Crystal LH Side Hung Obscure Double Glazed Window 610 x 1040mm - Agate and White

LH stands for Left Hand. 'Side Hung' means the window opens outwards from the top on hinges located on the left side of the frame when viewed from the inside.

The U-value measures how effectively a window prevents heat transfer. A lower U-value (like the 1.4 W/m2K of this window) indicates better insulation, meaning less heat escapes, leading to energy savings and improved comfort.

While installation is designed to be straightforward with included accessories, professional installation is recommended to ensure correct fitting, sealing, and optimal performance and security.

Use a soft, damp cloth with mild soap if necessary. Rinse with clean water and dry with a lint-free cloth. Avoid harsh chemicals or abrasive materials.

The night vent option allows the window to be locked in a slightly open position, providing secure ventilation without compromising safety.

This window comes with a white-finished handle designed for the espagnolette locking system.

The glass is 'obscure', meaning it distorts views and provides privacy while still allowing light to pass through. It is not completely opaque.

Check for any obstructions around the frame or sash. Ensure the handle is fully engaged and disengaged. The locking mechanism might need lubrication.

This indicates a failure of the sealed unit, which is typically covered under warranty. Contact the supplier for a replacement.

Apply a silicone-based lubricant to the espagnolette bolts and the gearbox. Operate the handle multiple times to distribute the lubricant.

Check that the window is properly sealed against the frame and that any existing sealant is intact. Ensure the glazing packers are correctly positioned and the unit is securely fitted.
