T-molding is a type of trim used to cover the seams between two flooring surfaces, such as laminate and carpet. Its shape resembles the letter "T," which allows it to fit snugly over the joint, providing a smooth transition while protecting the edges of the flooring. This molding is available in various materials, including wood, vinyl, and metal, making it suitable for different styles and environments. T-molding is commonly used in both residential and commercial spaces, enhancing the aesthetic appeal while ensuring durability and stability at the junction of different flooring types.
