Crystal Black and White LH Side Hung Next to a Fixed Clear Triple Glazed Window 905 x 965mm - Black

'LH' stands for Left Hand. This indicates that the opening casement (the part that swings open) is hinged on the left side when viewed from the outside of the property.

The U-value of this window is 1.0 W/m2K, indicating excellent thermal insulation performance.

Trickle vents are small, adjustable openings typically located at the top of the window frame. They allow a controlled amount of fresh air to enter the room continuously, reducing condensation and improving air quality without significant heat loss or security compromise.

Yes, the white handle is designed to be replaceable. Standard window handles can usually be unscrewed and replaced. Ensure you obtain a compatible handle if a replacement is needed.

Yes, the overall product height of 965mm includes the PVC cill.

PVCu frames are very low maintenance. Regular cleaning with a damp cloth and mild soap is usually sufficient. Avoid harsh chemicals or abrasive materials.

Clean the glass surfaces with a soft, damp cloth and a standard glass cleaner. For the gaps between panes (if accessible externally), use a damp cloth. Ensure any cleaning agents used are suitable for glass and seals.

Check for obstructions around the frame and sash. Ensure the espag locking mechanism is fully disengaged. The window may require minor adjustment by a professional installer if warped.

Slight condensation on the external surface in cold weather is normal for high-performance glazing. Internal condensation may indicate high humidity levels in the room; use trickle vents and ensure adequate room ventilation. If condensation appears between the glass panes, the seal may be compromised, and the unit may need replacement.

Ensure there are no obstructions. Lubricate the espag mechanism with a silicone-based lubricant. If the issue persists, check for frame movement or misalignment.

Check that the window is fully closed and locked. Inspect the weather seals for damage or wear and replace if necessary. Ensure the window was installed correctly with a proper seal against the building fabric.
