01 / The material
Less weight. A useful door core.
A lighter door-core panel made with hollow channels inside. The tubular design reduces the amount of material used while keeping a board shape.
It is intended for interior door manufacturing where a lighter core is preferred. The whole door, including its frame and faces, must suit the project.
