide variety of requirements with the corresponding required certificates and the necessary CE marking.
