Tandem & Grid Skylight

tandem-drawingPre-glazed modular units are custom fabricated to the size and design requirements of the job- producing a custom skylight with remarkable economy. The basic module is the tandem unit, consisting of multiple acrylic domes or pyramids in a single frame and shipped as a unit. The tandem minimizes and simplifies on-site labor. Plasteco must be consulted in the planning stages to determine unit sizes and mullion arrangement.
