Are you ready for the next Petaluma heatwave? Let’s face it: summer heat doesn’t affect every office the same way. Buildings in the North Bay with large areas of glass often experience higher indoor temperatures. What about persistent glare and uneven cooling? That’s another challenge for offices in Sonoma and Napa County. For many businesses, the windows—not the HVAC system—are the primary source of the problem.
That was the case for this Petaluma office. The owners wanted to reduce solar heat without sacrificing the natural daylight that defines the workspace. ClimatePro installed 3M Prestige Window Film throughout the building, creating a more comfortable environment while preserving the clear appearance of the existing glass. The result is an office that’s better prepared for the next heatwave without replacing a single window.

Large Windows + Large Heat Sources: Higher Temperatures
Modern offices are designed to maximize daylight, but untreated glass also allows solar energy to enter the building throughout the day. As interior surfaces absorb that energy, temperatures rise near the windows, and the cooling system works harder to maintain a consistent indoor climate.
The symptoms are familiar. Employees close the blinds, workstations near the glass become less desirable, and conference rooms warm noticeably during afternoon meetings. Lowering the thermostat rarely solves the underlying issue because it doesn’t reduce the amount of solar heat entering through the windows.

Security, Comfort & Peace of Mind

Why 3M Prestige 70 Was the Right Choice
This project required a film that would reduce heat without altering the building’s appearance. The owners wanted to maintain bright workspaces and unobstructed views, making heavily tinted or reflective films a poor fit. 3M Prestige 70 meets those requirements by rejecting a significant amount of solar heat while remaining remarkably clear. It also blocks 99 percent of UV rays and reduces glare, allowing employees to enjoy natural light without the discomfort that often accompanies it.
ClimatePro recommends 3M Prestige 70 for offices that need meaningful heat reduction while preserving daylight and the glass’s original appearance. Give us a call for a free consultation today: 707.755.7337 or get started online here.
