Timber Joisted Floors
Systems designed for suspended timber floors and upper levels, fitted between or across the joists.
Compare the three approaches
| Comparison criteria | In Screed | Overlay | Timber Joisted |
|---|---|---|---|
| Starting point | New concrete slab or structural screed | Existing solid floor, screed or timber deck | Suspended timber floor or upper level |
| System position | Embedded within the screed | Over the existing floor, beneath the finish | Between or across the timber joists |
| Main priority | Build in once for long-term efficiency | Low build-up and minimal disruption | A lightweight solution that respects the structure |
