Installation Weather Guidelines - Car Window Film

The main concern with installing film at temperatures below freezing would be that any water left behind during installation would freeze and cause a visible defect in the film. Thus the best method for reducing any potential problems would be to take extra care to remove all excess water during installation. The only way that the water could potentially freeze would be if the temperature of the interior pane of glass dropped below 32 ̊F. Below are a few recommendations to look for when installing in cold temperatures.

As a general rule these guidelines would be recommended any time temperatures are expected to be under 10 ̊F for double pane glass or under 40 ̊F for single pane glass, within 72 hours of the installation period.

  1. Check the temperature of the interior pane of glass, with an understanding that the temperature of the glass will drop significantly at night. If the temperature of the interior pane is less than 40 ̊F do not install film.
  2. Spray the glass with film mounting solution if the mounting solution freezes do not install film.
  3. Use a temperature gun to determine the temperature of the frame of the window right next to the glass. Water left around the edges of the glass could freeze due to the frame
  4. Check to see if heating vents are directed at the glass and will hold that glass at a warmer temperature, often allowing film installation at significantly lower outside temperatures.
  5. Determine what temperature the building is kept at during the night. Often unoccupied spaces, or spaces being renovated will be kept at much lower temperature, as are some buildings that utilize temperature setbacks at night.

In general, there are very few days that would prohibit film installation in the US climate. The interior temperature of the building will typically hold the interior glass temperature above 32 ̊F. The above are situations to be aware of, as well as suggestions to minimize the risk of installing film in temperatures that are too low.

DISCLAIMER: When applying film on cars, always check with your local authorities on restrictions for your application in your area. This product is to be installed by an experienced, professional car window film installer. Installation should not commence if glass temperature drops below 40 degrees Fahrenheit or 5 degrees Celsius.
