SKI. The aluminum window for your adventure.

The extrem window SKI is a very high quality aluminum window for touring vehicles, expedition vehicles, overland trucks, camper vans and many other vehicles.

SKI has a super strong sash and frame made of insulated, thermally separated aluminum profiles.

Fantastic views are made possible by the thermal insulation glazing made of safety glass with road approval, which is suitable for all heights.

High-quality stainless steel scissor hinges guarantee easy and stepless opening.

The windows have a multiple locking system and a flat, ergonomic aluminum handle.


Frame and sash are made of high quality 6060 aluminum profile. Optionally powder coated in RAL colors or anodized. The profiles are thermally separated throughout by glass fiber reinforced insulators.


Extremely strong construction with solid frame and very robust window sash. All seals are triple, continuous all around and made of synthetic rubber EPDM. High quality fittings and locks make SKI perfect.


Genuine safety glass is combined to form thermal insulation glazing. The specially made for our window SKI panes are with European Traffic Approval (ECE R43) and DOT. A solar control coating is available as an option.
