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%
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%|
