{friday finds: beat the heat with hunter douglas’ duette architella}

A couple of years ago my neighbor across the street had to take down the huge maple tree in their front yard. Why am I telling you this? I no longer have the canopy of my neighbor’s tree to filter the sun, and shade my home from the afternoon sun. Before the tree went down my house stayed relatively cool; that’s not the case these days.

On my list of things to do (this past spring) was to order Hunter Douglas’ Duette® Architella® Honeycomb Shades for my four west-facing windows. I didn’t do it and I’m already singing the blues in anticipation of my electric bill. What’s so special about the Duette® Architella® Honeycomb Shade?

“Uncovered windows can literally be energy holes, depleting a home of up to half of its heating and cooling energy dollars. We specifically designed and developed the award-winning, design-forward Duette® Architella® shade – our most energy-efficient product and the fastest-growing innovation…to address this problem. This takes the air-trapping cellular structure of our original Duette honeycomb shade and makes it even more energy-efficient by placing a cell within a cell.”  Marv Hopkins, Hunter Douglas President and CEO

 The  Duette® Architella® Honeycomb Shade keeps your house cooler in the summer and here is an explanation as how that is measured. Stay with me, the reduction in heat gain is pretty impressive.

Summer Comfort: Solar Heat Gain Coefficient

A product’s “solar heat gain coefficient” (SHGC) is a measurement of its ability to reduce heat gain from the sun. When used with windows, it is the fraction of solar energy striking a window that actually passes through it to heat the room. SHGC is expressed as a number between 0 (none) and 1 (all). The lower a window’s solar heat gain coefficient, the less solar energy it transmits (i.e., lower is better).

The SHGC of a standard double-glazed window is 0.76, meaning 76% of the incident solar energy is transmitted through it. If we add the same Duette® Architella® shade from the R-value example, the solar heat gain coefficient drops to 0.15 — only 15% of the incident solar energy enters the room to heat it. This greatly reduces the cooling load, saving energy and money. For information on how the Duette® Architella® doubles your insulating R-value in the winter, click here.


The Duette®Architella® will save you money on cooling and heating your home and cut down on your energy consumption. It’s a good thing.
