Choose your Impact / ThermaLoop Insulation

LCA-backed, traceable insulation made from
textile-to-textile recycling.

ThermaLoop circular insulation offers performance, recovery, and thermal efficiency.

Leveraging Textile Takeback^™, a proprietary textile-to-textile recycling process, ThermaLoop is made with 100%* recycled polyester feedstock, with offerings including at least 50% or 100% textile waste content.

Collection of Textile Waste

Post-industrial and post-consumer textile waste — including offcuts, misprints, and end-of-life garments — is collected to begin the recycling process.

001

Sorting & Preparation

Textile waste is graded, shredded, and may be blended with post-consumer plastic bottle flakes to optimize properties and processing efficiency.

002

Resin Production with Traceability

Powered by our proprietary Textile Takeback^™ recycling system, the shredded textile waste is melted and transformed into high-quality recycled polyester resin. Our FiberPrint^® technology is embedded at this stage to ensure full traceability and product integrity.

003

ThermaLoop^™ Insulation Production

The resin is used to produce specialized fiber that is converted to ThermaLoop insulation — a fast-drying, lightweight thermal insulation offered in down-like fiber, fiberball, and padding.

004

Backed by third party reviewed LCA data, ThermaLoop insulation demonstrates over a 42% reduction in GHG emissions, up to a 69% reduction in energy consumption, at least a 48% reduction in fossil fuel consumption, and up to a 71% reduction in freshwater consumption, over virgin polyester production.¹
