Effortless cleaning

Nobody likes to spend a lot of time cleaning and maintaining their windows and doors. That’s why we have designed our systems for heavy use while withstanding the wearing effects of long-term exposure to the elements and years of repeated opening and closing.

HDF (High-Definition Finish) Surfaces Wipe Clean With Water
​Our windows and doors feature an especially smooth surface with a sophisticated sheen. Dirt and dust are less likely to cling to the surface, and cleaning is effortless. Simply use water and a cloth.

Minimal Maintenance Required
​Once a year, simply lubricate the movable components with a drop of cooking oil (e.g. vegetable oil).

The windows remain as clean as snow for many years without the need for tiring cleaning!
