Crystal Double Glazed Window - White

A Rated glazing is the highest energy efficiency rating for windows. It means the window is designed to minimize heat loss and gain, helping to keep your home warmer in winter and cooler in summer, potentially reducing your energy bills.

An espagnolette (espag) locking system uses rotating steel bolts that slide into keeps (striker plates) on the window frame. Turning the handle operates these bolts, securing the sash to the frame at multiple points for enhanced security and weatherproofing. It also typically allows for a 'night vent' position.

Trickle ventilation is a small, controllable opening, often integrated into the window frame, that allows a continuous flow of fresh air into the room even when the window is closed. This helps to reduce condensation and improve indoor air quality without significantly impacting security or heat loss.

This window has specific dimensions of 610 x 610mm. It is suitable for openings that match these measurements. Compatibility depends on the size of your existing opening or the design of your new construction.

Glazing packers are small shims or wedges, typically made of plastic or composite materials, used during window installation. They are placed between the glass unit and the window frame to ensure the glass is correctly supported, centered, and held securely, which is crucial for the longevity and performance of the glazing.

All product handings for this window are viewed from the outside. A top-hung opener will have hinges at the top and the opening mechanism at the bottom of the sash when viewed externally.

The white handle is typically secured with screws. While it can be removed for cleaning or replacement, it is designed to be a functional part of the locking mechanism and should be reattached securely.

Check for obstructions around the frame or sash. Ensure the espag locking mechanism is fully disengaged. Clean and lubricate the moving parts of the locking system.

Clean the espag bolts and keep them lubricated. Check that the keep (striker plate) on the frame is aligned correctly with the bolts. Ensure there is no frame distortion preventing proper engagement.

While double glazing reduces internal condensation, it can still occur if indoor humidity is very high. Ensure trickle vents are open and functioning. Use extractor fans in kitchens and bathrooms. If condensation is between the panes, the seal may be broken, requiring professional assessment.

Check that the window is fully closed and the espag lock is engaged correctly. Inspect the weather seals around the frame and sash for damage or gaps. Ensure glazing packers are correctly fitted and the window is properly sealed into the building opening.
