Micro Ventilation Double Inswing Opening Systems Window

Q1: How does the micro-ventilation function work?
A: The micro-ventilation system operates through a specialized fitting that creates a small, controlled gap (typically 4-6mm) along the perimeter of the window sash. This allows for continuous air exchange, enabling fresh air to enter while stale air and moisture are released. This innovative function, activated by a specific handle position, ensures optimal airflow and energy efficiency without requiring a full tilt or swing.

Q2: What are the primary benefits of using a double-inswing window system?
A: The main advantage is its dual functionality, offering both a subtle micro-ventilation tilt and a full inward swing. This design provides superior control over ventilation and allows for safe and convenient cleaning of the exterior glass from inside the building. The Alumaster system is an ideal solution for projects where exterior clearance is limited.

Q3: Does this window system provide adequate security when in micro-ventilation mode?
A: Yes, the Alumaster micro ventilation double inswing window remains securely locked when in the micro-ventilation position. The mechanism holds the sash firmly in place, preventing unauthorized access while allowing a small gap for air exchange. This feature provides peace of mind for corporate buyers, contractors, and builders, ensuring safety is not compromised for ventilation.

Q4: What is the recommended installation process for Alumaster’s double inswing windows?
A: For optimal performance and security, we recommend a full-frame installation, which involves replacing the entire window unit. Proper installation should include careful preparation of the rough opening, shimming to ensure the frame is level and square, and professional sealing with an airtight, low-expansion foam to prevent air and water leaks.

Q5: How do you maintain and clean the double inswing window system?
A: Cleaning and maintenance are straightforward due to the inward-swing capability. Both sides of the glass can be safely cleaned from inside the building, eliminating the need for ladders or exterior access. Regular inspection of the hardware and seals is recommended to ensure smooth operation and long-term durability.
