Why do manufacturers use IRR if it's misleading?
IRR numbers are easier to inflate by measuring specific, narrow wavelengths. It makes clear or light-tinted films look much more powerful than they actually are in real-world conditions.
Technical Context & Implementation
For large-scale commercial facilities, the implementation of this solution requires a systematic approach. Facility managers must consider the building envelope as a single thermal unit. When addressing why do manufacturers use irr if it's misleading, our verified installation partners utilize manufacturer-grade software to perform dynamic simulations.
This ensures that any retrofit—whether it be solar control, security laminate, or decorative privacy film—meets local building codes and maintains the structural integrity of the existing glazing system.
