soundproof Polyamide 66 Extrusion Thermal Insulation Strips for high-rise buildings

Overview

Aluminium windows, doors, and facades are widely favored by homeowners and commercial buildings across the globe due to their sleek, modern design, minimal upkeep, and remarkable strength and resistance to corrosion. These attributes prevent issues such as rotting or warping. However, aluminium does not naturally provide insulation, meaning that if your windows are constructed entirely from this material, warmth within the home can escape.

As a highly efficient conductor of heat and cold, standard aluminium allows significant heat exchange through window, door, or facade frames, ultimately diminishing the effectiveness of double-glazed windows. Therefore, it is essential to incorporate insulation into the frame. Thermal Break technology utilizes reinforced polyamide insulating profiles (PA66GF25) inserted between the inner and outer aluminium layers, creating an insulating barrier that slows down the transmission of heat, cold, and noise by hundreds of times compared to standard aluminium.

Nowadays, thermal break strips are commonly applied to aluminium windows, doors, and facades to reduce heat loss from the frame. Besides offering energy efficiency benefits, polyamide thermal break profiles also help raise indoor temperatures and mitigate condensation risks. With thermal conductivity approximately 533 times lower than that of aluminium alloy, these profiles significantly slow down heat flow, potentially reducing heating costs by up to 30% and providing a faster return on investment than the product’s expected lifespan. Additionally, they enhance soundproofing, improve thermal comfort, and minimize cooling demands. Furthermore, they allow for the inner frame to be finished in a color different from the outer frame.

The thermal break strips produced by Wuhan Yuanfa meet global technical standards and far exceed the national requirements for insulation products. The brand is trusted by leading real estate developers, aluminium profile manufacturers, and door/window producers.
