The Duero 55 model (with a13×55 mm profile) is a roller shutter made with two-component PVC+ALUMINUM slats featuring high-density insulation, which, by breaking the thermal bridge, provide enhanced thermal insulation for the shutter.  This type of two-tone roller shutter allows you to choose different colors for the inner and outer sides of the slat, better adapting to both the interior decor and any color requirements of the exterior facade. 

The Duero line includes the Duero 40model , which is suitable for small spaces thanks to the lower wrap created by the9×40 mm slat.
