Pioneer company in Asturias in obtaining the Fire Resistance Certification E600 120, according to the UNE-EN 1507:2007 standard for single-sector metal smoke extraction ducts.

Applicable regulations

The ‘Código Técnico de la Edificación’ (Building Technical Code), in force since March 2006, in the section referring to garage ventilation, specifies that all ducts installed after 29 March 2007 must comply with the UNE-EN 13501- 4:2007 fire stability standard E600 120. To this end, and for sake to our commitment to excellence, Ainco was certified in May 2008 by AFITI-LICOF (Laboratorio Oficial de Ensayos del Ministerio de Industria, Turismo y Comercio), even exceeding the guidelines for galvanised sheet metal ducts in thicknesses of 0.6 to 1.2 mm, by confirming a duration of 120 minutes instead of the 90 required by the standard.
