Protect your brandTM
Firegard-knit interliners.

Firegard® knit interliners are made using proprietary core spun yarn technology. We encase a heat-stable core within a sheath of soft comfort fibers to produce flame barriers that drape, feel and breathe like conventional fabrics while offering industry-leading flame retardant performance. We offer multiple widths, basis weights, blends and formats to meet your specifications. Firegard® makes it easy to achieve CFR 1633 compliance without sacrificing your mattresses’ aesthetics. Protect Your Brand™ with Firegard®.

The heart of Firegard® Green is a new fire-resistant TENCEL® fiber, derived from sustainably farmed trees, and made using an environmentally-friendly closed-loop fiber spinning system. But we didn’t stop there.

Firegard® Green is available in a variety of basis weights and constructions – either as socks or as cut and sewn snap-on caps to suit you. Firegard® Green is one more way you can Protect Your Brand™ – and your customers.

Firegard® Green is UL GREENGUARD and UL GREENGUARD Gold Certified, meaning it has been tested for thousands of Volatile Organic Compounds (VOCs) and found not to contribute to poor indoor air quality.
