3M Commercial Insulating Window Film

Technological advancements have increased the energy efficiency of windows since the days when single pane clear glass was the universally accepted building standard in the United States. No matter how efficient a window is on paper, is still an inefficient building material when compared to brick, concrete, plywood, and drywall installed with insulation.

Excessive heat transfer and heat loss create temperature imbalances that HVAC systems are designed to cure, albeit at a significant up-front and monthly cost. 3M commercial window film is a retrofit product that when properly installed can help reduce heat transfer and loss by decreasing a window’s Solar Heat Gain Coefficient (SHGC) and U Value, all without changing the appearance of the window!

So what does that mean to the commercial building owner, property manager, or facility engineer?

Allow single pane glass to approximate the U value of double pane glass

Earn up to 11 LEED points

Allow double pane glass to approximate the U value of triple pane glass

Improve Energy Star Portfolio Manager Score

Reduce utility bills by up to 10%

Help comply with local energy efficiency legislation

Reduce temperatures by up to 16°F

May be eligible for utility rebates

Window film is a fraction of the cost and headache of window replacement and almost as effective. Refer to the table below to see how 3M’s Thinsulate Climate Control 75 Window Film can reduce the U Value of a single pane window to almost that of double pane as well as offering a 35% improvement in reducing the sun’s total solar energy.

U Value Before U Value After Improvement SHGC Before SHGC After Improvement
Single Pane (1/4) 1.03 0.62 40% 0.82 0.53 35%
Double Pane(1/4, 1/2 air gap, 1/4) 0.47 0.35 26% 0.70 0.51 27%

Commercial decision-makers can realize significant cost savings by addressing inefficiencies of a building’s envelope. Typical window film payback is 3-7 years before any applicable utility rebates. Prescriptive rebates range from $1-$2 per square foot while custom incentives generally cover 40%-50% of a project’s cost.
