Summer heat loads can drive indoor temps up by 10 °F or more—but the right window coverings stop that heat before it ever crosses the glass. Insulated cellular shades, performance solar shades, expertly fitted shutters, and Designer Custom Drapery outfitted with thermal or blackout liners are the four proven categories that slash solar gain, protect furnishings, and lighten the load on your A/C.
Everything Blindsgalore sells is cut‑to‑order, so you get factory‑tight fits and optional cordless or motorized lift systems that make daily operation effortless and child‑safe.
Why Summer Heat Is So Tough on Your Home
Windows are the main way heat sneaks into your home. According to the U.S. Department of Energy, around 76% of sunlight that falls on standard double-pane windows enters as heat. That’s why your air conditioner works harder, your furniture fades, and your comfort drops. The right thermal window coverings for summer can block, reflect, or absorb this heat, making your home cooler and your energy bills lower.
What Makes a Window Treatment Summer-Ready?
When you’re looking at window shades online, here’s what we recommend you focus on:
- Insulation: Choose designs that trap air and slow down heat, like insulated cellular shades.
- Solar Reflection: Look for fabrics or finishes that bounce sunlight away, such as solar shades.
- UV Protection: Materials that block harmful rays and prevent fading.
- Easy Operation: Cordless or motorized systems make daily use simple and safe.
- Style: Pick modern designs that fit your space and personal taste.
How Window Treatments Block Heat
Heat gets into your home in three ways: radiation, conduction, and convection. Energy efficient window coverings act as a barrier, stopping heat before it enters or trapping a layer of air to slow it down. The best options combine insulation with solar reflection for maximum comfort and energy savings.
Comparing the Most Effective Window Treatments for Summer
Insulated Cellular Shades (Honeycomb Shades)
Why we love them:
Insulated cellular shades are our top pick for both summer and winter. The honeycomb structure traps air, creating a barrier that keeps hot air out and cool air in. Tightly fitted cellular shades can reduce unwanted solar heat by up to 60% in summer and cut heat loss by 40% in winter. They’re also great for privacy and light control.
Key benefits:
- Superior insulation for year-round comfort
- Blocks up to 99% of incoming light with blackout options

Plantation Shutters and Faux Wood Shutters
Why we love them:
Shutters are classic, durable, and highly effective at blocking heat. When closed, they create a still air pocket between the shutter and window, making them one of the most energy efficient window coverings for both summer and winter.

Blackout Curtains and Thermal Drapes
Drapery can be more than décor; with the correct liner it becomes a soft, elegant insulation blanket. Blindsgalore Designer Custom Drapery lets you choose the exact performance level during checkout—Standard, Room‑Darkening, Thermal, or Premium Blackout (Step 6 in the configurator). Add a thermal or blackout liner and floor‑length panels can cut summer heat gain by up to 33 percent while blocking evening light bleed. Pair them with a sleek cornice or ceiling‑mount track to seal the top gap and maximize efficiency.
Product spotlight: Designer Custom Drapery – Grommet—select your fabric, pick a liner, and create a tailored barrier against both heat and glare.
Key benefits:
- Great for bedrooms and living rooms
- Wide variety of colors and patterns
- Easy to layer with other window treatments
Tip:
Install a cornice or pelmet at the top to prevent heat from escaping over the curtain. Overlap panels in the middle for a tighter seal.
Roller and Roman Shades
Why we love them:
Roller and Roman shades made from light-colored or reflective fabrics can help keep rooms cool. While not as insulating as cellular shades, they’re easy to use and can be layered with other treatments for extra heat protection.
Key benefits:
- Simple, clean look
- Easy to operate
- Wide range of fabrics and colors
Solar Screens
Why we love them:
Solar screens can be applied directly to glass to bounce sunlight away. They’re a cheap way to block heat from windows and are especially useful for renters or hard-to-fit windows.
Key benefits:
- Affordable and easy to install
- Maintains natural light
- Reduces glare and UV exposure
