The removable screen for covering a building opening includes elongated channels configured for attachment to building structure defining a large building opening; and a screen member configured for releasable attachment to the elongated channels. The screen member includes a screen panel permitting light and air to pass there through but preventing insects from passing therethrough, and border strips attached to three sides of the perimeter of the screen panel. The border strip is configured to slidably engage the elongated channels to retain the screen member over the garage door opening. An elastic strip is attached along at least one side of the perimeter, and a zipper attached between the border strip and the zipper.
