Hollow Core

What is Hollow Core

Definition of Hollow Core in Construction

The term hollow core is normally used to describe a construction product that has a core that is not filled. For example a hollow core door, is a door that is a molded shell of material, such as vinyl or fiberglass and is not filled with anything other than air. This method of construction allows the product to be exceptionally light and strong, but does not provide any real insulation or fire rating capabilities. Any construction product that is considered hollow core is usually manufactured in this manner to minimize weight as well as cost. If a roofing panel is hollow core, the panel will be extremely light, but will not offer substantial sound, fire or temperature resistance.
