Shutters are a work-horse of a window dressing, fulfilling multiple functions, like managing light, providing insulation - both in terms of temperature and noise, and it's easy to overlook who they can be a practical solution too. During summer, large expanses of glass featuring doors and windows can beautifully blur the boundary between outdoors and inside, but they are less engaging in winter. Tracked shutters still allow access to the doors behind them if required, but are turned into an interactive piece of art simply by tilting the louvres on alternate shutters top and bottom for an eye-catching look, not to mention blocking out the wintery weather.
