Product Introduction
Moderate 75mm thickness balances thermal insulation while keeping self-weight low, reducing steel-structure cost and supporting easier manual lifting. Hidden tongue-and-groove joints interlock tightly for better weather protection; the flat, low-moisture surface resists warping and helps lower cooling energy use in South American summers.
