NICETOWN Room Darkening Curtains Review: Do They Really Block 99% of Light?

Overview

The Blackout Curtains That Actually Block Out Light

If you’ve ever bought “blackout” curtains that still let in a soft glow at 6am, you know the disappointment. NICETOWN’s Room Darkening Blackout Curtains use a triple-weave fabric construction to block 85%–99% of light and UV rays, turning any bedroom into a proper cave for sleeping in — no matter what time the sun comes up.

Beyond just blocking light, the thermal-insulated fabric helps regulate room temperature season to season, cuts down on outside noise, and protects furniture and flooring from sun damage. They’re sold as ready-made grommet-top panels in a huge range of sizes and colors, so there’s a fit for nearly any window in the house.

Light Blocking

Real Darkness, Not “Dim-ish”

These panels block 85%–99% of incoming light and UV rays, with darker colors like black and hunter green landing at the top end of that range. That means no streetlights sneaking through, no early sunrise waking you up, and a noticeably better TV or movie-watching experience during the day.

It’s the kind of difference you don’t fully appreciate until you compare it side by side with a regular curtain — the room genuinely goes dark, not just dimmer.

The Fabric

Triple Weave Technology Explained

Instead of a single layer of fabric, each panel is built from a front layer, a middle black yarn layer, and a back layer woven together. That extra middle layer is what does the heavy lifting for light blocking, noise reduction, and insulation, without making the fabric feel stiff or paper-thin.

The result is a curtain that feels soft and substantial in the hand, hangs with a nice natural drape, and still does the job of a much heavier blackout liner.

Energy Smart

Keeps Rooms Cooler in Summer, Warmer in Winter

The insulating fabric helps buffer your room against outside temperature swings, blocking summer heat and holding in winter warmth. Over time that can take some pressure off your HVAC system, and the curtains pay for themselves the longer you use them.

They also help protect furniture, flooring, and artwork from sun fading, which is an easy thing to overlook until you notice a sun-bleached patch on your rug.

The Hardware

Silver Grommets That Glide Smoothly

Each panel comes with 6 rust-resistant silver grommets with a 1.6-inch inner diameter, sized to fit standard curtain rods without any extra hardware to buy. The rings let the curtains slide open and closed smoothly instead of sticking or bunching.

Threads are neatly trimmed and the fabric comes wrinkle-free out of the packaging, so panels are ready to hang the same day they arrive — no ironing required before you put them up.

Sizing

A Size for Nearly Every Window

Panels are available in widths from 29″ to 66″ and lengths from 20″ up to 120″, across five width categories. That range covers everything from small bathroom windows to oversized patio doors.

As a rule of thumb, each panel should measure roughly 1.5 to 2 times the width of your window for a nice full, gathered look when closed — allow for about 1″ of deviation since these are manually measured.

Easy Care

Machine Washable, No Special Care Needed

These curtains are machine washable in cold water and can go straight into the tumble dryer on low, so there’s no dry-cleaning bill to worry about. If a quick touch-up is needed, a low iron or a light steam takes care of it.

Just skip the bleach — the polyester fabric holds up well over time with normal washing, but bleach will damage the color and the coating that helps block light.
