However, beyond compliance, EN 13773 should be understood as a specification framework<\/strong>. It directly influences material selection, system design and long-term performance.<\/p>\n In practice, selecting the right fabric is not simply about passing a fire test. It is about ensuring that the textile solution remains compliant throughout the lifecycle of the space.<\/p>\n EN 13773 is specifically designed to assess the fire behaviour of curtains and drapes, which often represent large vertical surfaces within interior environments.<\/p>\n The standard evaluates:<\/p>\n For specifiers, this translates into a key requirement: The textile must not significantly contribute to the spread of fire in occupied environments.<\/p>\n As curtains are typically installed in large quantities, their performance can directly influence how fire develops within a space. For this reason, EN 13773 is essential in contract applications.<\/p>\n C1 is the highest classification level within EN 13773 and represents the benchmark for most contract applications.<\/p>\n It is typically required in:<\/p>\n Fabrics classified as C1 offer a high level of fire performance and are suitable for environments with strict safety requirements.<\/p>\n For architects and specifiers, C1 should be considered the default specification level<\/strong> in most projects.<\/p>\n C2 fabrics provide a moderate level of fire resistance and are generally suitable for spaces with lower risk or less stringent regulatory requirements.<\/p>\n Typical applications include:<\/p>\n While acceptable in certain contexts, C2 may not be sufficient for highly regulated environments.<\/p>\n C3 represents the lowest classification level and is rarely suitable for professional contract interiors.<\/p>\n These fabrics are generally not recommended for use in public buildings due to their limited fire performance.<\/p>\n For specifiers, the standard itself is only the starting point. What truly matters is how EN 13773 is applied to real textile systems within a project.<\/p>\n Architects do not specify \u201cC1 fabrics\u201d in isolation. They specify solutions such as blackout curtains, sheer fabrics or acoustic textiles, all of which must meet both functional and regulatory requirements.<\/p>\n In hospitality environments, curtain systems must deliver multiple functions simultaneously:<\/p>\n Blackout fabrics<\/a> provide complete light exclusion, while dimout fabrics<\/a> allow a softer level of light diffusion. Both must comply with EN 13773 when used in public buildings.<\/p>\n At Dabedan, these requirements are addressed through technical textile solutions specifically developed for contract interiors.<\/p>\n When specifying curtain systems in contract projects, it is essential to define:<\/p>\n Sheer fabrics<\/a> are widely used to diffuse natural light and create a sense of openness within interior spaces. However, they are often overlooked in fire safety specifications.<\/p>\n Despite their lightweight appearance, sheer fabrics must also comply with EN 13773 when used in contract environments.<\/p>\n They provide:<\/p>\n Velvet is commonly specified in environments where both performance and aesthetics are critical.<\/p>\n Typical applications include:<\/p>\n Manufacturers such as Dabedan develop inherently flame retardant velvets<\/a> designed specifically for contract use and regulatory compliance.<\/p>\n Key advantages include:<\/p>\nWhat EN 13773 evaluates in curtain fabrics<\/b><\/h2>\n
