The bi-fold door has several sustainable/green features:
1. All of the wood used by Weather Shield is sourced from managed forests. FSC-certified wood can be specified.
2. Zo-e-shield glazing packages deliver energy efficiency and protection from UV rays. Packages available on the bi-fold door include Zo-e-shield 5 (with two panes of glass, one argon-gas-filled airspace, a warm-edge spacer and multiple layers of Low-E coating), Zo-e-shield 5 Extreme (with an additional Extreme coating layered atop the Low-E coating applied to Zo-e-shield 5 glazing), Zo-e-shield 6, with a third pane of glass and laminated interlayer; and Zo-e-shield 7 (three panes of glass, two gas-filled airspaces, multiple layers of Low-E coating and a warm-edge spacer).
3. Low/no-VOC and HAP paints and finishes.
Varies by size and specifications.
The bi-fold door features a zero-threshold sill, which makes the door practical for ADA-compliant uses.
