Your windows are essential for letting the sunshine in, but they can also let in chilly drafts—or send your home’s heat on a one-way trip out. Still, we take the good with the bad because otherwise, we couldn’t keep indoor plants happy, let in the breeze, or watch the birds munching cheerfully at their feeder.
Fortunately, with the right window treatments, it doesn’t have to be so much of an expense to your comfort (or your wallet). Here are the best-of-the-best options for blinds and energy-efficient window treatments.
1. Cellular Shades

Cellular shades can’t be beat when it comes to insulating the interior of your home. These have a raised and folded texture in the shape of a honeycomb. The shapes create a series of air pockets that hold heat from your HVAC system in, while also significantly reducing unwanted solar heat to keep your space cool.
For maximum energy savings, go for cellular shades that operate on side tracks, ensuring complete and consistent coverage. However, if you’re more interested in controlling the amount of sunlight your shades let in, choose a variety that opens from both the top and bottom.
Pros | Cons |
---|---|
Excellent insulation | Difficult to clean |
Privacy | Not much adjustability |
Blocks out noise | Not very fashionable |
Best For: Homeowners looking to save money on energy
2. Thermal Roman Shades

Roman shades are fabric window shades that are folded accordion-style. A tug at a string moves them up or down. These aren’t as effective as other shades at climate control—look for heavier thermal fabrics for the most insulation.
Pros | Cons |
---|---|
Very customizable | Not very long-lasting |
Easy to install | Can easily stain |
Affordable | Not resistant to wear and tear |
Best For: Homeowners looking primarily for room darkening and privacy
3. Exterior Shades

If your home gets oodles of hot sunlight during the day, consider exterior shades for your deck, porch, or patio. These won’t help hold heat in, but these shades can keep heat out of your home. As a bonus, they allow you to enjoy your outdoor space without being blinded by the light.
Pros | Cons |
---|---|
Very durable | Expensive |
Can easily be cleaned | Difficult to install |
Prevents more heat from entering home | Require a lot of maintenance |
Best For: Homeowners looking to reduce as much solar heat as possible
4. Louvered Blinds

Louvered blinds are one of the best types of blinds to keep heat out and blindingly bright sunshine. These are either vertical (called Venetian blinds) or horizontal slats (louvered) and are fantastic for controlling the amount of sun that enters your home. The downside is that, due to the many openings between the slats, they aren’t the best at preventing heat loss during the winter. You may want to hire a local blind installer, as they can be difficult to DIY.
Pros | Cons |
---|---|
Good for light control | Not great at preventing heat loss |
Affordable | Difficult to install |
Offer good privacy | Require extra maintenance |
Best For: Reducing glare and providing flexibility
5. Shutters

Shutters have timeless beauty and elegance, with ample climate-control capabilities to boot. They’re a great solution for making older windows more energy-efficient, but they’re also a fantastic choice all around. Their solid, rigid material closes tightly for fewer gaps, keeping your heat in or blocking out sweltering UV rays as needed. Did we mention how beautiful they are, too?
Pros | Cons |
---|---|
Energy-efficient | Expensive |
Good temperature control | Don’t work on all windows |
Stylish | Can’t hide them |
Best For: Reducing solar heat gain and adjusting how much daylight enters
6. Window Quilts
As the name suggests, a window quilt is essentially a cozy quilt for your windows. The quilted material is rolled and unrolled to open and close, typically on tracks or held with velcro, snaps, or other fasteners. These snuggle up close to your window trim, making them especially effective when the nights get nippy. Pair them with your own comfy quilt, and you’ll be snug as a bug.
Pros | Cons |
---|---|
Effective at keeping in heat | Difficult to install |
Noise reduction | Require a lot of maintenance |
Good light control | Stain easily |
Best For: Affordability and efficiently conducting heat
7. Curtains/Drapes

Curtains and drapes are classic window treatment options, with endless colors and varieties to accent your home decor. Note that these come in a huge array of fabrics and styles, so be sure to pick varieties specifically designed for insulation and climate control.
Pros | Cons |
---|---|
Very customizable | Difficult to install |
Energy-efficient | Hard to clean |
Privacy | Can accumulate dust |
Best For: Aesthetics and blocking sunlight
8. Window Films

Window films are applied directly to a window’s surface, making them ideal for those who don’t want to obscure their outdoor views. They’re also a great option for odd-shaped windows that are difficult to fit with other treatments. These are most effective at blocking out solar heat as well as UV damage to upholstery and artwork.
Pros | Cons |
---|---|
Good at blocking sun | Difficult to install |
Save money on energy bills | Quality varies drastically by brand |
Added security | Loss of heat |
