What is the difference between timber stud walls and pore concrete?

In Denmark, two common solutions are used for non-load-bearing internal walls. Both systems can divide rooms or create new spaces in a house or apartment.

The choice between a timber stud wall and pore concrete depends mainly on budget, sound insulation, fire safety, and durability. It is also important to consider how easy the wall should be to modify in the future.

Timber stud wall with insulation typically consists of a timber or steel frame filled with insulation, covered with plasterboard. The system can be upgraded with extra layers for improved sound or fire resistance.

Pore concrete wall is a solid construction where aerated concrete blocks are glued or mortared together and finished with plaster or gypsum. This creates a heavier and more robust wall.

Internal wall costs in Denmark (2025)

The cost of building an internal wall depends on materials, finishing, and insulation requirements. In general, timber stud walls are cheaper, while pore concrete offers higher robustness at a higher price.

Timber stud wall with insulation: approx. 600–1,000 DKK per m², depending on insulation quality, fire/sound requirements, and number of plasterboard layers.

Pore concrete wall: approx. 900–1,500 DKK per m², depending on block thickness, finishing, and installations.

Note: These are guideline prices – actual contractor quotes may vary.

Advantages and disadvantages of timber stud walls

• ✅ Usually cheaper than pore concrete
• ✅ Lightweight construction, quick to install
• ✅ Cavities allow easy routing of cables and pipes
• ❌ Requires extra layers for good sound and fire performance
• ❌ Less robust than solid masonry walls

Advantages and disadvantages of pore concrete walls

• ✅ Solid and durable construction
• ✅ Naturally fire resistant and good sound insulation
• ✅ Long lifespan with minimal maintenance
• ❌ Higher material and labour costs
• ❌ Heavier wall – requires sufficient load-bearing capacity of floors
• ❌ More difficult to modify or chase for installations later

When should you choose each solution?

Choose a timber stud wall if budget and flexibility are most important.

Choose pore concrete if the wall needs to be more robust or meet high requirements for sound and fire resistance.

How to optimise internal wall costs

• Request quotes for both solutions for the same m², so you can compare directly.
• Provide clear specifications of insulation, plasterboard layers, and installations.
• Plan electrical and plumbing work in advance to avoid costly changes later.

Conclusion

A timber stud wall with insulation is often the most economical solution for internal walls in Denmark, but pore concrete can be the better choice when sound insulation, fire safety, and durability are priorities. Always obtain actual quotes to assess cost and performance for your project.
