Inner curtain in Sanaa's Museum in Toledo, Ohio 
Sanaa designed a large air space in façade that sketches the curve envelope of the building. Curved glasses (laminated on the outer layer and tempered on the inner) draw the large chamber of variable width. This gallery is heated to form a true "neutralizing wall." From the inside space, the view is a radical transparent continuity thanks to the renounce of double glass.In large sections of the gallery, there is a sliding curtain as solar protection. Besides protecting with its reflection, it provides privacy and a diffuse lighting of interior space.
