A screen assembly is disposed in a frame opening of a building. The screen assembly includes a first rail bounding one side of the frame opening and a second rail spaced from and fixed relative to the first rail bounding an opposite side of the frame opening. A first guide is adjustably coupled to the first rail and a second guide extends from the second rail. The screen assembly includes a screen apparatus having a screen and a slide component coupled to the screen. The slide component slides along the first and second guides for extending the screen across the frame opening. The location of the first guide may be adjusted relative to the first rail to align the first and second guides thereby allowing the slide component to freely slide along the guides.
