While the upfront cost per square meter might be slightly higher than basic PU panels, a lifecycle cost analysis invariably favors high-performance PET panels. The long-term value comes from: radically reduced operational energy costs due to superior and persistent thermal performance; near-zero maintenance and no replacement costs for 50+ years; faster, lighter-weight installation that cuts labor and structural steel expenses; and a high end-of-life material residual value. Typically, the initial cost premium is fully recovered through energy and maintenance savings within a 3-5 year payback period.
