How Well Do Plantation Shutters Insulate?

A shutter creates an additional layer between the room and the glazed window, which can help reduce heat transfer when the panels and louvres are closed.

How the extra layer helps

The shutter does not replace insulated glazing, but the panel and the air space between the shutter and glass can reduce direct air movement and radiant heat exchange at the window.

Fit affects performance

A neat fit around the opening helps. Large gaps, an unsuitable frame or panels that do not close correctly reduce the benefit of the additional layer.

Use shutters with the season

Close shutters during periods of strong summer sun or on cold nights, then open them when you want solar warmth, daylight or airflow. The benefit depends on the window, room and climate.
