What is the R-value of window shades?
Typical horizontal blinds have an average R-value of 2.5 while honeycomb shades are better insulators and have an R-value between 3.25 to 5.0. By increasing the R-value of your window coverings you can decrease your energy bills.
Do curtains add R-value?
Adding a fabric layer between the curtain and the lining makes a super high-performance insulation system for windows. Research has shown that having well-fitted layered curtains results in an R-value equal to or greater than double-glazing, yet at a fraction of the cost.
Do insulating shades work?
Insulated cellular shades are typically considered to have the highest R-values of all window coverings. In heating seasons, tightly installed cellular shades can reduce heat loss through windows by 40% or more, which equates to about 10% heating energy savings.
Do light filtering shades provide insulation?
Believe it or not, your blinds do have an insulating effect on your home. You probably don’t think of that when buying them, but they do have energy-saving benefits because of their insulating property. According to Alliant Energy, cellular shades can reduce up to 62% of the heat that transfers through a window.
How much insulation do cellular shades provide?
The benefits are significant. 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. In comparison, a typical double pane window has an R-value of 1.8.
What is the R-value of wood blinds?
Comparing R-values & Energy Efficiency Of Window Treatments
| Type of Window Covering | Typical R-Value |
|---|---|
| Blinds | 1.5-2 |
| Pleated shades | 2.5 |
| Drapes | 2-3 |
| Wood Shutters | 3-4 |
What are the most insulating blinds?
Cellular Shades. Cellular shades, or honeycomb shades, are one of the most energy efficient window coverings you can buy. They use a series of honeycomb-like cell pockets to trap air around your windows, keeping your rooms warm in the winter and cool in the summer.
What is the R-value of plantation shutters?
Comparing R-values & Energy Efficiency Of Window Treatments
| Type of Window Covering | Typical R-Value |
|---|---|
| Drapes | 2-3 |
| Wood Shutters | 3-4 |
| Honeycomb shades | 4.5 |
| Polywood plantation shutters | >6 |
What is the R-value of double pane windows?
about 2
R-value measures resistance to heat gain or loss. A typical insulated wall has an R-value anywhere from 12 to 19, while a double-pane window has an R-value of about 2.
Are blackout curtains the same as thermal?
What is the difference between thermal curtains and blackout curtains? Blackout curtains typically feature tightly woven fabric to block out unwanted sunlight. While both blackout and thermal curtains have insulating and blackout qualities, the primary function of thermal curtains is to insulate the room.
What is the R-value of a double pane window?
How does R value affect insulation?
Selecting a shade with higher R-value results in keeping the room cold when the sun is burning outside. A shade of higher R-value helps in reducing the energy bills. Higher the R-value, higher the resistance to heat flow through the window. What is meant by insulation?
What is the R value of a window shade?
The shades double the efficiency of the R-3.5 windows and reduce heat loss through them by 50%. A standard Aluminum blind in a double glazed window carries an R-value of 2.32. A single cellular shade on that same window creates an R-value between 3.5 and 4.3.
What is the R-value of window treatments?
R-value of window treatments. All window treatments are not created equally considering R-values and energy savings. Typical Horizontal blinds have an average R-value of 2.5 while honeycomb shades are better insulators and have an R-value of 3.25 to 5.
What is the R-value of an insulator?
“R-Value” measures the resistance of a particular material to heat flowing through it. The higher the R-value of any given insulator, the greater its heat resistance.
