European Dual Action Windows (also known as Tilt and Turn Windows) are an innovative window design that offers versatile functionality through a single handle mechanism. Unlike traditional windows that open in only one way (such as sliding or casement), European Dual Action Windows feature a sash that can operate in multiple ways depending on the model and configuration.
These windows are constructed with insulated glass units (IGUs) that consist of two or more glass panes separated by gas-filled spaces. These spaces are maintained by window spacers – critical components that create the precise gap between glass panes while providing a moisture-proof seal at the edges. Spacers can be made of aluminum, stainless steel, or “warm edge” materials that reduce thermal conductivity and minimize condensation.
These windows are available in Single, Double, Triple and even more sash models, providing flexibility for different architectural needs and styles. Their operation includes several modes:
Turn: The sash swings open completely like a door for maximum ventilation and easy cleaning
Tilt: The sash tilts inward from the top for secure ventilation
Micro Tilt: A minimal tilt position for subtle air exchange
These operating modes are available in various permutations and combinations depending on the window model and hardware specifications.
The primary benefits of European Dual Action Windows include exceptional energy efficiency due to their airtight seals when closed, versatile ventilation options, enhanced security with multi-point locking systems, and improved sound insulation.
These windows are typically constructed with durable materials like vinyl, aluminum, or wood, and feature sophisticated hardware mechanisms that support their multiple opening functions while maintaining structural integrity.
