Duofor floor vs Compofloor
A Duofor floor is often mentioned as an alternative for replacing ground floors in existing homes. Like other combination and cassette floors, Duofor focuses on renovation projects where traditional concrete floors are less suitable. However, there are clear differences in construction, installation, and load-bearing capacity that make a significant difference in practice. When comparing these floor systems, it's easy to see why Compofloor is becoming increasingly popular in renovation projects.
What is a Duofor floor?
The Duofor floor is a combination floor in which the supporting structure against the foundation is installed. The floor is constructed from multiple layers and requires a relatively large number of actions on the construction site. In practice, the construction is very similar to systems like the Havebo and SL combination floors, where assembly and finishing take place largely on-site. This makes the system versatile, but also more sensitive to variations in construction, subfloor, and installation quality.
Construction difference: against the foundation versus in the foundation
An important difference between Duofor and Compofloor is the way the floor is supported.
At Duofor:
Compofloor uses an anchor in the foundation, which distributes forces evenly. This is a major advantage, especially with older foundations, as it prevents point loads and stresses.
Assembly, labor and inconvenience
Duofor requires:
This means longer lead times and a greater risk of disruptions in occupied areas. Compofloor is delivered prefabricated and installed cleanly, which significantly shortens the renovation time and minimizes disruption.
Load-bearing capacity and technical performance
Although Duofor is technically comparable to other composite floors, its load-bearing capacity and structural robustness remain more limited than those of Compofloor. This plays a crucial role in renovations where reliability and future-proofing are important.
Compofloor is designed for long-term use in existing buildings, offering greater flexibility for comfort, finish, and usability.

Why Compofloor is increasingly preferred in renovation projects
In theory, both systems are applicable, but in practice, Compofloor demonstrates the key difference. Thanks to its anchoring in the foundation, its prefabricated design, and higher load-bearing capacity, Compofloor is better suited to existing homes with older foundations.
While Duofor resembles traditional combination floors with additional on-site steps, Compofloor was developed as a complete renovation solution with minimal risks, shorter lead times, and greater structural reliability.
How does Compofloor work in practice?
You can compare floor systems on paper, but it helps to see how they're constructed in broad terms. What does a renovation floor actually look like? And what happens during installation? This animation gives you a clear overview of Compofloor's construction. You'll see how the floor cassettes are installed, how the system connects to the existing foundation, and how the new ground floor is constructed step by step. Seeing how the system is constructed makes it clear why this solution is often a logical and foundation-friendly alternative to heavier or wet construction methods in renovations.
Which floor suits your home?
The right choice always starts with the existing foundation and floor structure. In renovation projects where speed, reliability, and foundation-friendliness are paramount, Compofloor often proves to be the most logical and future-proof solution.
Want to know which floor is best suited to your situation? The first step is to assess the existing ground floor and foundation. This allows us to determine which solution is most suitable technically and practically.
Frequently asked questions about Duoflor flooring
What is the risk of a floor that lies against the foundation instead of in it?
When a floor such as Duofor is placed against the foundation, there is a risk of point loading, which can lead to cracking or subsidence in older foundations.
How important is even force distribution during floor renovation?
An even distribution of forces – as with Compofloor – prevents stress points at weak spots in the foundation and contributes to the long-term stability of the floor.
Why does a Duofor floor create more construction waste than a Compofloor?
Because many components have to be processed and disposed of on site, more sawing, packaging and landfill waste is generated than with a prefabricated system.
Is a Duofor floor also suitable for crawl spaces with limited height?
With a low crawl space, installing a Duofor floor is more difficult due to the manual work required on site, while Compofloor can be prefabricated without crawling.
What is the cost comparison between a Duofor floor and a Compofloor?
The material costs may be comparable, but the additional labor, finishing, and longer renovation time often make a Duofor floor more expensive in practice.
Can a Duofor floor be applied to a brick foundation without risk?
This depends on the condition of the masonry; Compofloor distributes the load better and is therefore safer to use on older masonry foundations.
What makes Compofloor more consistent in quality than Duofor?
Compofloor is factory-produced and tested, while the quality of a Duofor floor depends on manual installation and local implementation variations.
