Insulating Cellular Shades

Posted on: October 23, 2012


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
