Flush Doors

Doors are not only essential for privacy and security, but form integral parts of the structure and design of a space. Doors need to be durable, impenetrable, resistant to water, insects and extreme weather conditions and must not change their shape, or warp, over time.

A flush door, named so because of its smooth, seamless surface, is composed of a pre-fixed timber frame (comprising horizontal rails and vertical stiles) with a solid block board type core sandwiched between two or more layers of veneer on either side. The door is then covered with decorative face veneer for aesthetic value.

With a solid core construction and built to last - National Flush Doors are manufactured with rigorous standards of wear and tear. National Flush Doors have immaculate design, structural strength and superb dimensional stability.Our doors stand the test of time.
