Thicker doors offer improved sound insulation properties compared to thinner ones. They can help reduce the transmission of noise between rooms, providing a quieter and more peaceful living environment. Thicker doors help to create a barrier against sound and maintain privacy.

●Energy Efficiency
The thickness of a door can impact its energy efficiency. Thicker doors provide better insulation against heat transfer, helping to keep indoor spaces more comfortable and reducing the load on heating or cooling systems. This can result in energy savings and a more environmentally friendly home.

●Security: Thicker doors are generally more secure and offer better protection against forced entry. They are harder to break or kick in, providing an additional layer of security for your home and belongings.
