Sand Grain Spraying Aluminum Profile for Doors 15 Years Quality Guarantee

Formulated with special infrared-reflective pigments, this coating reflects a significant portion of solar radiant heat, reducing heat absorption by the aluminum profiles. This helps lower the thermal transfer through window and door frames, contributing to improved energy efficiency of the building by reducing cooling loads in summer.

By keeping the interior surface of the frame closer to room temperature, it enhances occupant comfort and helps mitigate the potential for condensation formation on the frame, which can improve indoor air quality and prevent moisture-related issues.

It can be applied as a powder or liquid coating over properly pretreated aluminum. The finish maintains standard weatherability and color stability while providing the added thermal benefit. It is an effective supplementary measure to enhance the overall thermal performance of fenestration systems.
