uPVC windows are considered safe because of their multi-point, high-security locks. The locks are generally fitted into the core steel portion of the window frame making the UPVC windows air-tight. Not only are they challenging to break, they also enhance sound insulation as well as thermal insulation in homes.
Additionally, the uPVC is naturally a fire-retardant material . In case of a fire accident, unlike wood, it will not act as fuel to the fire.
A uPVC windows manufacturer normally integrates double glazed glasses. You can further use security systems like intruder alarms to increase the safety aspects of your windows.
