Drafty winters. Intense summer sunshine. Colorado homeowners experience both extremes, and your windows may be playing a bigger role than you realize. In fact, significant heat gain and energy loss can happen right at the window. The good news? The right energy efficient window treatments can help improve comfort year-round while still allowing you to enjoy natural light and beautiful views.
From reducing glare and blocking UV rays to improving insulation and controlling indoor temperatures, today’s window coverings do far more than simply cover the glass. Let’s explore some of the best energy efficient window treatments for Denver homes.
How Energy Efficient Window Treatments Work
Large windows and direct sunlight can dramatically affect the atmosphere inside your home. Heat transfer through glass can create uncomfortable hot spots during the summer and chilly drafts during winter.

The right window coverings help by:
- reducing solar heat gain
- slowing heat loss during colder months
- blocking harsh glare
- protecting interiors from UV damage
- improving overall indoor comfort
Some treatments insulate the window itself, while others diffuse sunlight, reduce airflow, or reflect radiant heat away from the room. If you’re trying to solve issues with overheating rooms, glare, or fluctuating temperatures, explore our energy efficient window solutions for additional inspiration.
Honeycomb Shades for Insulation
When homeowners ask about the most energy efficient window treatments, honeycomb shades are often at the top of the list. Also known as cellular shades, their unique construction traps air inside honeycomb-shaped pockets, creating insulation at the window. This helps maintain indoor temperatures throughout the year—keeping your home cooler in summer and warmer in winter.

Duette® Honeycomb Shades are especially popular in Colorado homes because they help reduce drafts, soften incoming light, and improve comfort without sacrificing style. They are also available in vertical applications for large windows and sliding glass doors. For even greater flexibility, features like Duolite® allow homeowners to combine light-filtering and room-darkening fabrics on the same window.
Cellular Roller Shades: Modern Style + Energy Savings
If you love the clean appearance of roller shades but want added insulation, Sonnette™ Cellular Roller Shades combine both benefits beautifully.

These innovative shades feature a curved cellular design that helps reduce heat transfer while maintaining the streamlined look of a roller shade. They’re a favorite for large windows and modern homes where both comfort and simplicity matter.
Roman Shades that Soften Light + Heat
Roman shades bring softness and style while also helping improve comfort at the window. Because layered fabrics naturally slow airflow and diffuse sunlight, roman shades can help reduce heat buildup while creating a warm, inviting atmosphere. Fabric opacity and liner choices allow you to customize how much light and insulation you want in each room.

Features like Top Down Bottom Up shades also give homeowners more flexibility to enjoy daylight while controlling glare and privacy.
Plantation Shutters for Year-Round Comfort
Plantation shutters have long been known for their insulating qualities. Installed directly into the window frame, shutters create an additional barrier between your home and the outdoor elements.

When adjusted properly, shutters can direct natural light upward while reducing direct glare and limiting solar heat gain. Their solid construction also helps reduce airflow around the window.
Sheer Shades That Reduce Glare While Preserving the View
Energy efficiency isn’t always about blocking all the light. Sometimes it’s about managing it more effectively. Sheer shades help soften incoming sunlight, reduce glare, and protect interiors from UV rays while still maintaining beautiful outdoor views.

Reflective sheer fabrics diffuse harsh sunshine and can help reduce radiant heat transfer—especially on large or west-facing windows.
Smart Shades + Automated Energy Efficiency
One of the most overlooked ways to improve energy efficiency is through automation. With PowerView® Automation, shades can automatically adjust throughout the day based on sunlight, time of day, or your personal schedule.
This means you can:
- reduce afternoon heat gain automatically
- maximize daylight without excessive glare
- improve comfort throughout the day
- protect interiors from UV exposure
- control hard-to-reach windows effortlessly

Choosing the Best Energy Efficient Window Treatments
The best solution depends on:
- the direction your windows face
- how much natural light you want
- privacy needs
- window size and placement
- whether heat gain or drafts are the bigger issue
Some homeowners prioritize insulation. Others want glare reduction while preserving mountain views. Many want a combination of comfort, light control, and design. If you’re also dealing with excessive sunlight and overheating, explore our window treatments for large windows solutions page.
