Why Sustainable Framing Starts with Steel
In North America, more than 30 million trees are harvested every year solely for wood framing in residential construction. While forests can regrow, the carbon impact of logging, processing, and transporting lumber is irreversible within any single project’s lifespan.
At LEFF, we believe homes should not cost the planet. That’s why we design with cold-formed steel (CFS) — a structural material that requires zero deforestation and offers measurable environmental advantages:
✅ Up to 85% Recyclable Content: Most CFS components are produced from recycled steel and can be recycled again at end-of-life without degradation of quality.
✅ Lower Embodied Carbon: Compared to wood, CFS framing systems contribute significantly less to deforestation-related emissions and land-use change.
✅ Longer Lifecycle: A steel-framed home often lasts decades longer than a wood-framed equivalent, reducing the need for demolition and rebuild cycles.
It’s not just about being “green” for marketing’s sake. It’s about building responsibly in an industry that affects both lives and landscapes.
