Design & Specification Notes
Composite structure with timber beams on steel columns for reduced embodied carbon and efficient spans.
Typical Uses
- •Primary frame
- •Long-span elements
- •Load-bearing supports
Key Performance
High load-bearing capacity for primary frame.
Specification Actions
- •Provide an EPD (EN 15804) or verified embodied carbon figure (A1–A3), and state the life-cycle stages covered.
- •Confirm timber elements are certified (FSC/PEFC)
- •Verify connection details allow for material separation at end-of-life
Indicative Health & Indoor Air
- •formaldehyde
Check adhesives and connections for emissions. Timber elements should meet E1 formaldehyde class.
