The choice of interior door material is the main criterion for its quality. It is on the choice of material that such important parameters as cost, wear resistance, and appearance will depend. Let’s take a look at the main door core types and their distinctive features.
What Is a Door Core?
It is a core that is placed inside the door to provide either strength or fire rating. You can choose interior doors from the four-door core options, which are distinguished by the greatest practicality and ease of use. It should be noted that all options are almost the same in terms of convenience; nevertheless, each design has its own characteristics.
Different materials are used for door production. Depending on the price, a door leaf with different core structures can be used. They are structurally divided into the following groups. Each core type has benefits and specific applications where they are recommended or even required to be used.
Hollow Door Core
Hollow-core doors are constructed with a thin layer of fiberboard or wood applied over a plastic or honeycombed cardboard core. There are two available options:
- Honeycomb door core – A honeycomb core door comes with a pattern of cardboard or fiberboard to pack the space between two boards, providing structural support to the door;
- Hollow door core – Hollow core doors are not completely hollow; they come with a cardboard honeycomb inside.
The smart core is a modern innovative material for thermal and acoustic insulation, which is produced with the use of wood and environmentally friendly components. Different from the honeycomb door core, the solution allows for effective thermal and acoustic insulation.
Particleboard wood door cores are made of ground-up raw wood glued together to form the core. Particleboard is very durable and cheap.
Structural Composite Lumber
Structural composite lumber is a durable, environmentally friendly material with high wear resistance. Its structure imitates natural wood with 100% accuracy; it does not change its color or crack during use. The best thing about such doors is that their price is lower compared to analogs available on the market today.
A stave-core door is made by gluing veneer to a built-up core consisting of blocks or strips of wood that are from the same species. Stave lumber core doors are durable, lightweight, and fail-safe. They fit into any premises and are easy to arrange.
Fire-Rated or Mineral Door Core
Fire-rated doors are required for key areas in schools, hotels, and most other public spaces. There are some requirements for such door constructions. Fire-rated cores, also known as mineral cores, are made from non-combustible materials such as minerals and fiberglass. Such a core structure slows the spread of smoke and fire from one premise to another, which is the main distinctive feature of the core type.
