Triangle – system component for wood-aluminium window systems

Improve water drainage at the sash frame

The BUG Triangle system element is a functional component. Inclined profile contours in the lower area of ​​the sash frame support water drainage while reducing the water level in front of the glass pane and the seal on the aluminium profile.

Slimline profile component with a big impact

The profile element enables a combination of angular and sloped or rounded profile systems. This creates a unique appearance. But more importantly, the system component offers a key advantage: once the slimline element is integrated into the frame construction, it facilitates rainwater drainage even when the window is tilted, reducing moss formation on the seals.

The most important questions about the BUG Triangle system component

The BUG Triangle system element is a new type of aluminium component – ​​a profile in a rounded triangle shape – which is installed with the angular profile system of the window. Due to the variable combination of the Triangle element, it can be used on all sides of the window profile. This opens up countless design possibilities for an attractive facade silhouette.

The sash profile, bevelled by the BUG Triangle, supports the drainage of rainwater – even when the window is tilted. This prevents water from accumulating and from penetrating to the inside when the sash is opened. Dirt is also prevented and window maintenance is made considerably easier. In this way, the BUG Triangle also supports window water drainage.
