Crystal Double Glazed Window - Black

'LH' stands for Left Hand, and 'Side Hung' means the window opens outwards from hinges on the left side when viewed from the exterior.

The U value measures how well a window prevents heat loss. A lower U value, like the 1.4 W/m2K of this window, indicates better insulation and energy efficiency, helping to keep your home warmer and reduce heating costs.

Use a soft, damp cloth with a mild soap solution. Rinse with clean water and dry with a soft cloth. Avoid using harsh chemicals or abrasive scouring pads, as these can damage the finish.

The night vent position allows the window to be locked open slightly, providing secure ventilation while maintaining a degree of security and keeping out light rain.

Please refer to the product's warranty documentation for specific details on guarantee periods and coverage.

While installation accessories are provided, windows are structural elements. Professional installation is highly recommended to ensure proper fitting, sealing, security, and compliance with building regulations.

Obscure glazing has a frosted or textured finish that obscures the view through the glass while still allowing light to pass. It is ideal for maintaining privacy in areas like bathrooms or ground-floor windows.

Check for obstructions around the frame or sash. Ensure the espag locking system is fully disengaged. If binding persists, professional adjustment may be needed.

This is typically due to high humidity within the room. Increase ventilation using the trickle vents or by opening the window. Ensure no leaks around the frame.

This indicates a seal failure in the double-glazed unit. The unit may need to be replaced by a professional.

Ensure the mechanism is clean and free of debris. Lubricate the moving parts with a silicone-based lubricant. Check for any frame movement that might be misaligning the lock.

Gently clean the vent with a brush or vacuum cleaner to remove dust and debris, ensuring unrestricted airflow.
