Germany's Outlast's Aersulate fibre sets new benchmark in insulation

Outlast Technologies GmbH has pioneered a breakthrough in textile insulation by embedding aerogel - a remarkably light and effective insulator - directly into fibers. This innovation significantly enhances insulation properties without adding weight, enabling ultra-lightweight, high-performance apparel. Independent testing confirms that Aersulate-treated fibers provide up to 35% better insulation than conventional ones, setting a new standard in textile technology.

Lightweight, Sustainable, High-Performance: A New Standard for Apparel

The aerogel-rich filling fibers significantly reduces the weight of end products, making it ideal for premium sportswear, jackets, ski pants, and work wear. This is achieved through its exceptionally high aerogel content, which constitutes 50% of the volume. Such a high concentration enables brands to fully utilize aerogels remarkable properties, delivering outstanding performance products.

Unlike conventional insulation materials like foams, wadding, or nonwovens that rely on trapped air for thermal regulation, aerogel encapsulates air within its fiber structure. This allows Aersulate products to maintain their insulating properties even under pressure, where traditional materials often lose effectiveness. As a result, they offer a significant advantage, providing consistent, reliable insulation in high-stress areas such as under backpack straps or at the knees and elbows.

Aersulate technology also supports sustainability: Aerogel is a silicate-based solid derived from quartz sand, which is a natural material, while the fibers are made from wood-based viscose, a renewable and eco-friendly resource.

Outlast Technologies Enhances Comfort in High-Performance Apparel

Combining lightweight design with effective warmth has been a persistent challenge in the apparel industry. “Weight plays a key role in performance clothing,” explains Volker Schuster, head of research and development at Outlast Technologies. “Heavy, bulky jackets can feel uncomfortable and restrict breathability, while lighter options often lack sufficient insulation.”

Now, Outlast has solved this challenge with a patent-pending process that directly integrates aerogel into fibers, a material traditionally difficult to work with. This innovation paves the way for creating products that are both lightweight and highly insulating, opening exciting possibilities for performance apparel.

Independent Testing Confirms 35% Better Insulation

An ISO-certified lab tested the insulation performance of Aersulate-treated viscose wadding against untreated wadding, with results showing a 35% improvement in insulation. This advancement allows apparel to be significantly lighter without compromising warmth, offering a major comfort and performance boost. Schuster concludes, “With Aersulate, we’ve fully harnessed aerogel’s potential for textiles, enabling ultra-light, high-performance, and sustainable apparel that meets growing demands for quality and functionality.”
