Life Expectancy and Maintenance

Palladio Composite doors require little to no maintenance and are incredibly durable. Their durability means they are guaranteed to last for many years in tip top condition. They are designed to have a natural look with some of the features typical of a timber door. The materials used are combined in such a way that the end result is a remarkably durable door. Unlike other types of doors that are more susceptible to the elements and ageing, they will not dent, warp, bow or twist.


One of the most amazing features about composite doors is how strong and secure they are. Our doors have a multitude of security features that make them rock solid. A unique monocoque structure gives our Palladio doors it’s amazing strength. These doors, aside from being very attractive, are also heavy duty. In contrast to doors that possess a foam core, they cannot be easily pried open or destroyed. They are virtually unbreakable and nearly impossible for any intruder to break through.
