Quiet Curtains™
Elegant Noise Control.

Custom‑made acoustic drapery that looks as refined as it performs, blocking outside noise (STC‑20) and absorbing reverberation (up to 1.00 NRC).

Premium Sound Control That Adapts to Your Environment

Acoustic curtains are more than just heavy fabric. They are engineered, multi-layered systems that combine absorption, barrier performance, and durability. They are ideal for noisy, high-traffic areas where access and adaptability matter.

Quiet Curtains™ are laboratory‑tested, field‑proven drapery solutions designed to achieve both sound absorption (up to 1.00 NRC) and sound blocking (STC 15, 17, or 20). Combining form and function, they offer elegant aesthetics with serious performance for residential and commercial applications.
These curtain systems are perfect for:
  • Residential & commercial lofts, condos, home theaters, recording studios, vocal booths, dance studios
  • Institutional settings: classrooms, hotels, restaurants, conference rooms, hospitals, patient privacy areas, and more
Whether you need fixed systems or mobile flexibility, our curtain products offer plug-and-play noise control for nearly any space.

Why Memtech’s Sourced Approach Excels

Most companies that sell “soundproof curtains” rely on generic imports with unverified claims. They may reduce a small amount of noise, but rarely deliver measurable results. At Memtech, we take a sourced, engineered approach that ensures you get more than just fabric, you get proven acoustic performance.
What Sets Us Apart:
  • Verified Performance Ratings
    Every Quiet Curtain™ is backed by independent laboratory testing, with certified NRC (absorption) and STC (blocking) ratings. When we say a curtain reduces noise by 17 or 20 dB, it’s not a guess, it’s a measured fact.
  • Customized to Your Space
    Generic drapes don’t account for ceiling heights, window spans, or room acoustics. Our curtains are sized, layered, and styled for your specific project, ensuring a tailored solution that works as designed.
  • Designed for Compliance
    All fabrics are fire-rated for commercial use, making Quiet Curtains™ safe for schools, hospitals, and government facilities where certifications matter.
  • Expert Consultation, Not Just Sales
    As acoustic consultants, we don’t just ship you a curtain, we help specify the right performance level (STC 15, 17, or 20), fabric type, and installation hardware. That means fewer mistakes, less risk, and guaranteed results.
  • Premium Craftsmanship
    Handcrafted in the U.S. with precision stitching and reinforced construction, these curtains are built to last, both in performance and in style.
