Mushroom cultivation is climate control in a box: button mushrooms fruit at 16–18°C and 85–95% humidity, and a one-degree swing shows up in the flush. In tropical and Gulf climates, the envelope — not the chiller — decides whether that setpoint is affordable.
Why sandwich panels are the default for growing rooms
- Insulation: 100–150mm PU/PIR core keeps heat gain low enough that a modest chiller holds setpoint even at 45°C outside.
- Humidity: 90%+ RH condenses on any cold bridge. A continuous foam core with tongue-and-groove joints eliminates the through-metal bridges that drip onto beds.
- Washdown: rooms are sterilized between crops; aluminum faces tolerate chlorine-based disinfectants that corrode bare steel.
Roof vs. wall spec
Roofs take 150mm in hot climates; walls 100mm is common. If the growing rooms sit inside an existing shed, 100mm all around works because the outer building shades the panels. Compare core options in our PIR vs EPS vs XPS guide.
A note for Southeast Asian growers
Vietnam and the Philippines are the fastest-growing mushroom markets we quote. Panels ship from Tianjin with Form E documentation for ACFTA duty reduction — details in the Da Nang and Cebu supply pages.
FAQ
Q: Can you supply cold room doors too?
Yes — hinged and sliding insulated doors matched to panel thickness ship in the same container.
Q: Is PIR worth the upgrade over PU here?
If local fire code or insurance demands B1, yes; thermally they are close at these thicknesses.
Q: Smallest workable order?
A single 40ft container covers roughly 4–6 standard growing rooms including trims.
