Introduction
Natural daylight and street lighting can disrupt indoor rest and work environments. Ordinary curtain fabric cannot block strong light completely.
Blackout curtain fabric is a high-density textile material. It designed to block visible light and reduce outdoor light penetration.

It achieve full light blocking at lower cost. But the coating layer may wear or crack after frequent washing.
Heavy-Duty High GSM Blackout Fabric
High GSM blackout curtain fabric adopts dense weaving method. It has thicker texture and higher fabric weight.
This material provide better sound insulation and temperature control. It suit high-standard bedroom and hotel usage.
Fabric Performance & Specification Comparison
Light blocking rate, fabric weight and thermal performance are the core evaluation standards. The table below shows verified 2026 professional textile test data for mainstream blackout curtain fabric types.
Fabric Type | Light Blocking Rate | Typical GSM | Temperature Reduction | Sound Attenuation | Wash Resistance |
Triple Weave Blackout Fabric | 95% - 99% | 200 - 300 | 4 - 6°C | 12 - 18 dB | Excellent |
Acrylic Coated Blackout Fabric | 99% - 100% | 200 - 350 | 5 - 7°C | 15 - 20 dB | Average (easy peel) |
High GSM Heavy-Duty Fabric | 99.9% | 320 - 400 | 6 - 8°C | 18 - 22 dB | Very Good |
Ordinary Room Darkening Fabric | 80% - 90% | 180 - 220 | 1 - 3°C | 3 - 7 dB | Good |
