Can I block off a sunroom window with drywall or something similar?

Hi, yes you can block off a sunroom window with drywall or other similar materials by either permanently installing a new wall section or by using temporary coverings. For a permanent solution, drywall can be installed over the window, which is then taped, mudded, and painted to match the surrounding walls.

Yes, you can. For a temporary fix, cover the window with rigid foam insulation and finish it with drywall or thin plywood. If you want a cleaner look, build a light stud frame, add insulation and a vapor barrier, then cover it with drywall. Just make sure to leave a small gap between the glass and the new wall to prevent condensation or mold.

You can block the view from the inside by building a temporary 2x4 wood stud wall lined with Rockwool insulation and finished with drywall. To prevent hidden mold, you must leave a 1-inch air gap between the sunroom glass and the new frame so condensation can safely evaporate. Before adding the insulation, line the windows with black landscape fabric to create a clean "blackout" appearance from the outside yard.

Yes, it is possible to temporarily cover a window from the interior, but drywall alone is usually not the best option if the window will remain in place for an extended period. Many homeowners choose to use an insulated panel or frame out the opening with insulation and drywall on the interior side while leaving the exterior window intact. This can improve appearance and help with temperature control. The main consideration is moisture — if the window is completely sealed off without allowing for airflow or proper detailing, condensation can develop inside the enclosed space over time. If this is intended as a temporary solution until a larger renovation takes place, it may be worth discussing the plan with a contractor to ensure it can be easily reversed and won't create moisture issues down the road. — Ainger Group Roofing and Exteriors
