The Crystal Double Glazed Window (610 x 1040mm) is ideal for homeowners looking to improve thermal insulation and interior comfort in medium-sized room openings. It offers superior energy efficiency through its A-rated design and argon-filled glazing, making it a reliable choice for long-term energy savings; however, users should ensure the dimensions strictly match their rough opening as the unit is non-adjustable once installed.

A-Rating indicates the highest standard of energy efficiency, meaning the window is highly effective at retaining heat and reducing energy costs.
Yes, a matching white handle is included in the package.
While technically possible for experienced DIYers, professional installation is recommended to ensure a proper airtight seal and warranty compliance.
The night vent allows the window to be locked in a slightly open position, providing ventilation while maintaining a level of security.
Clean the frames with warm soapy water and a non-abrasive cloth. Avoid solvent-based cleaners that could damage the finish.
Check for debris in the track or hinges; ensure the frame is not twisted due to improper shimming.
Verify that the espag lock is fully engaging and inspect the rubber weather seals for damage or compression issues.
Remove the handle screw cover and tighten the mounting bolts using a screwdriver.
Installation should be performed by a qualified window fitter to ensure the frame is perfectly square and sealed to the brickwork using expanding foam or suitable sealant. Ensure the rough opening is approximately 10mm wider and taller than the unit dimensions to account for shimming. To maintain the window, clean the PVC frames with a soft cloth and mild soapy water, avoiding abrasive chemicals. Periodically check the locking mechanism and hinges for debris and apply a light silicone-based lubricant once a year to keep operation smooth.
