This $5 Window Hack Cuts Your Cooling Bill by 30%. Why Is the HVAC Industry Scared?

This hack uses the trapped air in bubble wrap to stop "thermal bridging" through window glass. It provides instant insulation while still letting in natural light. The HVAC and Glass Industries bury this because it is too cheap to monetize. They prefer to sell "reflective window films" that cost 20x more but often provide less thermal resistance. In many high-end rental markets and "managed" apartment complexes, this is "illegal" under Lease Appearance Clauses, which prioritize building "prestige" over the tenant's ability to stay cool for pennies.
