The E-Class Skywindow by Wasco Products Inc., Sanford, Maine, needs no mastic, no step flashing and no sealant. The product comes in both venting and fixed models, and features the company’s patented Ultraseal flange. Both the venting and fixed glass models are available in a variety of sizes as well as custom sizes. The venting model can be ordered with an electronic, switch-operated motor and rain sensor, so that the window will close automatically if it is raining.
