Crystal Agate and White RH Side Hung and Top Opener Clear Double Glazed Window 1190 x 1190mm - White

This describes the way the window opens. 'RH' means Right Hand, so the main opening hinges are on the right side when viewed from outside. 'Top Opener' means it can also be opened from the top for additional ventilation.

Espag (Espagnolette) locking is a multi-point locking system that secures the window sash into the frame at several points, enhancing security.

Clean both the inside and outside surfaces of the glass with a soft, damp cloth and a mild, non-abrasive cleaner. Avoid abrasive materials that could scratch the glass.

Yes, the window comes complete with a white PVC cill for a finished look and easier installation.

Trickle ventilation provides a small, controlled airflow through vents, usually at the top of the window. It's important for maintaining good indoor air quality and preventing condensation without compromising security.

The U-value measures how effective the window is at preventing heat transfer. A lower U-value, like the one indicated for this window, means better insulation and less heat loss.

While designed for standard openings, it's crucial to have a professional installer assess your wall structure to ensure compatibility and proper sealing for optimal performance and security.

Check for obstructions around the opening mechanism. Ensure the espag locking points are fully disengaged. If the issue persists, the hinges or mechanism may require adjustment by a professional installer.

Inspect the window seals and ensure the frame is properly seated and sealed against the wall opening. Check that the espag locking is fully engaged. Professional inspection may be needed to re-seal the unit.

Gently clear any debris or obstructions from the trickle vent openings using a soft brush or vacuum cleaner attachment.

Minor condensation on the *outside* of the glass is normal, especially in humid conditions. Condensation *between* the panes indicates a seal failure, requiring replacement of the glazing unit.
