Understanding the Differences Between Silent Gliss Corded Curtain Tracks

When specifying curtain tracks for residential or commercial projects, selecting the correct Silent Gliss system can have a major impact on installation efficiency, curtain performance and long-term reliability.

For trade professionals, it’s not simply about choosing a “curtain track”, it’s about selecting the correct profile strength, operating style, wave compatibility and bending suitability for the environment.

Silent Gliss offers several corded systems, each designed for different applications, fabric weights and installation requirements. This guide compares the most commonly specified systems used across residential, hospitality and commercial interiors.

The comparison chart below highlights the key differences between the Silent Gliss SG3000, SG3840, SG3870, SG3900, SG3970 and SG6370 systems.

Choosing the Right Silent Gliss Hand-Drawn Track

For trade professionals, the correct specification usually comes down to four key considerations:

• Curtain weight
• Required track length
• Whether wave curtains are needed
• Whether bending or curved installations are required

For lightweight residential projects, the SG3000 remains a strong entry-level option.

For contemporary wave curtains, the SG3840 and SG3870 are regularly specified.

Where heavier fabrics or longer spans are involved, the SG3900 and SG3970 offer increased performance.

For demanding commercial applications, the SG6370 provides the highest carrying capacity within the hand-drawn range.
