▣ Green Energy Saving Window Covering Options

As much as 40% of a home’s energy is lost through its windows.  Most people are unaware of this energy loss and the cost savings available by installing energy-efficient window fashions in their homes. Interior Spaces is a priority dealer for  Hunter Douglas and a full service interior design firm in the Portland, OR area.  We are committed to providing environmentally friendly products that not only use sustainable and recycled materials where possible but also reduce energy consumption by better insulating windows.

Glass offers very little resistance to heat flow. Because of this, windows are “energy holes.” Compared to the well-insulated walls and roofs of modern homes, standard double-pane windows allow 10 to 15 times more heat energy to flow through them. So, despite the fact that windows make up only 10 percent of a home’s exterior, approximately 50 percent of the home’s heating and cooling energy pours through them… which means that about half of what is paid for heating and cooling utility bills pours through them, too.

                                    

Slowing the energy flow

The infrared photo above graphically shows the energy loss through windows. Notice the dramatic color difference between the walls and windows, highlighting the contrast in resistance to heat flow. How do we make the windows more like walls? We add insulation. Not with the fiberglass you would find in the walls,

of course, but with window coverings like Hunter Douglas new Duette® Architella® honeycomb shades. The patented honeycomb-within-a-honeycomb construction forms three air pockets for superior insulation between the window and the room.

 

Expected savings

Hunter Douglas new Duette® Architella® honeycomb shades have the highest energy rating that I have found.   It triples the energy efficiency of standard double-pane windows when fully recessed inside the window opening. This significantly decreases heat loss in winter and heat gain in summer, providing substantial energy and cost savings. One of our clients, who in an accountant, recently purchased Duette Architella shades for their lake house. They called to tell me, that in one winter month, it saved them about 25% on their monthly energy bill! Needless to say, he was happy to have such a quick return on his investment. Hunter Douglas is offering incredible rebates back on the Architella® shades this summer, plus with our 25% off summer sale, you will save energy and investment dollars!  Call Interior Spaces at 503-692-6077, full service interior design firm in in Portland Oregon area now to schedule your free in-home consultation.
