The term “cell” describes each side pocket on a honeycomb shade. These pockets create an airspace “barrier” between your window and the room. The more cells, the more energy efficient the shade is. Also, larger cell sizes provide better insulation by trapping air in the pockets, which helps prevent extreme temperature changes in your home.
Thermal draperies not only increase your home’s privacy, they also help save money on monthly A/C bills during warmer months by blocking heat at the window, and help you save on heating in the winter by keeping your warm air inside the house. Lined draperies and blackout panels increase your insulation as well, maintaining the temperature you want in each room.
Shutters are also very good insulators because they are the thickest, tightest fitting window coverings. They successfully prevent the transmission of air between the window covering and the glass of the window, which reduces energy costs.
