About us

Created in 1990, Fadasa (Fábrica Accesorios Doble Acristalaciones, S.A.), was born with the purpose of meeting the growing demand of the double insulating glass sector with the supply of high precision, quality and technology parts.
The constant evolution of the company forces the transfer of its premises to its current location, in modern facilities of 4,500 m2, in the Silvota de LLanera industrial estate (Principality of Asturias).
