Why This Matters
The reflective coating on low-e glass is invisible to the naked eye. Most homeowners don't know their windows have it — which is why the burn pattern seems mysterious until someone explains the optics.
Near Techne Instruments in Berkeley, energy-efficient double-pane glass with low-e coatings can be enhanced further with retrofit film. This is especially problematic for home office installations, which glare control and uv protection are critical for home offices with screen-facing windows.
The marine layer that covers coastal areas in the morning burns off by midday, leaving afternoons with intense, direct sunlight. This pattern creates a predictable daily window for reflection damage — typically 1pm to 5pm.
The Solution
Solar control films work on the absorption principle: they capture solar energy in the film itself, converting it to heat that dissipates into the glass rather than reflecting outward. Effective, durable, and widely available.
Hybrid films combine ceramic particles with metallic layers for maximum heat rejection. They're the right choice for extreme climates or windows with very high solar exposure.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
