Crystal Double Glazed Window - White

'LH' refers to Left Hung and 'RH' refers to Right Hung. This indicates the direction the window opens and the location of the hinges when viewed from the outside.

The U-Value is 1.4 W/m2K, achieved through the A Rated Low E glass, Argon gas fill, and warm edge spacer bar, indicating good thermal insulation performance.

While the window comes with necessary packers for glazing, professional installation is strongly recommended to ensure proper fit, sealing, and structural integrity. Incorrect installation can lead to performance issues and void warranties.

The night vent function allows you to lock the window in a slightly open position, providing secure ventilation without compromising the security of your home. It's useful for maintaining airflow overnight or when away for short periods.

The white PVC frame can be cleaned with a soft cloth and mild soapy water. Avoid using abrasive cleaners or solvents, as these can damage the surface.

The package includes the double-glazed window unit, a white handle, a PVC cill, and all necessary glazing packers for installation.

Check for obstructions in the locking mechanism. Ensure the window is fully closed. Lubricate the espag bolts with a silicone-based lubricant if necessary. If the issue persists, professional adjustment may be required.

This is often due to high humidity within the home. Increase ventilation by using trickle vents more frequently or opening windows regularly. Ensure extractor fans in kitchens and bathrooms are functional.

Check seals and weatherstripping for damage. Ensure the window is correctly installed and sealed to the building fabric. Small gaps can often be sealed with appropriate fillers or sealant, but significant drafts may indicate an installation issue.

Gently clear any visible debris from the vent opening using a soft brush or vacuum cleaner. Ensure the vent is properly seated within the frame.
