Crystal Top Hung Opener Double Glazed Window - Black

The window features an A-rated glazing unit, signifying high energy efficiency.

It uses an espag locking system, which offers security and the option for secure night vent positions.

The window is supplied with a white handle, PVC cill, and glazing packers to aid installation. Professional installation is recommended.

The window measures 440mm in width and 610mm in height. The overall height includes the cill.

Clean the PVCu frame with a soft, damp cloth and mild soapy water. Avoid abrasive cleaners.

Trickle ventilation provides a small, continuous flow of fresh air into the room, helping to maintain air quality and reduce condensation without significant heat loss.

This window has a specific size of 440 x 610mm and is best suited for openings that precisely match these dimensions. Professional assessment of the opening is advised.

Check for obstructions in the opening mechanism. Ensure the espag locking system is fully disengaged. The frame may have shifted slightly; professional adjustment might be required.

Ensure trickle vents are open and not blocked. Increase ventilation in the room and check for sources of high humidity. Condensation on the *outside* of the glass is normal and indicates good insulation.

Clean the locking points and mechanism. Apply a small amount of silicone lubricant. Ensure the window is properly aligned before attempting to lock.

Check the seals around the frame. Ensure the window was installed correctly and the frame is sealed to the wall. Professional recalibration or resealing may be necessary.
