Arctic Tern Double-Pane RV Window (300x500mm) by Tern Overland

In Europe, almost all camper vans and motorhomes use Dometic Seitz-style double-pane RV windows. This Arctic Tern Double-Pane RV Window (300x500mm) has many advantages over typical glass camper van windows and the Seitz windows, including the following: Windows are double-glazed and include an integrated day/night shade, providing much better thermal performance than single-pane glass for keeping warmth in and heat out as needed Integrated day/night shade and screen is a much more versatile window covering than curtains, blinds or magnetic window coverings Entire pane of the window swings out on gas struts, and can be clicked into place at angles of 20, 40 and 60 degrees. The Lucite acrylic double-glazing makes for a window assembly that weighs 40% less than a similarly-sized single-pane glass RV window Windows have many positions including fully-open (at 20-60 degrees), fully-locked, and half-locked. In half-lock position, windows provide ventilation, and are secure enough to drive.
