Temperature-Controlled Warehouse Construction Using EPS Isowall Sandwich Panels

Temperature-Controlled Warehouse 40 x 48 x 9 m
Prefabricated Structural System + Sandwich Panel EPS (Isowall) Wall & Roof System
For pharmaceutical storage and temperature-sensitive goods – Phutthamonthon Sai 5, Nakhon Pathom

This HW-HC warehouse (40 x 48 x 9 meters) provides a total usable space of 1,920 sq.m. Designed specifically for the storage of medicine, medical supplies, and temperature-controlled products, the structure utilizes a prefabricated steel system combined with EPS Sandwich Panel roofing and walling, which significantly reduces heat transfer and speeds up installation time.
The foundation system uses Precast footing with closely spaced driven piles, designed to support 1 ton/sq.m., ensuring stability, load-bearing performance, and minimal long-term settlement.
