The best blackout curtains for a bedroom that faces direct morning or afternoon sun, ranked by light-blocking percentage, backing material, and heat insulation for rooms that run noticeably warmer in daylight.
Our Top Picks
Eclipse Palisade Blackout Curtain Panel
Eclipse
- ✓52 x 84 inch single panel, grommet top
- ✓Thermaback triple-weave blackout backing
- ✓Blocks 98% to 99.9% of light
- ✓Reduces energy loss through the window
- ✓Machine washable
Pros
- Thermaback backing is the most effective light and heat blocker tested in this list
- Noticeably reduces afternoon heat buildup in a west-facing room
- Available in dark colorways that maximize both light and heat blocking
Cons
- Sold per panel, so a full pair costs roughly double the single-panel price
- Stiffer fabric hand-feel than a fabric-only curtain
Best for a room with unobstructed direct sun. The Palisade blocks both light and radiant heat more completely than the other panels here.
Lush Decor Insulated Grommet Blackout Curtain Panel Pair
Lush Decor

- ✓Machine washable
Pros
- Sold as a pair, useful for a wide bright window that needs full-width coverage
- Built-in insulation layer helps with afternoon heat buildup
- Darker colorways approach the blocking rate of a laminated panel
Cons
- Lighter colors block noticeably less than the darker options
- Not quite as effective as a laminated Thermaback backing for peak-sun rooms
Best value pair for a wide window facing direct sun, especially in a dark colorway.
Sun Zero Easton Blackout Grommet Curtain Panel

- ✓Blocks up to 90% of light
- ✓Lab-tested to reduce outside noise by 25%

- Affordable enough to double up panels for fuller coverage
- Highest ratings volume of any panel in this list
Cons
- 90% blocking is the lowest rate in this list, noticeable in a room with strong direct sun
- Best suited to moderate rather than intense all-day direct sun
Best budget pick for a bedroom with moderate rather than intense direct sun exposure.
Exclusive Home Curtains Gates Sateen Blackout Curtain Panel Pair
Exclusive Home Curtains
- ✓52 x 63 inch pair, 2 panels
- ✓Sateen twill weave with Light Block and Thermax lining
- ✓Blocks light and blocks harmful UV rays
- ✓8 matte silver grommets per panel
- ✓Machine washable
Pros
- Thermax lining adds a genuine layer of thermal insulation against radiant heat
- Sateen finish looks more polished than a matte utilitarian panel
- UV-blocking claim is a specific, testable feature rather than marketing language
Cons
- 63-inch length is short for floor-length coverage on standard ceiling heights
- Blocks slightly less light than a laminated Thermaback panel in direct comparison
Best insulated sateen option for a bright room that also wants a more finished look.
A bedroom that faces direct morning or afternoon sun turns "blackout curtain" from a nice-to-have into a real test of the fabric.
In this kind of room, the backing material does most of the work. The Eclipse Palisade's Thermaback triple-weave backing blocked the most light and the most heat of anything tested here, at 98% to 99.9% light blocking in a 52 by 84 inch single panel.
The Lush Decor Insulated Grommet pair comes close in a dark colorway and has the advantage of shipping as two panels for full window-width coverage in one order.
Budget shoppers facing moderate rather than intense sun exposure do well with the Sun Zero Easton, which adds a UPF 50+ UV rating on top of its 90% light blocking, useful for protecting furniture and flooring from fading as much as for darkening the room.
The Best Blackout Curtains for Bright Bedrooms at a Glance

Best pair for a wide window: Lush Decor Insulated Grommet, sold as two panels with a built-in insulation layer.
Best budget: Sun Zero Easton, adds explicit UV protection at the lowest price in this list.
Best insulated sateen: Exclusive Home Gates, Thermax lining in a more polished finish.
Why Backing Material Matters More Here Than Anywhere Else
Laminated backings (Thermaback and similar) block the most light and heat. These use a foam or acrylic layer bonded to the back of the fabric, which is why they consistently test at 98%+ blocking versus 90% to 95% for plain woven fabrics.
Dark colors block more than light colors at the same construction. The difference is usually 3 to 5 percentage points, which matters more in a room with strong direct sun than in a room with indirect or filtered light.
A second layer helps in extreme cases. For a room with unobstructed all-day direct sun, pairing a blackout curtain with a cellular shade or blackout liner closes the last few percentage points that even the best single panel leaves open.
