The Inside Scoop at CellularWindowShades.com

Posts Tagged ‘window quilts

The past few days the phones have been ringing off the hook with ONE THOUGHT in mind:

“Tell me more about the insulating value of Cellular Window Shades”.

Blinds are certainly a value where there is nothing covering your windows and skylights  <– what one customer called the “black hole” effect. But how does Cellular, specifically, measure up against other window types, mini blinds or window quilts, for instance.

Let’s start with proven savings on cooling AND heating costs:

Upwards of 25% of your costs can be lost through indoor air leaking back outside through your windows and skylights. If you pay $1300, you could be wasting up to $325 annually in heating/cooling! Dare I say it: That amount could buy you THREE 36-inch x 60-inch (width x height) Cellular Shades and still put change in your pocket — thanks to FREE shipping.

By providing window and skylight glass with a Cellular Shade covering, Energy Smart Cellular Shades control drafts – you feel the continuity in temperature. You hear the heating and cooling systems turn on less often.

Symphony Shades, Light Filtering or Black Out fabrics, insulate in 3 ways, as they fight:

  • convection
  • conduction
  • radiation

See our R-Value chart at the end of this post. But first, to answer the question of how Energy Efficient Cellular Shades stack up against other window treatments, check out the insulation “rating” of these popular window coverings, in conjunction with a Double Pane Window:

  • 1-inch mini blinds have an R-Value of 2.3
  • Vertical blinds have an R-Value of 2.3
  • CrystalPleat™ Facets, an R-Value of 3.3
  • Applause™ or Duette™ Classic, an R-Value of 3.5
  • Window Quilts, an R-Value of 3.6

(R-Value measures the thermal resistance –> the HIGHER the number, the more effective the insulating)

NOW compare these insulating values with the R-Values for the various Cellular Window Shades fabrics, without and with ComforTrack sidetracks:

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
Note: Single Cell shades are not available with side tracks

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!
