Solid core vs hollow core doors – which is better?

Depending on your door needs, you may have heard the term ‘hollow’ or ‘solid’ core before. This refers to the internal makeup of the door and determines its suitability for different environments.

Many industrial doors in the market today are hollow core doors. This means that the inside is usually a honeycomb design known as honeycombed cardboard. The rest is a ‘wood shell’. Typically, they are used in interior applications due to their reduced stability.

While cheaper to manufacture, they are not very good as exterior doors. The honeycomb cardboard interior means the door will have less solidity and strength, so it shouldn’t be subject to harsh conditions, such as the weather. It may also be more susceptible to break-ins.

Solid core doors are made from engineered wood with real wood veneer, whereas solid wood doors are made from a frame and panel. Larnec’s range of solid core doors and solid wood doors are fully metal clad with double door skin.

This means that the doors are reinforced with metal sheets making them exceptionally strong, durable and better at insulating noise and temperature.

Solid core door main benefits

Solid core doors and solid wood doors are a far safer and more secure option, especially for exterior use. Larnec’s range of industrial solid core and solid wood doors provide maximum protection and durability. The main benefits of solid core or solid wood doors are:

  • Heavier and denser (stronger)
  • Excellent insulation capability
  • Enhanced noise reduction ability

To learn more about these benefits, read below!

Solid wood doors and solid core doors are better for acoustics

A solid wood door or solid core door is going to give you a much better acoustic performance than a hollow core door. A solid door disrupts sound waves making it much more effective at muffling sound and extraneous noise.

If sound insulation is important, selecting a solid door with dense materials will be more beneficial. Hollow doors in comparison are structurally weak and best applied only to environments with minimal noise or impact from the elements such as wind and rain.

When it comes to acoustics, it’s a no-brainer between solid core vs hollow core doors. If you’re interested in learning more, speak to our friendly customer service team who are more than happy to assist you.

Heat insulation performance with solid cores

Solid core doors can aid a variety of applications including home offices, industrial buildings, warehouses, sheds, garages and more. This is especially true in environments with extreme weather conditions such as Australia.

Solid core doors are well ahead of other doors

When you’re facing harsh hot or cold temperatures, solid core doors are going to make a big difference. In winter, solid doors are going to reduce heat loss, retain more heat and withstand temperature changes.

In summer, they will keep in the cold and insulated from the heat. This also means little maintenance is required as solid core doors are sturdy and long-lasting.

A hollow core door is going to offer little insulation and protection from temperature changes throughout the seasons. Much like a home’s interior, you want to lock in the hot or cold which hollow cores will struggle to do.

Solid core doors and security

Not only do solid core doors offer excellent acoustic and temperature insulation, but they also offer enhanced security. The metal cladding provides enhanced protection from sound and temperature while also adding solidity to the door structure.

With a solid interior, it’s much harder to break down or damage solid core doors in the event of a break-in or harsh weather.

Larnec also has a range of lock options to further enhance security. There are many different types of locks available for industrial metal-clad doors, which all work in different ways and have their own advantages.

Lock types:

  • Deadbolt
  • Mortice
  • Panic bar
  • Knob locks
  • Lever
  • Jimmy Proof Deadbolts
  • Latch Locks
  • Padlocks
  • Cam Locks
  • Wall Mounted Locks

Frequently asked questions

Are solid core doors better than hollow doors for industrial and commercial use?

Solid core doors are generally better suited for industrial and commercial use due to their strength, durability, and acoustic performance. They are designed to handle higher traffic and harsher environments, whereas hollow doors are typically suited for low-impact internal applications. For sites requiring added protection, solid core options can also support configurations similar to security doors.

When should I choose a hollow door over a solid core door?

Hollow doors are suitable when cost, weight, and basic internal separation are the main priorities. They are commonly used in low-traffic areas such as offices or internal partitions where durability and security are less critical. However, they are not designed to support heavy-duty hardware or high-impact use.

Do solid core doors provide better fire resistance than hollow doors?

Solid core doors can offer better fire resistance when specifically designed and tested for that purpose. Their dense construction allows them to support fire-rated configurations, unlike hollow doors which typically lack this capability. For compliant installations, it’s important to consider purpose-built fire doors that are tested to Australian standards.

How do solid and hollow doors compare for security and access control?

Solid core doors provide stronger security and are more suitable for access control systems. Their construction allows for more robust locksets, hinges, and reinforcement, making them a better fit for controlled entry points. Hollow doors may not reliably support advanced locking systems or anti-burglary hardware often used in security door applications.

Which door type is better for sheds, warehouses, or external applications?

Solid core doors are better suited for sheds, warehouses, and external applications due to their durability and resistance to environmental conditions. They are designed to handle wind, impact, and frequent use, making them a practical choice for industrial settings. Hollow doors are generally not suitable for external use as they can degrade faster and offer limited structural performance.
