A-rated signifies high energy efficiency. For windows, it typically relates to a low U-value, meaning less heat escapes from your home, contributing to lower energy bills and a more comfortable environment.
The overall U-Value for this window is 1.4 W/m2K, which is a measure of heat transfer. A lower U-value indicates better insulation.
While the window comes with essential parts like a cill and packers, professional installation is highly recommended to ensure proper sealing, security, and optimal thermal performance, as well as to comply with building regulations.
The Low E glass can be cleaned using the same method as standard glass: a soft, damp cloth with mild soap and water. Avoid abrasive cleaners.
Trickle ventilation provides a controlled, continuous supply of fresh air into the room, helping to reduce condensation and improve indoor air quality without compromising security or significantly impacting thermal performance.
Espagnolette locking (espag locking) is a multi-point locking system operated by a single handle. It offers enhanced security by engaging multiple locking points along the edge of the window sash.
The dimensions of 1190 x 1040mm are the overall height and width, including the included PVC cill.
Check for any obstructions in the opening mechanism or frame. Ensure the espag locking handle is fully disengaged. If the issue persists, the hinges or locking mechanism might need adjustment by a professional.
This is unlikely for a new double-glazed unit and may indicate a seal failure. Contact the supplier or installer. If condensation is between the panes, the unit has failed and requires replacement.
Ensure the window is correctly sealed within the frame and that all locking points are engaged. Check the condition of the seals around the opening. Professional installation is key to preventing drafts.
Clean and lubricate the espag mechanism with a silicone-based lubricant. Ensure no debris is present in the keeps on the frame. If the problem continues, the mechanism may be damaged and require replacement.
Setup: This window is designed for straightforward installation, especially with the included PVC cill and glazing packers. Ensure that the opening is correctly measured to accommodate the window unit and cill. Professional installation is recommended to ensure proper sealing, security, and optimal thermal performance. The espag locking mechanism and handles should be checked for smooth operation after installation.
Compatibility: The window is a standard PVCu construction, making it compatible with most common building materials. Its black finish offers versatility in matching exterior aesthetics. Always verify that the 1190 x 1040mm dimensions (including cill) fit your intended opening.
Care: To maintain the appearance and functionality of your window, regular cleaning is advised. Use a soft, damp cloth with mild soap and water for the frame and glass. Avoid abrasive cleaners or solvents, which can damage the PVCu and glass surfaces. Wipe down the espag locking mechanism and any moving parts periodically with a silicone-based lubricant to ensure smooth operation. Check seals for wear and tear annually.
