Awning with Fixed Window
Style: TB 4100

Live large and bring natural illumination into your space with Portella fixed windows. Allow the outdoor light to stretch into any space from a dull stairway to a dark hallway. Or transform a large wall into a breathtaking vista. Choose from a variety of geometric shapes, sizes and colors that are beautiful, airtight and energy efficient. Use them in combination with other Portella windows and doors to create a custom configuration.
