Soundproof Curtains: How to Check Reviews Before Buying?
A soundproof, thermal, or blackout curtain is rarely a trivial purchase. People buy them because there’s a real problem to solve: outside noise, a room that’s too bright, a room that’s too hot, drafts, or a need for privacy or comfort.
And that is precisely why we need to be vigilant. As soon as a product promises comfort, performance, and a very attractive price all at once, it also attracts dishonest sellers, very new websites, copied product descriptions, customer reviews that are hard to verify, and technical claims that are sometimes vague.
Before making a purchase, the right approach is not to rely solely on the product page. The right approach is to check the brand, its history, independent reviews, and the actual quality of customer feedback.
Why Reviews Posted on a Website Aren't Enough
Customer reviews displayed directly on a store's website can be helpful, but they should never be your only source of trust.
An e-commerce site has some control over its environment: product pages, photos, text, selling points, featured testimonials, reassurance elements, and sometimes even the order in which reviews are displayed. This doesn’t mean that all these reviews are fake. It means they need to be cross-checked.
When making a technical purchase—especially when it comes to soundproof curtains—you should look elsewhere: independent review platforms, the website’s track record, clarity of return policies, quality of customer service, consistency in delivery times, accuracy of acoustic claims, and overall transparency.
The first thing to do: go to Trustpilot
Trustpilot isn't perfect, but it's a useful tool because it lets you compare several metrics in one place: overall rating, number of reviews, rating distribution, recent reviews, responses to negative reviews, whether the business has claimed its profile, and information on how the business collects reviews.
Don't just look at the rating. A rating of 4.8 with very few reviews may be less reassuring than a lower rating based on many detailed reviews. Conversely, a low rating with few reviews can be a red flag, but it should also be interpreted with caution.
The most important thing is the body of evidence.
The detail that many customers overlook: the profile of the person leaving the review
When you read a review, don't just look at the stars. Take a look at the reviewer's profile, too.
A 5-star review posted by a user who has left only one review on the entire platform does not carry the same weight as a detailed review posted by someone who has made several purchases. This isn’t proof of a fake review. But it is a weak indicator worth considering, especially if many positive reviews are similar, very short, very enthusiastic, and come from profiles with only one review.
Conversely, an isolated negative review should also be viewed with a grain of salt. What matters is the overall trend: Are multiple customers describing the same issue? Is the company responding? Are the responses concrete? Do the reviews actually address the product received, delivery times, dimensions, or customer service, or are they vague?
For a technical curtain, a helpful review often includes details such as: installation type, dimensions, fabric quality, light-blocking ability, acoustic performance, turnaround time, interactions with customer service, and the solution offered in case of a problem.
Example of a public audit
As of June 24, 2026, several Trustpilot pages in the curtains and soundproof curtains sector show significant differences between brands. This data changes over time; therefore, it should be verified again before making any purchase.
| Brand or website | Public review found on Trustpilot | Key Takeaways |
|---|---|---|
| The Curtain House | Low TrustScore, 2.3/5, 8 reviews, profile not claimed at the time of viewing. | Few reviews and a low rating: this isn't definitive proof, but it's a red flag that should prompt you to do some very thorough research before buying. |
| Moondream | Average TrustScore: 3.7/5, 57 reviews. The page also shows a significant number of 1-star reviews. | A well-known brand, but reviews are very mixed: be sure to read the negative reviews, particularly those regarding customer service, product dimensions, returns, and sound quality. |
| Sound Escape | Higher rating and a much larger volume of reviews than many other companies in the industry. | The volume of reviews provides more material to analyze, although it’s still important to read the detailed experiences and check the authors’ profiles. |
| NOKOMIS | High TrustScore based on a larger volume of reviews than many smaller niche sites. | Positive sign: Reviews provide a solid basis for evaluating the quality of advice, follow-up, and products. However, it’s important to continue reading the details of people’s experiences. |
| Cotton Silence | The number of Trustpilot reviews on the dedicated page was still limited at the time of this review. | Cotton Silence should be viewed within the context of its ecosystem: a brand specializing in technical curtains, backed by NOKOMIS, with a professional line—Cotton Silence Pro—used for B2B projects, architects, offices, restaurants, hotels, and public spaces. |

Google, internal reviews, social media: useful, but not enough
Google reviews can be helpful, especially for a local business with a physical address, a recognizable team, and customers it has actually served. But for an online store, they don't always tell the whole story.
