This refers to the different ways the window can open. 'LH' typically means Left Hand, 'RH' means Right Hand, indicating side-hung openings. 'Top Centre' indicates an opening casement hinged at the top, opening outwards from the center. This offers multiple ventilation configurations.
The U Value of this window is 1.4 W/m2K, which is considered excellent for energy efficiency and helps reduce heat loss.
While the window comes with necessary components for installation, professional fitting is highly recommended to ensure a proper seal, optimal performance, and to avoid issues with drafts or moisture ingress.
The night vent function allows you to lock the window in a slightly open position, providing secure ventilation. Consult the specific locking mechanism instructions provided with the window for exact operation.
Please refer to the product's warranty information provided by Crystal for the specific warranty period and terms.
Modern PVC frames are designed for durability and UV resistance. However, prolonged exposure to intense sunlight can eventually cause fading. Regular cleaning helps maintain its appearance.
Check for any obstructions around the frame or sash. Ensure the espag locking mechanism is fully disengaged. The frame may have shifted slightly; this could require adjustment by a professional installer.
Condensation trapped between the double-glazed units indicates a seal failure. The sealed unit will need to be replaced by a professional.
Check that the espag lock is fully engaged and the window is properly closed. Inspect the seals and weatherstripping for damage. If leaks persist, professional adjustment or resealing may be required.
Ensure the screws securing the handle are tight. If the mechanism feels stiff, clean and lubricate the espag mechanism with a silicone-based lubricant.
Setup: This window is designed for straightforward installation, coming with a handle, PVC cill, and all necessary glazing packers. However, due to the nature of window installation and the importance of achieving a proper seal for energy efficiency and weatherproofing, professional fitting is strongly recommended. Ensure the opening is correctly prepared and the frame is plumb and level before securing.
Compatibility: This window is a fixed size (1770 x 965mm). Compatibility depends on the dimensions of your existing window opening. Ensure the rough opening is suitable for this unit's dimensions, allowing for appropriate reveals and sealing.
