Polyamide Strips Blocking Polyamide Strips

Product Description

Product Overview

Heat Blocking Polyamide Strips (also called thermal break strips or thermal insulation profiles) are high-performance structural components engineered to block heat transfer in aluminum assemblies. Made from PA66 GF25 (25% glass fiber-reinforced polyamide 66), our strips comply with European standard EN 14024:2004 and Chinese standard GB/T 23615.1-2017. As a core thermal barrier, they separate inner and outer aluminum profiles in windows, doors, and curtain walls, reducing energy loss by 50%+ while enhancing structural stability. Shuangming Plastic, with 20+ years of manufacturing experience and ISO 9001 certification, delivers precision-extruded strips for global energy-efficient building and industrial applications.
