What is the best material for interior doors

As expert door installers in Markham we know that interior doors are an important aesthetic feature of the house. How they look, how they feel and how they operate can uplift ambience and improve comfort. Though ‘wooden’ doors are understood to be the de facto choice for homeowners across Toronto and the GTA, most are not actually made of wood (or at least not what you would expect to be wood).

Keep reading to find out what the different interior door materials actually used are, the two different types of interior doors (very important) and their pros and cons.

We carry all types of interior replacement doors in Markham. Speak to a representative about our ongoing summer promotions on windows and doors.

Different interior door materials

Wooden interior doors

The classic wooden door is the best option for sound insulation. The natural wood finish is classy and adds a natural look. Buyers can also choose from many different types of lumber from around the world to get the look they want. Depending on the type of wood used, doors can be strong, fire resistant and resistant to dents. People prefer them for their heavier weight compared to other interior doors.

Stamped hardboard interior doors

Hardboard (often referred to by its brand name, Masonite) is a relatively soft material. A hard-baked paint is used to give it strength and improve its durability. Hardboard doors are available as hollow core, filled with foam or particleboard, and have glass inserts. They can be made to a very lifelike wood finish too. That said they can be dented easily.

Medium-density fibreboard (MDF)

MDF is fast becoming a popular choice being stronger than hardboard and more modern looking without costing significantly more. Medium-density fibreboard interior doors are available in a wide range of contemporary styles, making finding something for any aesthetic very easy.


Types of interior doors

Solid core interior doors

Contrary to their appearance, interior doors don’t always have a solid or filled-in core. Doors with solid cores are made of wood, or are laminated with steel and plywood. Fillers can provide excellent thermal insulation, sound insulation and fire resistance.


  • Look and feel solid
  • Good thermal, sound insulation
  • Fire resistant


  • Heavy doors
  • Expensive

Hollow core interior doors

Hollow core doors are light and relatively inexpensive options. Having a hollow core reduces these doors’ thermal insulation, sound insulation and fire resistance.


  • Lighter than solid core doors
  • Easier to install
  • Can be specified with fire resistant materials
  • Affordable


  • Dent easily
  • Not good thermal or sound insulators
