Insulating Cellular Shades Provide Savings on Heating and Cooling Costs

Did you know that 10-25% of your heating costs are wasted when heat leaks out of your windows?

On average, it costs about $1,300 to heat an American home each year. If you do the math, that’s up to $325 going out your window! Energy saving Symphony cellular shades control drafts to keep temperatures at a constant, so air conditioners and heaters aren't working so hard to keep the room regulated.

What is R-Value? Understanding the Terminology

You may have heard of it before, but haven’t understood what exactly it stands for. The R-Value is a measure of how well a material’s resistance is to heat flow and how well it resists heat gain or loss. Let’s make it simple, the higher the R-Value your material has, the better insulation that you will receive.

R-Value and Your Windows

Your windows themselves have an R-value. A typical window has an R-value ranging from 0.9 to 3.0. To put this in perspective, the insulation that is used to build a home today has an R-value in the low 40s. Essentially, your window is a hole in the wall!

Take a look at this chart explaining how the R-Value of a given cellular shade corresponds to the type of window being covered.

Energy Loss Through Thermal Images

Browse the images below to see thermal loss. This particular scenario is during a cold night with room temperature around 68 degrees F.

These three images were taken in Vermont with a FLIR IR camera by the team at CellularWindowShades.com. You can see clearly that the glass temperature went from 28 degrees at 8pm with no shade to 61.5 degrees with the shades down but no side tracks (9:13 pm) to 64 degrees with the shade down and with side tracks in place (9:16 pm). All of the shades in this these photos were taken using our double cell black out shades.

When the shade is down, it is sitting on the sill so it is interrupting the convection current which reduces heat loss. This kind of temperature gradient affects radiant and conductive heat loss. This amazing temperature difference will make the room more comfortable and will help save you on your energy bill because you will not be driven to raise the thermostat.

Symphony Cellular Shades Help Insulate in 3 Ways:

  1. Fight Convection: Seals gaps that may exist between the window and window frame, blocking the natural airflow and keeping warmer air inside during winter and outside during summer.
  2. Fight Conduction: Energy Smart Cellular Shades create an effective barrier between the glass window and your room, preventing heat transfer with the non-woven polyester fabric and double-honeycomb cell structure.
  3. Fight Radiation: Symphony light filtering and black out cellular shades trap heat between the window and the closed shade, making your home comfortable and warm.

Add the ComforTrack Plus Sidetrack System

Want to save even more on your monthly energy bill? Browse our energy saving sidetracks which seal around your window.

Sidetracks close the gap between the shade and the window frame, preventing even more energy loss! 

These sidetracks will help you save an additional 20% on both your heating and cooling costs than shades without tracks. ComforTrack Plus Sidetracks have been evaluated and verified by the Consortium for Advanced Residential Buildings (CARB).
