Our products

Still do not know our products?

At Cobián Carpentry we have a wide range of wooden windows, marketed under the COSISVEN seal. All our wooden windows are made with laminated woods such as Pine, Chestnut, Oak, Iroko, Cedar. We also have mixed-material windows, which combine wood and aluminium.

Our goal is to satisfy the needs of our customers, that is why we offer multiple finishes, as well as any type of opening necessary, including large span lift-slides.

Our commitment with our COSISVEN windows is materialized in using only wood from forests whose management is environmentally sustainable. In addition, our windows have the Passivhaus certificate, and one of this certificate’s fundamental principles is the respect for the environment through energy efficiency and the reduction of the carbon footprint.
