Installation & Structural Integration Protocol
Sequential handling logic, fastening tolerances, and joint sealing guidelines engineered for high-precision deployment of Phyto-board within heavy timber and light-gauge steel assemblies.
Verify framing moisture content is below 15% prior to board placement. Confirm true plumb plane across vertical studs.
Apply continuous adhesive bead into female profile before driving the male profile flush with mechanical dead-blow hammer.
Seat screw heads exactly 0.5mm below outer fiber plane without rupturing the exterior structural densification layer.
Roll all joint tapes with 50N downward pressure to ensure complete mechanical bond across cellular hemp substrate.
Quality Control & Continuous On-Site Verification
Each shipment includes standardized moisture witness tags and torque calibration blocks for immediate mechanical compliance testing.
