Shutters are excellent at reducing heat loss in the Winter. They don’t not only increase the value of your home but also act as an additional layer of insulation for your home. Most heat is lost through your windows and with Plantation Shutters in your home your heating systems won’t have to work as hard to keep your rooms cosy and warmer. They are the most energy efficient window covering as the frame covers the whole of the window and when the louvres are closed no heat can escape. By simply adjusting louvres, you might be able to put on the heating a lot later. In this SEAI energy saving report(link provided) they conclude that Shutters are the best way to reduce heat loss in the evenings. https://www.seai.ie/publications/Energy_Efficiency_in_Traditional_Buildings.pdf
