Why Fiberglass

IT'S THE CORE DIFFERENCE

The Material Matters.

Our fabrics are built different. At the heart of a Mermet fabric is fiberglass, a core yarn made from naturally occurring materials like silica sand and calcium and chosen for its exceptional strength and stability. Fiberglass is 25% stronger than polyester and won’t stretch, shrink or twist over time, helping your shades hang straighter, track better and look beautiful for years to come.

Protected by a durable vinyl coating, the fiberglass core delivers the lasting performance Mermet is known for.

Because a better shade starts at the core.

Clearer Views. Fewer Service Calls.

Think of it like pixels on a screen, the finer the detail, the sharper the image. Mermet’s thinner fiberglass core yarn delivers a crisp, high-resolution view while still providing comfortable shade and glare control.

The thinner, lighter fabric also creates a smaller roll-up diameter and puts less load on motors and hardware, supporting reliable performance over time and helping reduce service calls.

The result is a clearer view with less demand on the shade system.

The Core Difference Is Clear.

From clearer views to lasting performance, fiberglass delivers distinct advantages in roller shade fabrics, but its benefits don’t stop there. Fiberglass is inherently fire resistant, with a melting point three times higher than polyester, bringing an additional level of performance to the core of Mermet fabrics.

Mermet takes that commitment even further. Our fabrics meet GREENGUARD Gold indoor air quality standards, pass antibacterial and antifungal testing, and are easy to clean. Select fabrics also feature our SFR™ (Safe + Flame Retardant) certification, providing an added level of product safety and transparency.

From the view to the performance, the difference is at the core.
