Insulated cellular shades are typically considered to have the highest R-values of all window coverings. The air pockets in the honeycomb cross-sections act as insulators, increasing the R-value and reducing the conduction of heat through the window.
The most energy efficient windows are triple-pane windows, known for their superior insulation. These windows are followed by double pane and then single pane options in terms of efficiency.
Cellular Shades
honeycomb-like cell pockets to trap air around your windows, keeping your rooms warm in the winter and cool in the summer. They're one of the best window coverings to keep heat out and to keep cold out. Cellular shades come in a wide range of colors.
Blinds Versus Curtains
In general, curtains are better for retaining heat in the home. However, by choosing a thermal blind you can reduce heat loss from your home by 20-40%, while thermal curtains reduce heat loss by just 25%-30%.
Double-Pane and Triple-Pane Windows
Today's triple-pane or double-pane windows are the most highly recommended for maximum energy efficiency in virtually all climate zones. The insular space between the window panes saves energy and helps reduce electricity costs.

One of the best heat reducing window film options on the market today, the 3M Residential Ceramic Sun Control Window Film will reject up to 80% of harmful heat-producing infrared rays.
Because blinds require slats to function, heat can easily escape through the slats. Whereas, curtains don't require slats so heat is easily maintained. The thicker the curtain is the more insulated they are. However, in summer, blinds are better than curtains for energy efficiency.
For the best heat-blocking ability, opt for tightly woven, medium-to-heavyweight cotton drapery.
Zebra blinds are energy efficient and help keep the temperature outside from coming through your windows. Simply installing these window treatments could save you an average of 30%. During the summer months they keep the heat from warming up your space, while in winter they keep the cold from entering.
Energy Efficiency
Plantation shutters are energy-efficient because they are installed in such a way that they seal right up against the window frame. This helps to prevent inside air from escaping to the outside and prevents outside air from entering your home.
Exterior doors that meet applicable Energy Star requirements. Credit is limited to $250 per door and $500 total. Exterior windows and skylights that meet Energy Star Most Efficient certification requirements. Credit is limited to $600 total.
Windows with high R values include double-glazed windows, triple-glazed windows, and argon-filled windows. Double-glazed windows have two layers of glass with a space in between, while triple-glazed windows have three layers of glass.
Triple-pane glass has an additional air space and third sheet of glass added, which makes this the most-efficient glass type. Andersen® windows come standard with dual-pane glass, and triple-pane glass is an option on A-Series and E-Series windows.
Another benefit of blackout drapery is their ability to reduce your energy costs. In most homes, 10-25% of thermal energy loss is from windows. However, with blackout drapes, your energy bill could be reduced up to 25%. During the winter, blackout drapery will help keep the heat in the room.
Thick curtains are one of the main ways to protect your house from losing heat through the windows. Curtains with a thermal lining are a relatively cheap option, says Brennand. "The thicker the better," adds Archna Luthra, consumer analyst at moneysavingexpert.com.
Drapery will typically cost more than blinds to cover the exact same area, due to the sheer amount of material they often require. Plus, drapery also requires more components for installation, including not only the curtain panels, but also the hardware such as rod and rings or track system, brackets, etc.
Increase the Shade
Adding window treatments is one of the easiest ways to keep sunlight from heating your living space. Curtains or drapes with a reflective or light-colored backing would do the best job since they won't absorb extra heat. In addition, you can consider getting adjustable blinds or a roller-type shade.
Aluminium foil is both pliable, cheap and highly resistant to high temperatures. Spreading tin foil on any windows that receive direct sunlight can redirect the sun and heat away from your home.
