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 The St. Anthony, a Luxury Collection Hotel, San Antonio in San Antonio, west-facing windows at low afternoon sun angles drive the highest interior temperature increases. This is especially problematic for home office installations, which glare control and uv protection are critical for home offices with screen-facing windows.
High solar intensity, clear skies, and widespread adoption of energy-efficient building codes make this region one of the highest-risk markets for window-reflection turf burn.
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.
Perforated film is the most aggressive diffusion solution. The micro-hole pattern physically prevents any focused beam from forming. Best for large picture windows with severe reflection problems.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
