If you’re planning an interior door replacement, one of the first decisions you’ll need to make is whether to choose solid core or hollow core internal doors.
Although they may look similar from the outside, the construction of each door makes a significant difference to durability, sound insulation, weight, cost and long-term performance.
In this guide, we’ll explain the key differences between solid core vs hollow core internal doors to help you choose the right option for your home.
What Is the Difference Between Solid Core vs Hollow Core Internal Doors?
Understanding solid core vs hollow core internal doors starts with knowing how each door is constructed.
A solid core door has a dense engineered timber core finished with a veneer or painted surface. This gives the door greater strength, improved acoustic performance and a more substantial feel.
A hollow core door isn’t completely hollow. Instead, it contains a lightweight honeycomb or lattice structure inside a timber frame, making it lighter and more affordable.
Both have their place depending on your budget, the room you’re upgrading and how you use the space.
Why Choose Solid Core Internal Doors?
Solid core doors have become the preferred choice for many homeowners because they offer a premium feel and excellent long-term durability.
Benefits include:
- Better sound reduction between rooms
- Greater strength and resistance to knocks
- More substantial feel when opening and closing
- Longer lifespan
- Better quality appearance
If you’re renovating your entire home or investing in a long-term interior door replacement, solid core doors usually provide the best overall value.
Our range includes several solid core options, including the Pre-finished Carini, Pre-finished Mexicano, Oak Full Glazed Mexicano, Vancouver Long Light and White Mexicano doors.
The Timber Research and Development Association (TRADA) also provides technical guidance on the performance of timber doors, including factors such as construction, durability and fire performance, making it a useful independent resource for homeowners wanting to learn more before choosing new internal doors.
When Are Hollow Core Doors a Better Choice?
When considering solid core vs hollow core internal doors, solid core doors are often seen as the premium option, however, hollow core doors still have advantages.
They are:
- More affordable
- Easier to lift and install
- Suitable for lower-use rooms
- Available in a wide range of styles
If you’re working to a tighter budget or replacing doors in spare bedrooms, cupboards or utility rooms, hollow core doors can provide an attractive and practical solution.
Our 6 Panel and Dordogne internal doors are examples of hollow core options that offer excellent value without compromising appearance.
Solid Core vs Hollow Core Internal Doors: Which Is Better for Your Home?
When comparing solid core vs hollow core internal doors, there isn’t a single right answer.
Choose solid core if you want:
- Better privacy
- Reduced noise
- Premium quality
- Long-term durability
- A higher-end finish
Choose hollow core if you want:
- Lower initial cost
- Lightweight doors
- A practical solution for less frequently used rooms
Many homeowners actually choose a combination of both, using solid core doors in living areas and bedrooms while fitting hollow core doors in cupboards or secondary spaces.
Is It Worth Upgrading During an Interior Door Replacement?
If you’re already replacing your internal doors, it’s worth considering whether upgrading to solid core doors is the right investment.
Because the labour involved in fitting either type is broadly similar, many homeowners decide the additional cost of a solid core door is worthwhile for the improvements in quality, durability and sound insulation.
Professional measuring and fitting also helps ensure each door operates correctly and provides a high-quality finish.
Choosing the Right Style
Construction is only one part of choosing new internal doors.
You’ll also want to think about:
- Modern or traditional designs
- White or oak finishes
- Glazed or solid panels
- Matching doors throughout the property
Whether you’re looking for contemporary styles or timeless classics, choosing doors that complement your home’s interior creates a much more cohesive finish.
