Gets the job done
Would RecommendI have 3 odd shaped windows on a 20 ft south facing wall in a room with a cathedral ceiling. Awesome greenhouse effect in winter, absolutely BRUTAL in the summer. I cut these to fit the odd window shapes, wrapped in batting and covered with a white fabric. Inserted into the recessed windows to cover and they significantly help us not get cooked in the summer.
