Thermal break insulated aluminum profile is energy-saving special aluminum extrusion material for high-performance doors and windows, curtain wall construction. The profile is divided into inner and outer two independent aluminum cavities, connected and separated by PA66 nylon thermal insulation strips through mechanical rolling compound technology. It cuts off the heat conduction path of metal aluminum, fundamentally solves the heat transfer, cold bridge condensation defect of conventional single aluminum profile. Adopts multi-cavity optimized structural design, with high structural rigidity, excellent air tightness, water tightness and wind pressure resistance reserve. The surface can be processed by electrostatic powder spraying, fluorocarbon coating, wood grain thermal transfer, anodic oxidation and customized popular color finishing. Different series such as 55/60/65/70/75/80/90 series can be customized on wall thickness, section structure and notch structure, matched with sealing…
