Santiago in Vietnam makes 4-layer ASA/PVC roofing sheets (ASA top layer, three PVC layers, 100% virgin resin). In Myanmar's long monsoon they keep rain noise about 80% lower than metal and do not rust at screw holes (Santiago measurements). Tile-look sheets suit homes, monasteries and schools; 5-wave sheets suit farms and warehouses. Minimum order is one 40 ft container, about 5,000 m, with Form D for ASEAN tariff preference.

1. Why does the monsoon matter for roof choice?
From about May to October the south-west monsoon brings long spells of heavy rain, most of all on the Rakhine and Tanintharyi coasts and in the delta. On a metal roof that rain is loud enough to stop a class or a prayer, and water standing around screws rusts the sheet from the holes outward. An ASA/PVC sheet damps the drumming and has nothing to rust.
2. Which profile for which building?
| Building | Profile | Why |
|---|---|---|
| Houses, monasteries, schools | Spanish tile, 1.05 m wide (0.96 m cover) | Looks like clay tile, quiet, light on old timber |
| Farms, rice mills, warehouses | 5-wave, 1.08 m (1.00 m cover) | Long spans, fast to fix |
| Workshops with chemicals | 6-wave, 1.06 m (0.95 m cover) | Stiffer rib, resists fumes |
