FAQs
What is the U-value of this window?
The U-value of this window is 1.4 W/m²K, indicating good thermal performance.
How do I determine the handing (left or right) of the window?
All product handings are viewed from the outside. This window is designed for right-hand opening when viewed from the exterior.
What does 'night vent position' mean?
The night vent position allows the window to be opened slightly (usually via a specific lock setting) while still being secured, providing ventilation without significant security compromise.
Is the PVC cill pre-attached?
The product information states that the PVC cill is included, suggesting it may need to be attached during installation.
Can I replace just the glazing unit if it fails?
While possible, replacing a double-glazed unit within a PVCu frame typically requires specialized tools and knowledge. Often, it is more practical to replace the entire window unit if the sealed glazing fails.
What maintenance is required for the espag locking system?
Periodically check the locking mechanism for smooth operation. Lubricate moving parts with a silicone-based lubricant annually or as needed to prevent sticking and ensure longevity.
What type of Low-E glass is used?
The window features Low-E (Low Emissivity) glass as part of its high-performance A-rated glazing unit. Specific technical details of the coating are proprietary but designed for enhanced thermal insulation.
Troubleshooting
Window is difficult to open or close
Check for obstructions around the frame or sash. Ensure the window is properly installed and plumb. The espag locking mechanism may need lubrication. If the issue persists, check if the frame has warped or if the hinges need adjustment.
Condensation on the glass
Minor condensation on the *outside* of the glass, especially in humid conditions, is normal due to the insulating properties. Significant condensation *between* the panes indicates a seal failure, and the unit may need replacing. Condensation on the *inside* usually points to high indoor humidity; ensure adequate ventilation.
Espag lock not engaging properly
Ensure the window is fully closed and aligned. Check that the keeps on the frame are correctly positioned. The locking mechanism may require adjustment or lubrication.
Drafts or air leaks
Inspect the weather seals around the opening sash and frame for damage or wear. Ensure the frame is securely installed and sealed to the building fabric. Re-apply sealant if necessary.
