The Crystal Double Glazed uPVC Window is an ideal solution for homeowners looking to improve thermal efficiency and security without compromising on style. This unit is perfectly suited for rooms requiring a balance of natural light and airflow, offering an A-rated energy performance that helps reduce heat loss. While it provides excellent insulation through its argon-filled double glazing, please note that it is designed as a fixed-combination side-hung unit, meaning the ventilation is limited to the side-hung section and the integrated trickle vent system.

An A-rating indicates the highest level of energy efficiency, meaning the window is highly effective at retaining heat and preventing energy loss.
The night vent is designed to provide minimal airflow while the window remains in a locked position; however, it is always best practice to fully close and lock windows when leaving the property unattended for extended periods.
The trickle vent allows for continuous background ventilation, which helps reduce humidity and condensation buildup within the room.
Yes, every unit is supplied with a white handle.
Wipe the frames down with a soft cloth and soapy water; avoid solvents or abrasive sponges.
Yes, the 28mm Low E double-glazed units come pre-installed.
Check the hinges for obstructions or debris and apply a light silicone lubricant to the moving parts.
Verify that the multi-point lock is fully engaged and check that the window is correctly compressed against the rubber seals.
Remove the handle cover cap to access and tighten the mounting screws.
Installation should be carried out by a qualified professional to ensure the frame is level, plumb, and square for weatherproofing. The unit includes a PVC cill that must be installed underneath the frame to direct rainwater away from the building exterior. When installing, use the provided glazing packers to ensure the glass unit is correctly positioned within the frame, which prevents sagging and ensures smooth operation of the side-hung hinge.
To care for your uPVC window, clean the frames regularly using a soft cloth and mild soapy water—avoid abrasive cleaners that could scratch the finish. Lubricate the metal components of the espag locking system once a year with a silicone-based spray to maintain smooth operation.
