Why This Matters
The concave bow in double-pane glass is typically only 1–3mm of deflection. That's enough to create a focal point 10–30 feet from the window — right where most residential turf installations sit.
Near REI in Boulder, energy-efficient double-pane glass with low-e coatings can be enhanced further with retrofit film. This is especially problematic for historic or older home installations, which older single-pane windows benefit most from low-e retrofit film to improve thermal efficiency.
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
The fix is straightforward: apply a window film that diffuses or absorbs the focused energy before it reaches your turf.
Low-e retrofit film is specifically designed to address the low-e glass reflection problem. It modifies the reflective properties of existing glass without replacement — the most cost-effective solution for new construction.
Reduces glare and diffuses focused solar energy to protect interiors and improve comfort.
