The air pockets in the honeycomb cross-sections act as insulators, increasing the R-value and reducing the conduction of heat through the window. In heating seasons, tightly installed cellular shades can reduce heat loss through windows by 40% or more, which equates to about 20% heating energy savings.
Just so, are honeycomb shades energy efficient?
Cellular shades are the best and most energy efficient window coverings you can buy. They use a series of cell pockets to trap air around your windows, keeping your rooms warm in the winter and cool in the summer. The cells use a unique design shape similar to a honeycomb and are often referred to as honeycomb shades.
Keeping this in consideration, do honeycomb blinds keep heat in?
Honeycomb shades can block heat about as well as a 1/8 inch sheet of insulated foam. Their R-value (or, their ability to insulate against heat flow) ranges between 2 and 5.
Because of their two layers, double cell shades give you better insulation from loud noise. They also insulate you and increase your energy efficiency a little better than single-cell shades do. Typically, shades with a 3/8 inch cell measurement and less work well for smaller windows.
