A window with an electric actuator holds the sash firmly in position. However, it is not automatically as tight and burglar-resistant as a window with a locked fitting. Whether that is enough depends on where the window is located. This guide explains what matters for tightness, burglary protection and power failure, and when an additional locking actuator makes sense.<\/p>\n\n\n\n
In brief:<\/strong> A window actuator holds the sash in position but does not replace a lock. For skylights, roof windows and high-level windows the actuator alone is usually sufficient. For reachable windows, for example on the ground floor, an additional locking actuator such as the VS-VA 600 is recommended for better tightness and burglary resistance.<\/p>\n\n\n When closing, the actuator pulls the sash into the seal with its pulling force. For small and medium sashes, this usually provides good tightness. For large sashes, however, the actuator presses the sash at only one point. The seal may then be pressed less firmly at the corners.<\/p>\n\n\n The solution is a Locking drive VS-VA 600<\/a>. It is combined with the chain or spindle actuator and locks the sash via the fitting after closing. This improves tightness and increases burglar resistance. For wide sashes, two synchronised actuators also help, see tandem operation<\/a>.<\/p>\n\n\n An actuator holds the window in the position it is in. However, it does not replace a lock. What matters is whether the window can be reached from outside:<\/p>\n\n\nIs a window with an actuator tight?<\/h2>\n\n\n
