High Precision Extruded 22mm Polyamide Thermal Break Strips for building facades

Overview

Aluminium windows, doors, and facades are a popular choice for residential and commercial buildings worldwide due to their sleek appearance, modern design, and low maintenance. Aluminium is durable, strong, and corrosion-resistant, ensuring longevity without issues like rotting or warping. However, aluminium is not naturally insulating, so if your windows are made entirely from it, valuable warmth can easily escape from your home.

Aluminium is an efficient conductor of heat and cold, meaning it can lead to significant heat loss or gain through window, door, or facade frames, undermining the performance of double-glazed units. To counteract this, insulation is necessary. Thermal Break technology employs reinforced polyamide profiles (PA66GF25) inserted between the inner and outer aluminium profiles, creating a barrier that slows the transmission of heat, cold, and noise by hundreds of times compared to standard aluminium.

Nowadays, most aluminium windows, doors, and facades are equipped with thermal break strips to minimize heat loss from the frame. Besides enhancing energy efficiency, polyamide thermal break profiles also help regulate indoor temperatures and reduce condensation risks. With thermal conductivity 533 times lower than aluminium alloy, polyamide slows heat transfer, which can lower heating bills by up to 30% and provide a return on investment quicker than the product's expected lifespan. It also improves acoustic performance, boosts thermal comfort, and reduces cooling loads. Additionally, it allows for a color contrast between the inner and outer frames.

The thermal break strips manufactured by Wuhan Yuanfa meet international standards in key technical aspects, with performance exceeding national insulation strip requirements. The product is trusted by leading real estate developers, aluminium profile manufacturers, and door/window producers.
