Lots of people call in and ask about what the R-Value is of our shades. R-Value is defined as: “the capacity of an insulating material to resist heat flow. The higher the R-value, the greater the insulating power.”
Our shades have different R-Values depending on the type of shade and how many panes of glass the window has. Sidetracks increase the insulating power as well. Below is a list of our shades and how they compare to each other:
Compare R-Value by Fabric Type | Shade Only | Single Pane (+1) | Double Pane (+1.8) | Triple Pane (+3.5) |
---|---|---|---|---|
Double Cell Light Filtering | 2.8 | 3.8 | 4.6 | 6.3 |
Double Cell Light Filtering With Tracks | 3.3 | 4.3 | 5.1 | 6.8 |
Double Cell Black Out | 4.0 | 5.0 | 5.8 | 7.5 |
Double Cell Black Out With Tracks | 4.7 | 5.7 | 6.5 | 8.2 |
Single Cell Light Filtering | 1.6 | 2.6 | 3.4 | 5.1 |
Single Cell Black Out | 2.5 | 3.5 | 4.3 | 6 |
