People enjoy large, clear glazed windows as they let daylight in and allow us to maintain contact with the outdoor environment. During colder months even well-insulated modern windows become the weakest link in the overall façade insulation and are responsible for the largest heat loss. During the day, shading in a raised position can assist in letting the daylight in and maximise the heat gain. And at night, shutters and smart shading in a closed position improve the window’s insulating properties and assist in keeping the valuable heat in.
At night solar shading in extended position provides extra insulation helping to prevent heat losses.
During the day solar shading in retracted position lets free solar energy indoors, therefore reducing energy use for heating.
