Insulate your windows in every season
Windows are where homes lose the most heat in winter and gain the most in summer. The right shade puts a layer of insulation right where you need it — slowing heat transfer through the glass in both directions, which can help take the edge off your heating and cooling.
Who it's best for
- Drafty or west-facing rooms
- Homeowners watching heating and cooling costs
- Large windows and great-rooms with big temperature swings
- Colorado homes facing real winters and hot, high-altitude sun

Your options, in plain terms
Duette® cellular (honeycomb) shades
Duette® honeycomb cells trap air at the glass, slowing heat transfer in both directions. The single most effective insulating shade we sell — and our most-recommended for energy.
Architella® — a cell within a cell
Architella® adds a honeycomb inside the honeycomb, creating extra air pockets for even higher insulation. Worth considering for large or especially drafty windows.
Exterior shades for heat
Stopping the sun outside the glass is the most effective way to keep a room cool. Exterior shades pair well with interior insulation on sun-blasted west and south faces.
Worth thinking through
Design considerations
Start with your worst rooms
West- and south-facing rooms and big banks of glass swing the most in temperature, so they return the most from an insulating shade. They're the place to start if you're prioritizing.
Works in both seasons
The same trapped-air layer that keeps heat in during a Colorado winter keeps it out during summer — so an insulating shade earns its keep year-round, not just in one season.

Good to know
Common questions
Which shade saves the most energy?
Duette® cellular shades, because the honeycomb structure adds an insulating air pocket right at the window — helpful in both Colorado winters and summers. Architella® goes a step further with a cell-within-a-cell design.
How does a honeycomb shade actually insulate?
Its cells trap a layer of still air against the glass. Still air is a poor conductor of heat, so it slows the transfer that would otherwise happen straight through the window — in both directions.
Do exterior shades help in summer?
Yes — and they're the most effective option for heat, because they stop the sun before it ever reaches the glass. On hot west- and south-facing windows they pair well with interior insulating shades.
