1. Introduction
The Moondream DecibelControl 3-in-1 Soundproof Curtain Noise Reduction Thermal Insulation 100% Blackout Patented Technology Made in Europe Grommet Grey Cloud MC09 and the Elfzone Window Insulation for Winter 39 70in Blackout Curtain Soundproof Curtains Oxford Cloth and Cotton Fiber Filled Black Out Shades for Living Room Bedroom Gray both focus on light control and insulation, but they approach “soundproof curtain” design differently. Moondream is presented as a single, ready-to-hang grommet panel with a stated “up to 10 decibels” noise reduction and 100% blackout, while Elfzone is presented as an insulated window cover set that installs with Velcro and a zipper and is described as blocking 99.9% sunlight.
- Blackout claim: Moondream is described as 100% blackout, while Elfzone is described as blocking 99.9% sunlight.
- Sound claim detail: Moondream includes a specific “up to 10 decibels” noise reduction claim; Elfzone describes noise absorption without a decibel figure.
- Install style: Moondream is described as a grommet, ready-to-hang curtain panel for a rod; Elfzone is described as using double-sided Velcro and a zipper closure.
- Materials framing: Moondream is listed as polyester with a three-layer build that includes thick cotton; Elfzone is listed as cotton with thick Oxford fabric and cotton padding/filling.
- Positioning details: Moondream is described as made in Europe with patented technology; Elfzone is described as moisture resistant and wind proof.
If you want a fast way to decide, the comparison usually comes down to whether you prefer a rod-hung curtain panel with a stated decibel claim (Moondream) or a Velcro-installed insulated cover set with zipper closure (Elfzone).
2. Key Decision Factors Identified From the Review Content
The clearest decision points are the blackout level (100% vs 99.9%), how each product is described to handle sound (a stated “up to 10 decibels” reduction vs noise absorption language), the installation method (grommet rod panel vs Velcro + zipper cover set), and the way insulation is described (cold/heat insulation vs reduced cold air leaks and wind proof framing).

- Noise claim specificity
- Installation method and closure type

3. Moondream DecibelControl 3-in-1 Soundproof Curtain Noise Reduction Thermal Insulation 100% Blackout Patented Technology Made in Europe Grommet Grey Cloud MC09 Overview
Moondream DecibelControl is presented as a 3-in-1 curtain intended to combine soundproofing, thermal insulation, and blackout in a single panel. The write-up describes a three-layer construction (blackout fabric, thermal lining, and thick cotton), lists the material as polyester, and frames the panel as an acoustic barrier that can reduce noise by up to 10 decibels while blocking 100% of outside light.
Installation is described as grommet-based and ready-to-hang on a curtain rod, and the panel is listed with dimensions of 95" L x 55" W. The product is also described as manufactured in Europe and using patented technology (U.S. Patent N° 9475260). If you want to check the product listing directly, Moondream is referenced as the relevant listing link.
Buyer feedback in the write-up is presented as frequently noting thickness and light blocking, while noise reduction impressions are described as mixed. For product-page specifics, the listing link for Moondream is included in the write-up, and the same Moondream listing is referenced again where detailed specifications are discussed.
4. Elfzone Window Insulation for Winter 39 70in Blackout Curtain Soundproof Curtains Oxford Cloth and Cotton Fiber Filled Black Out Shades for Living Room Bedroom Gray Overview
Elfzone Window Insulation is presented as an insulated window cover set designed for winter and summer use. The write-up describes thick Oxford fabric with cotton padding (and references cotton filling), and describes the product as blocking 99.9% sunlight while thick cotton layers absorb outside noise.
Instead of a rod-hung grommet panel, installation is described as using included double-sided Velcro, with a zipper closure type listed. The set is described as including an insulated window cover, strong Velcro strips, and installation tools, and the size is listed as 39*70in. The product information section also lists moisture resistance (moisture resistant) and identifies a manufacturer name (Hebei Fengxuan Trade Co.).
Review-pattern notes in the write-up describe room darkening and draft reduction as common themes, while some reviews are described as stating that noise reduction was not noticeable. Where the listing is referenced, the product link is provided for Elfzone, and the same Elfzone listing is referenced again for the insulated window cover context and once more where product info and moisture resistance are discussed via Elfzone.
5. Head-to-Head Comparison: What the Evidence Shows
Blackout and light blocking: Moondream is described as providing 100% blackout and blocking all outside light, while Elfzone is described as blocking 99.9% sunlight and effectively darkening rooms. If the decimal-level difference matters to you, the two write-ups present different stated blackout figures.
Sound-related claims: Moondream includes a specific noise-reduction figure (“up to 10 decibels”) and is described as reducing reverberation in the room, while Elfzone is described as having thick cotton layers that absorb outside noise. Both write-ups also include buyer feedback sections that describe mixed or limited perceived noise reduction for some reviewers.
Insulation framing: Moondream is described as insulating against cold and heat, while Elfzone is described as trapping warmth indoors and reducing cold air leaks by 80%, alongside wind proof and moisture resistant descriptions. The insulation language is similar in intent, but the phrasing and the specific “cold air leaks” percentage claim appear in the Elfzone write-up.
Installation and form factor: Moondream is described as a grommet, ready-to-hang curtain panel intended for a curtain rod. Elfzone is described as a cover set that installs with double-sided Velcro and uses a zipper closure, and the set is described as including installation tools.
Construction and product identifiers: Moondream is listed as polyester with a three-layer build (blackout fabric, thermal lining, thick cotton), and is described as made in Europe with patented technology (U.S. Patent N° 9475260). Elfzone is listed with cotton as the material type and thick Oxford fabric with cotton padding/filling, and includes product information such as item weight (1.16 pounds) and a manufacturer name.

7. Which One May Be the Better Fit for Different Situations
If you want a rod-hung curtain panel with a stated “up to 10 decibels” noise reduction claim and 100% blackout positioning, Moondream may be the more suitable match based on how the panel is described (grommet, ready-to-hang, three-layer build, and a specific decibel figure). This framing may be most relevant when you prefer a traditional curtain installation and want the sound-related claim expressed as a number.
If you prefer an insulated window cover set described as installing with double-sided Velcro and using a zipper closure, Elfzone may be a better fit when that install approach and “window cover” form factor are the priority. The Elfzone write-up also emphasizes a 99.9% sunlight block claim and includes descriptions around reduced cold air leaks (80%) and wind proof/moisture resistant positioning.
For sound expectations, both write-ups include buyer feedback that describes mixed results, so the choice may hinge more on the type of install and the level of claim specificity (decibel figure vs absorption language) than on a guaranteed outcome.
