Flush doors are flat, smooth doors that have a simple and clean design. They are typically made from a solid core or hollow core material, which provides strength and insulation. The surface is usually covered with a veneer or laminate, making them suitable for various interior styles. These doors are commonly used in residential and commercial buildings due to their versatility and affordability. Flush doors can be painted or stained to match any decor, and they are easy to install. Their minimalist appearance makes them a popular choice for modern spaces, enhancing the overall aesthetic without being overly decorative.
