Modern e-commerce logistics centers and cold chain hubs cover massive roof deck footprints. Passive insulation is critical to control indoor temperatures and prevent atmospheric condensation under metal roofing panels.
1. Condensation & Vapour Barriers (FSK/ALG)
When warm, humid air inside a warehouse rises to touch the cool metal deck, condensation forms. This moisture can drip onto inventories and trigger purlin corrosion. Wrapping building rolls in aluminum foil (ALG or FSK) provides a tested vapour transmission barrier, keeping the core dry.
2. High-Tensile Structural Roll Spans
Logistics hubs are built with broad purlin spacing. Specifying high-tensile mineral building rolls prevents sag or tears during manual laying across vast spans. The fibers must remain stable under seasonal wind and rain cycles to maintain insulation rating consistency.