A customer should ask themselves a few simple questions:
- Are the reviews recent and detailed?
- Did the authors publish multiple reviews, or just one?
- Do the reviews actually discuss the product that was purchased, or just a vague experience?
- Are there any negative reviews visible?
- Does the company address issues clearly?
- Do the same phrases come up often?
- Does the website provide an address, a real identity, and clear return policies?
A reputable brand doesn't necessarily have nothing but perfect reviews. Above all, it must be recognizable, consistent, accessible, able to explain its products, and honest about their limitations.
Warning Signs to Watch for Before Buying a Soundproof Curtain
Here are the things to check before placing an order.
1. Acoustic promises that are too good to be true
A soundproof curtain can improve comfort, reduce some noise, and limit certain types of sound transmission. But it does not turn a lightweight window into an acoustic wall. Be wary of miraculous promises, especially if they are not accompanied by clear explanations regarding installation, overhang, the track, weight, scope, and limitations of the product.
2. A very low price for very high performance
Acoustic performance requires the right materials, weight, craftsmanship, and proper installation. A curtain advertised as high-performance, highly technical, custom-made, delivered quickly, and sold at an unusually low price should be viewed with caution.
3. Photos that are too generic
The images may be attractive but may not accurately represent the product you receive. Check to see if the website shows actual details: drape, thickness, high-quality finish, lining, pleats, grommets or ruffles, recommended track, and examples of installations at customers' homes.
4. Vague return policies
Custom curtains often come with specific conditions. That’s normal. What’s less normal is the lack of clarity regarding returns, refunds, delivery times, measurement errors, or any potential fees.
5. Customer service that is hard to reach
Before making a technical purchase, you should be able to ask a simple question and receive a clear answer: What width should you choose? What type of installation—track or rod? What overhang? What are the acoustic limits? What finish? If the answer is vague, that’s not a good sign.
The 5-Minute Test Before You Order
Before buying a soundproof curtain, take five minutes to do this test:
- Search for the website name + “Trustpilot”.
- Take a look at the rating, but especially at the number of reviews.
- Open a few positive reviews and check the authors' profiles.
- Be wary of a cluster of very short 5-star reviews from profiles with only one review.
- Read the 1-star and 2-star reviews.
- Check to see if the company responds to negative reviews.
- Check how long the website has been online and verify the company's identity.
- Please read the return policy before paying.
- Ask customer service a simple technical question.
If several red flags appear at the same time, the risk increases: a low rating, few reviews, a new website, vague promises, unclear feedback, customer service that’s hard to reach, generic photos, prices that are too good to be true, or positive reviews that are too similar, posted by profiles with very little activity.
Why Cotton Silence and NOKOMIS emphasize this point
Cotton Silence is not just another generic brand that was created solely to sell curtains online. It is a brand specializing in technical curtains, supported by the NOKOMIS ecosystem, with a professional line— Cotton Silence Pro—designed for architects, specifiers, businesses, hotels, restaurants, offices, and commercial spaces.
This difference matters. A technical curtain is more than just a pretty picture and a promise of a certain decibel level. The result depends not only on the product, but also on the dimensions, the type of installation, the track, the overhang, the height, the width, and the actual problem to be addressed.
At Cotton Silence, we prefer to clearly explain what a curtain can do—and what it can’t promise on its own. It’s less spectacular than a magical promise, but it’s more honest and more helpful to the customer.
With NOKOMIS, customers also benefit from a well-known brand, publicly available reviews, a track record, and genuine product advice. These are the factors to look for before ordering a soundproof, thermal, or blackout curtain: a clear brand, recognizable expertise, accessible reviews, and a service team capable of helping you make the right choice.
Before you order, compare your options. Read the reviews. Look for red flags. Check the authors' profiles. Review the terms and conditions. And if you're unsure about the right solution for your window, bedroom, office, or door, ask for advice before you pay.
