Window Opening Control Devices (WOCDs) are specialised window hardware that can be installed on operable windows that are designated as emergency escape and rescue openings.
The most obvious indication of failure of an installed insulating glass (IG) unit in a window or door is permanent visual obstruction due to a milky-white fog or film on the interior surfaces of the glass (surface numbers two or three in dual-pane IG) due to moisture or chemical deposition.
In 27 EU Member States (out of 28) minimum requirements for windows have been introduced. These requirements can be regrouped in three categories: minimum requirements based on the U-value (being Uwvalue or Ug-value), on the Uw-value and g-value separately or on the energy balance combining both the Uw-value and g-value.
The climate crisis is all too real, prompting more than 230 medical journals to warn that 1.5 degrees Celsius of global warming above pre-industrial levels risks “catastrophic harm to human health that will be impossible to reverse” and call on governments to respond with “unprecedented funding.”
