19.5mm Extruded Polyamide Operating Rods for Windows

Overview

The development of building doors and windows has transitioned from early single-glass wooden and solid steel designs to more advanced options like hollow steel, aluminum alloy, and plastic steel windows. Today, energy-efficient solutions such as thermal break aluminum alloy, double-glass wooden, and aluminum-wood composite windows dominate the market. Aluminum alloy frames are valued for their durability, lightweight structure, high strength, fire resistance, and aesthetic appeal. However, they have poor insulation due to high thermal conductivity. To address this, manufacturers have introduced "thermal break aluminum," a technology that has seen rapid adoption, growing approximately 10% annually. The core of this technology is the polyamide insulating strip, which significantly impacts the thermal efficiency and energy-saving performance of modern aluminum windows and doors.

Buildings lose about one-third of their energy through doors and windows, but thermal breaks—accounting for only 4% of window costs—can enhance insulation efficiency by 20%-30%. These strips act as a barrier between interior and exterior frames, reducing heat transfer. Made from polyamide fiberglass, they are effective in blocking thermal conduction and are widely applied in both standard windows and glass curtain walls to meet energy-saving demands.

Aluminum doors, windows, and facades are favored for their sleek design, strength, and resistance to corrosion or warping. However, as aluminum alone is a poor insulator, polyamide strips are now standard, helping to retain indoor heat, prevent condensation, and improve overall energy efficiency.

Since 2003, Wuhan Yuanfa has prioritized energy-efficient building solutions by introducing advanced technology and collaborating with top universities in Wuhan to develop polyamide insulating strips. These products have earned widespread recognition for their quality and innovation, receiving accolades such as the "National Torch Plan Project" designation and being honored as a high-tech enterprise.
