Yes, shutters are an excellent way to insulate your windows and improve the energy efficiency of your home. They fit snugly at your window, helping to reduce draughts that can slip through the gaps in your frames by providing a barrier at your window that keeps the cold out and the warmth in. We worked with the experts at Salford University to understand how our products can help prevent heat loss. The results from their specially created lab, the 'Energy House' showed that our shutters reduce heat loss by 36%. In the months of summer, shutters are great for keeping rooms cool too. Tilt the louvres closed when the sun is at its hottest to keep your space at a comfortable temperature.
