Performance PLUS Woven Soundproof Curtain – Lab-Tested: -28.2 dB*

Tested by a BELAC-accredited laboratory · 1.35 kg/mÂČ Â· 4 layers · M1 · Oeko-TexÂź

Everyone else shows dB.
We have the lab report.

The NOKOMIS Performance Plus curtain is a multi-layered technical fabric designed to provide lasting improvements in acoustic, thermal, and visual comfort in a room exposed to disturbances—with a natural and elegant braided finish. Tested by an independent, accredited laboratory. M1-rated. No installation work required.

Patented technology (EP3 440 965): engineered multilayer composite with sound attenuation measured at up to −28.2 dB* in the laboratory (Daidalos Peutz · BELAC / ISO 17025 · ISO 10140-2 standard). Braided finish on both sides.

A PREMIUM, TECHNICAL TEXTILE SOLUTION THAT REQUIRES NO INSTALLATION WORK

đŸ–€ Total blackout: zero stray light — complete darkness in broad daylight

📉 Noise level: up to −28.2 dB* measured in a BELAC/ISO 17025-accredited laboratory

❄ Thermal insulation: up to −44% reduction in heat loss in winter, −33% reduction in solar heat gain in summer (EN 14501) — active thermal barrier 12 months a year

đŸ”„ Safety: M1 fire rating — industry standard

🌿 Oeko-Tex¼ certification: tested for harmful substances — safety verified for the whole family

Performance Plus is designed for people who want to make a bedroom, living room, bay window, or doorway more comfortable in the face of everyday nuisances—without changing the layout.

Unlike a traditional curtain that is simply thick or blackout, NOKOMIS weight, thickness, a multi-layered design, a premium finish, and performance tested by an accredited independent laboratory. The goal is not just to dress a window—it’s to transform the perceived comfort of the room.

Noise is exhausting. It causes fatigue, disrupts sleep, makes working from home a struggle, and creates the impression that the outside world is invading the inside. Performance Plus is designed to seriously address this issue—not to merely mask the problem.

What really makes a difference in a room’s comfort isn’t just the thickness of the fabric. It’s the combination of the multilayer design, full coverage of the opening, and careful installation. A curtain that’s too short—installed inside a window opening without extending beyond it, with an untreated roller shutter box above it—lets in a significant amount of noise and light, regardless of the fabric’s thickness. Performance Plus is designed to ensure that all three of these conditions are met.

đŸ”„ M1 fire rating: the standard for demanding professionals.

The M1 rating is the fire-resistance standard required in public buildings, hotels, offices, and commercial spaces. This is not just a minor detail—it’s a practical requirement that not all e-commerce curtains have yet met. Performance Plus has met it.

This report exists. It has a reference number. It comes from an accredited independent laboratory. You can request it—no one can make it up.

Compare the evidence, not just the numbers.

Many soundproof curtains prominently display their dB ratings. But before comparing numbers, ask yourself a simple question: Where does that number come from? Which independent laboratory? Which testing standard? What is the report number? Is the fire rating M1? What is the total weight of the assembled curtain in kg/mÂČ?

A figure that doesn't answer these questions is merely an intended performance, not a measured performance. Even the cheapest curtain becomes expensive the day it fails to improve your comfort.

A curtain made of 300–400 g/mÂČ of fabric ≠ a curtain weighing 1.35 kg/mÂČ when assembled, as tested in an accredited laboratory. The law of mass doesn't lie.

Before buying, compare the specifications: laboratory testing, certification, testing protocol, fire rating, weight, dimensions, and actual conditions of use. Read our guide on soundproof curtains for €89. To learn more: understand the Rw rating and the test report.

When you choose NOKOMIS, you're choosing a reliable, elegant, and hassle-free solution to permanently improve the acoustic and thermal comfort of your home.
