Protective shrouds for temporarily protecting window assemblies, bathroom fixtures, and diverse prefabricated modules used in construction. The shrouds are fabricated from translucent plastic sheet material of polypropylene or polyethylene. A lower open port is selectively blocked by a foldable ventilation panel held in a deployed state by magnets. Rear mounted adhesive strips affix the shroud to the window. Top and side strips are bifurcated to enable rapid adjustments in height and length. When the tear away strips are removed, the exposed adhesive surface is pressed upon the target structure. Slight dimensional adjustments are made by pinching the sheet together, forming creases aligned with strip bifurcations, to gather material and shorten the shroud length or width. During subsequent dry-walling, shroud edges are captivated by wall board segments. Afterwards, the exposed junction between covered shroud and adjacent sheet rock portions is cut, and the shroud is torn away and discarded.
