Key Features: Arctic Tern Flat Window - 300x700mm

Blind and screen are included with each window and come with a fine mesh insect screen and a blackout blind with a reflective exterior. The cover panel contains the retractable fine mesh insect screen on one side & a blackout blind with a reflective exterior on the other. These can be used independently, or together for varying combinations of privacy and ventilation. The blind also creates a second dead air space for maximum thermal efficiency in very cold conditions.

Tern Overland windows are designed to have excellent thermal insulation to keep the interior of your build comfortable in all seasons by helping regulate temperatures & minimize energy consumption.

Even with all these features, these windows weigh barely 60% of a similarly sized glass window. Lastly, some of these windows can even serve as an emergency exit.

The Arctic Tern Classic Window features a lighter tint with a classic domed exterior, while the Arctic Tern Flat window has a darker tint and features a contemporary flat exterior.

Both Classic & Flat Arctic Tern windows come complete with the blind & screen assembly.

Blind & Screen assemblies come in either a polar white or a sleek black finish.

These windows are warrantied by Tern Overland LLC for one year against defects in workmanship and materials. We have a complete in-house parts & service department.
