Proof Positive: Insulated Window Blinds Work


Most companies selling blinds, shades and shutters claim that their window treatments are insulated window blinds. But that simply isn’t true. Anything that doesn’t put a complete seal around a window will not be totally effective at stopping the sun’s radiation and winter’s chill from penetrating single, double and even triple pane windows.

With that said anything covering windows is a step in the right direction, but our Insulated Window Blinds are far superior for the reasons that we will detail below.  No other blind, shade or shutter can offer an R-value of 6 or 13, which is guaranteed with our Insulated Window Blinds.

The cool thing about our Insulated Windows Blinds is that they look like the real thing, but can be purchased for a fraction of the price that most people pay to install energy efficient window treatments and/or triple pane windows.

First let’s take a look at a thermal image of a home’s windows to see how much energy is being lost.

Summertime Savings: Insulated Window Blinds


The following pictures show the inside and outside temperatures with our Insulated Window Blinds installed.  It is important to note that these window temperatures are taken without the AC or heater running on the inside of the test home.

Note that during the summer there is an average temperature difference of ~20 degrees, which may not sound like much, but if you have 20 windows that measure 3′ x ‘5 or 15 sq. ft. each that equals 300 sq. ft of window space that is 20 degrees cooler with Insulated Window Blinds installed.

It doesn’t take a rocket scientist to do the math and calculate that it will be much easier on a home’s AC unit to cool windows at 81 degrees versus 104 degrees.

Wintertime Savings: Insulated Window Blinds


Insulated Windows blinds are great at blocking the sun’s heat from penetrating windows, but they are even more effective at keeping heat from leaking out of windows during cold winter days.

As you can see from these pictures, the inside temperature of windows is 55 degrees without the heater running at all, while the outside temperature of the windows is 28 degrees. That is a difference of 27 degrees and that is with a 1″ piece of insulation with an R-value of 6.  A 2″ Insulated Window Blind will double the R-value to a factor of 13.  We don’t have any test homes in the northeast, but we are confident that the energy savings are worth looking into by all homeowners, especially if you live in very cold wintertime environment.

In Austin, it rarely gets below freezing for more than a couple of days. But in places like Illinois, Michigan, Pennsylvania, Idaho, Wyoming, N/S Dakota, etc., our Insulated Window Blinds can make a huge difference in a home’s, apartment’s or business’ energy bills.

In these pictures you can see that we have white mini-blinds on the outside and wooden blinds on the inside during the summer because white reflects the most heat from the sun.

In the wintertime, we flip the Insulated Window Blinds so that the darker blinds are on the outside. This heats up the window and helps prevent and/or reduce window condensation during cold wintertime months. For really cold places we can make the wood color darker to improve the heating capabilities.
