Cellular Window Shade

For your room’s window!

Cellular Window Shades are perfect for retaining your home’s heat: Today I was talking to a man who had just taken delivery of his recent shade order. He was so enthusiastic! And tonight will be the FIRST time a room (kept at 60-degrees this winter) will have SHADES in the windows at all.

“You will find it makes a WORLD of difference,” I told him, “regarding your comfort as well as the energy savings” — and that’s no mere boast. I sit directly below a “leaky” double-paned window. Today, especially, the only thing that kept me warm was the cellular window shade: I didn’t lift it up till 2 pm! (Winter sun = must “bask” in it)

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

The Green Building Forum, in the UK, featured this recent Q&A session about blinds. One forum-poster, JT, confessed “I think I’ve been so fixated on heat loss that I hadn’t given thought to avoiding overheating.”

With July temperatures already wilting many communities, OVERheating — through glass found in windows, patio doors, and skylights — is a concern.

Of exceptional interest is James’s link to this article on Thermal Performance of Traditional Windows. I have “original” windows in my modest Cape-style home here in Vermont, and have blogged a couple of times about the value and also the historic desirability of original sash windows (never mind the landfill conundrum). This article actually uses the phrase “evidence is available to counteract some of the misconceptions about the energy efficiency of original timber sash windows“. They advocate simple repairs and “basic improvements”.

In point number 3, where there is discussion of curtains and “roller blinds”, imagine how much more effective and efficient those windows could be with Cellular window shades. We’ve got data to back up our assertions: Check out our R-values for Cellular Shades page.

If the UK strives to target U-value for windows of 2 or below then more windows should be covered by Cellular Shades: “To compare R-value and U-factor, divide 1 by the U-factor number,” says the site Efficient Windows.org. Using this to get an R-value for “high performance double-pane windows” -> with a U-factor of 0.30 on average – that equates an R-value of 3.33.

This R-value is desirable: and what comes close is the Light Filtering Cellular Window shade fabric, with an R-value of 2.8.

Add side tracks to that same shade and you’ve raised the R-value to 3.3 — and tied that “high performance double-pane” window.

Use Black Out fabric rather than Light Filtering fabric and you up those values even more: R-value of 4.0 and, if you add side tracks, 4.7.

These numbers are for SHADE ALONE. Once you factor in the window itself, you’re potentially reaching R-values in the range of 8.2.

So how does all this help with keeping OUT the hot weather, as well as keeping in HEAT during the winter months?

English Heritage has produced a video Sash Windows – Why They Are Worth Keeping. The same link also gives access to a couple of well-thought-out publications on improving thermal performance.

It’s a two-way street: What improves to keep heating inside rather than dissipating to the outdoors also helps keep the sweltering outdoor temperatures from impacting your internal temperature. If outdoor heat doesn’t enter your premises, then your cooling system — whether a/c units or fans — can relax and work much less.

If you answer the following question, with a YES, maybe it’s time
to research Cellular Shades and Skylights:

Do you start your air conditioning early in the morning,
and run it all day??

Australians are not quite “baking in summer heat” —

But look at those humidity levels! You know that it’s just a matter of time before the heat again builds to record levels.

So why am I talking intense heat in a season when the northern United States braces for COLD weather?? The simple fact is, Cellular Window Shades do duty in ALL seasons! Their insulating capabilities help keep out winter’s cold as well as summer’s heat.

While everyone on the glob is preparing for the end-of-year festivities, some forward-thinking people are thinking about their personal comfort. And that’s really what being neither too-cold nor too-hot is all about. Personal comfort and saving energy. There’s nothing like “giving back” to help generate some well-deserved “holiday cheer”.

Cellular Shades give back in several ways:

  1. by reducing your heating and cooling costs
  2. by helping to provide a temperature-stable environment
  3. by lending your home color and beautifying your decor
  4. as well, they are a durable, US-made product.
