PU skirting (Polyurethane skirting) is a lightweight, durable trim used at the base of walls to cover the joint between the wall and floor. Typically 4 inches in height, it offers a sleek, modern finish and is resistant to moisture, termites, and warping. PU skirting is easy to install, paintable, and ideal for use in both residential and commercial interiors, especially in humid or high-traffic areas.
