Jul 10, 2011 July 10, 2011 (September 13, 2012) Bob and Carol. Our Philippine House Project Window Screens and Kulambos. Of course we always planned to have screens on the windows and doors of our new house, but we procrastinated. Screens on casement windows are a bit complicated. The window sash open out, so exterior screens wont work. Screen doors can boast plenty of style too. Here, decorative strapwork creates a guarded but attractive boundary between the front door and the street outside. Fresh air filters right through to cool the home, but the hot sun doesnt get very far.
