Industrial Aluminum Extrusion Insulation Fittings Manufacturer

Thermal break strips are not only connectors but also critical structural components. Therefore, the selection of thermal break strips is not limited to just being excellent thermal insulation materials; it is essential that their strength and aging resistance meet the requirements of aluminum alloy doors and windows, allowing them to withstand long-term erosion from outdoor natural environments, ensuring safe use. Poor-quality thermal break strips not only fail to achieve the technical objectives but also cannot guarantee safety performance during use, potentially leading to safety accidents. The cost of thermal break strips accounts for less than 5% of the cost of insulated aluminum alloy doors and windows, yet they affect 80% of the safety performance of the doors and windows. The thermal break strips used in the market include nylon thermal break strips and PVC thermal break strips. Calculating per square meter, nylon thermal break strips are over 10 yuan more expensive than PVC thermal break strips. However, PVC thermal break strips are more commonly used in the market. Due to customers' lack of understanding of broken bridge aluminum doors and windows, they tend to seek cheaper options, while businesses, in pursuit of profit, use PVC thermal break strips instead of nylon thermal break strips. Nylon strips provide thermal insulation, heat retention, and sound insulation. They are heat-resistant and non-combustible. Nylon thermal break strips can prevent gaps between the thermal break strip and metal due to thermal expansion and contraction. In contrast, PVC thermal break strips may create gaps between the thermal break strip and the metal due to thermal expansion and contraction, failing to achieve the desired insulation effect, and thus cannot be considered as part of broken bridge aluminum doors and windows.
