Direct Answer (TL;DR)

Not when specified correctly. Modern solar control films in the recommended VLT ranges (40-60%) filter light, not block it. They remove the harsh, glaring component of sunlight while preserving a bright, pleasant ambient light. The space remains daylit without the negative side effects of glare.

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.
