HUECK Lambda WS 075 VS

-Ventilation flap with 75 mm basic depth
-Optimum ventilation through room-high sashes for rapid air exchange
-Thermal insulation: Uf ≥ 1.2 W/m²K

The HUECK Lambda WS 075 VS and WS 075 IS VS ventilation flaps create a clear opening due to the minimal face widths, which creates a large ventilation cross-section while also offering advantages in terms of burglar resistance and fall protection when used in conjunction with a single cavity window, in the window strip, or clamped in the façade. The intelligent construction approach makes it very simple to implement object solutions with larger face widths.
