FAQs
What does 'A Rated' mean for this window?
A-Rated signifies excellent energy efficiency. This window achieves a U-value of 1.0 W/m²K, meaning it minimizes heat transfer, keeping your home warmer in winter and cooler in summer, thereby reducing energy consumption.
How do I know which way the window opens?
The product description states that the image shows the product viewed from the outside and it is a top-opener. This means the vent opens outwards from the top hinge.
What is trickle ventilation?
Trickle ventilation provides a small, controlled amount of airflow into the room even when the window is closed and locked. It helps to improve air quality and reduce condensation without compromising security or thermal performance.
Can I install this window myself?
While basic DIYers might attempt installation, professional fitting is strongly recommended. Proper installation is crucial for ensuring the window's energy efficiency, security, and longevity, and to prevent potential issues like drafts or water ingress.
What is the warranty period?
The window comes with a 10-year manufacturer's warranty, subject to terms and conditions.
What does 'Espag locking' mean?
Espagnolette (Espag) locking is a multi-point locking system that secures the window sash to the frame at various points using a central mechanism operated by a single handle. It offers enhanced security and allows for a night vent position.
Is the cill included in the dimensions?
Yes, the product height includes a 30mm allowance for the included PVC cill.
Troubleshooting
Window is difficult to open or close
Check that the espag locking mechanism is fully disengaged. Ensure no obstructions are present. If persistent, the window may require adjustment by a professional.
Condensation appearing on the glass
Minor condensation between panes may indicate a seal failure and require replacement. Condensation on the *inside* surface is usually due to high indoor humidity; use trickle vents and/or reduce moisture sources.
Locking mechanism feels stiff
Clean the locking mechanism with a damp cloth and apply a silicone-based lubricant to moving parts. Ensure the sash is correctly aligned before locking.
Drafts around the window edges
Check the integrity of the window seal against the frame and the wall. Ensure all locking points are engaged. Professional assessment may be needed if drafts persist.
Improved indoor air quality via trickle ventilation.
Modern aesthetic with dual colour options.
Cons
Product height includes a 30mm cill, requiring careful measurement.
Triple glazing may add slight weight compared to double glazing.
Outward opening vent style may be unsuitable for very tight exterior spaces.
Professional installation is recommended for optimal performance.
