With the weather turning colder — even traditionally warm areas of the U.S. have experienced cooler weather lately, thoughts have been turning to windows.

How much cooler-air leaks through your windows can be the difference between comfort and turning up the heat. Or, as I was reminded yesterday by a co-worker: turning ON the heat.

Here’s a truly lovely room:

I can image curling up in one of these chairs, with the throw over the knees, that good book in hand. What happens, though, when the sun stops shining, the cool night descends and you still want to keep on reading?? Pull down your shades and you may even be able to throw off that throw!

So, how about those R-Values?

I copy some information that is found in fuller form on our website: PROVEN SAVINGS ON COOLING AND HEATING COSTS

Whenever I speak with customers, I give the R-values for “shade alone”. Everyone seems to know R-values of their windows; to that number add these R-values for the Double cell fabric:

  • Double Cell Light Filtering fabric – 2.8 R-value
  • Double Cell Black Out fabric – 4.0 R-value

Or, add these values for the Single cell fabric:

  • Single Cell Light Filtering fabric – 1.6 R-value
  • Single Cell Black Out fabric – 2.5 R-value

And how do Cellular Window Shades compare to other window treatments? We’ve got information on that too:

Looking at just R-values (our online comparison charts Energy Efficiency of Cellular Shades versus Other Window Treatments encompasses also cleanability, ease of operation, and overall product ratings),

  • 1-inch Mini blinds or Vertical Blinds – 2.3 R-value
  • Pleated Shades – 2.5 R-value
  • “Crystalpleat” Facets – 3.3 R-value
  • Applause or Duette Classic – 3.5 R-value

It might interest you, with the entry of two Hunter Douglas products (the Applause and Duette), to read this recent one-page article in This Old House magazine.

What about the ubiquitous Window Quilt? How does the Cellular Window Shade stack up? We’ve some GREAT information on all aspects of the Window Quilt versus the Cellular Shade so do read the website for further information, here I’ll just comment on the R-value:

Data includes the window this time, so the bulky Window Quilt is projected to have an R-value of 7.14 depending on the window. The comparable test with the Cellular Window Shade found the R-value to be nearly neck-and-near: R-value of 6.8, likewise depending on window glazing.

If you want to better ever those values, check out literature on the Energy-Savings Side Tracks, the ComforTrack-Plus system!

With Side Tracks, you gain more light-blocking AND also these greater R-values:

  • Double Cell Light Filtering fabric – 2.8 R-value —> 3.3 R-value + your window’s R-value
  • Double Cell Black Out fabric – 4.0 R-value —> 4.7 R-value + your window’s R-value

Now THAT is “Value” and true “bang for your buck”.

And, for the 2011 Tax Year: These shades qualify for Federal Energy Tax Credit!

Thursday, I spoke to a woman who had installed the ComforTracks side-tracks, but was unable to pull the shade down over the crank.

She was adamant that the depth required for the side tracks — a minimum of 1 1/2 inches, but a flush mount requires 1 7/8 inches — was available on her window, yet was curious that the shade could not be pulled completely down, because of the crank handle.

Take a look at this window – its flat surface depth – its crank.

If we assume the flat surface depth is 2-inches, one can concede that tracks could be applied to this window. But look closely at the handle: it is the full depth of that flat surface! So for this window to fully accommodate a cellular window shade with side tracks, it would require the depth of 1 1/2 to 2-inches as measured from the furthest point beyond that handle.

The greatest hint I can give about measuring is NOT to measure depth with the idea of where is the point of greatest depth (for even sash windows have more depth on the upper sash than the lower sash), but where is the point of least-greatest depth.

This user could have side tracks on their window – but the shade will never clear that crank at the bottom. If the molding were straight out for another couple inches, the story would be quite different. Always remember: it is flat surface depth beyond any window obstructions like cranks, handles and locks.

For more information, see our measuring guide.

I am reminded to say that long-handled CRANKS are a thing of the past: check out our supply of T-Handles. NOTE: This will help your profile, but not solve all lack-of-depth problems.
