Function

Air is supplied or extracted through the horizontal blades. The design of the grille prevents rainwater from reaching the ductwork. The slot between the frame and the top blade is sealed, thus preventing rainwater from entering the ductwork from above. Drops of water are collected in the grooves at the front edge of the blades. Water flows to the side grooves, where it drops down.

Traditional outdoor louvre

Rain falling on the vane flows downwards to the front edge of the vane. Drops formed at the edge fall down on the vane below, and upon contact with the vane surface break into small droplets and spray which are easily moved by the air flow through the louvre. Water flowing along the wall onto the louvre penetrates the slot between the frame and the top vane unless the slot has been closed.

USM blade construction
The vanes of the USM louvre are designed to collect the droplets in grooves at the front edge of the vanes. Once the slot between the frame and the top vane has been securely closed, water flowing down the wall will not enter the louvre. The top vane directs the water to the side grooves, along which the which the water flows down past the air flow.
