Building Physics & Export Logistics

Fire Resistance & Acoustic Performance: Non-combustible Euroclass A1 roof structure
Thermal Performance & U-Values: U-values from 0.22 down to 0.11 W/m²K engineered with continuous external insulation and thermal break isolators (GEG / RE2020 / Passivhaus).
Export Delivery & Container Packing: Assembled triangular trusses or flat-pack knocked-down truss kits
Serviceability Deflection Limits (SLS): Strict deflection limits from L/300 to L/500 preventing cracks in architectural cladding and interior drywalls.

Structural Mechanics, Load Paths & Finite Element Modeling

How vertical gravity, lateral wind, and seismic forces are dissipated through our engineered framing.

1. Vertical Gravity Load Transfer

Roof snow loads and solar PV arrays are supported by triangulated cold-formed steel pitched, mono-pitch, or mansard trusses spanning up to 18 meters clear. Top chords carry compression and bending, while bottom chords act in pure tension with high-strength screw-fastened gusset joints.

2. Lateral Wind & Seismic Ductility

Gale-force wind uplift and lateral gusts are resisted through continuous longitudinal ridge bracings, diagonal bottom-chord ties, and heavy hurricane-rated hold-down clips securing truss heels to perimeter wall studs.

3. Thermal Break & Moisture Control

Non-combustible Euroclass A1 galvanized steel prevents attic fire spread. Cold roof and warm roof configurations with continuous vapor-permeable roofing underlay membranes guarantee zero condensation under metal standing seam or tile cladding.
