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

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

A PREMIUM, TECHNICAL TEXTILE SOLUTION THAT REQUIRES NO INSTALLATION WORK

A PREMIUM, TECHNICAL TEXTILE SOLUTION THAT REQUIRES NO INSTALLATION WORK

  • đŸ–€ Total blackout: zero stray light—complete darkness in broad daylight
  • 📉 Noise comfort: up to −28.2 dB* measured in a BELAC/ISO 17025-accredited laboratory
  • ❄ Thermal insulation: up to −44% reduction in heat loss in winter and −33% reduction in solar heat gain in summer, according to EN 14501 — active thermal barrier 12 months a year
  • 🌿 OEKO-TEXÂź certification: tested free of harmful substances — safety guaranteed for the whole family

Performance Plus Satin 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 room's 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 feeling that the outside world is invading your home. Performance Plus Satin is designed to put an end to it—without drilling into walls, without construction, and without waiting.

For best results: hang the curtain as close to the ceiling as possible, extending 20 to 30 cm beyond each side of the opening. The larger the area covered, the more noticeable the effect. When used in conjunction with a roller shutter or double-pane windows, the results can be significantly enhanced.

Our technical report is public and traceable.

Before buying an acoustic curtain, always ask for:

✅ An accredited laboratory report (BELAC, COFRAC, etc.)—not an estimate, not just the fabric weight
✅ The total weight of the assembled curtain in kg/mÂČ—not just the fabric weight
✅ The report number and the standard used — publicly verifiable

The Performance Plus Satin curtain weighs 900 g/mÂČ when assembled. A fabric weight listed in g/mÂČ by a retailer is not the weight of the assembled curtain. The law of mass doesn’t lie: only the certified total weight counts.

* Performance measured in a BELAC-accredited laboratory (Daidalos Peutz, Belgium) in accordance with NBN EN ISO 10140-2:2010. Report No. A-2020LAB-060-I766-44092_E. In-situ performance depends on the installation configuration, the dimensions of the opening, and the perimeter seal. Thermal benefit expressed as the maximum expected gain over single-pane glass according to EN 14501 (fabric alone).
