Building Physics & Export Logistics

Fire Resistance & Acoustic Performance: Certified multi-layer dry construction wall buildups up to REI 120
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: Vertically stacked in specialized shipping stillages for crane unloading
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

2D pre-panelized wall and floor cassettes (dimensions up to 3.8m high x 12.0m long) are pre-assembled on precision automated framing tables in our facility. Studs, lintels, and double top tracks are factory-screwed with robotic consistency, delivering exceptional load transfer symmetry and eliminating on-site stud alignment errors.

2. Lateral Wind & Seismic Ductility

Factory-installed structural sheathing (magnesium oxide, fiber cement, or structural OSB) creates pre-certified structural shear diaphragms, delivering up to 3x higher racking resistance than field-installed boards.

3. Thermal Break & Moisture Control

Cavity insulation, external vapor-permeable weather barriers, and acoustic decoupling strips are pre-fitted under factory conditions, eliminating weather delays and guaranteeing Blower-Door airtightness (n50 < 0.60 h⁻¹).
