Particularities of the 5Stars Invisible Aluminium Windows

• 5Stars Invisible aluminium windows have a hidden sash, thinner profiles and are characterized by a section of only 66 mm visible from the exterior
• The hidden sash maximizes the glazed area, being possible to reach up to 85% of the total surface area of the window
• Due to the fact that it allows a larger glazed area, 5Stars Invisible system provides an extraordinary light gain in the inner rooms.
• They allow the use of hidden hinges that make possible the 180 degrees opening and the use of the “invisible” front handle, embedded in the side sash
