Arctic Tern Windows
Our windows are designed for adventurers who demand strength, performance, and reliability—combining cutting-edge materials, innovative design, and rugged construction.
UNMATCHED QUALITY AND DESIGN
Every Arctic Tern Window is built from premium, globally sourced components. Crafted from genuine G.E. Lucite Perspex, our dual-pane European acrylic maintains exceptional clarity even after 10 years of full sun exposure.
A top-tier powder coating ensures enduring protection against the elements, while precise assembly meets strict European ECE regulations and is DOT-certified for North America. Select sizes can even serve as emergency exits.
CLASSIC & FLAT WINDOW OPTIONS
Choose between our Classic and Flat designs to match your build style.
- Classic: Bright, open interior with a raised profile
- Flat: Sleek, modern exterior with dark gray tint for privacy and glare control
Both options include the integrated blind and screen system.
INTEGRATED BLIND & SCREEN SYSTEM
Each window includes a dual-function assembly available in white or black:
- Fine mesh insect screen
- Blackout blind with reflective exterior
These can be used independently or together, creating a second dead air space for enhanced thermal insulation in cold conditions.
