Do window films cause seal failure when applied to double pane/insulate glass?

Window films, when properly selected and installed, do not inherently cause seal failure in double pane or insulated glass units (IGUs). However, there are considerations to be aware of:

  1. Heat Absorption: Some window films, especially darker or highly reflective ones, can increase heat absorption. This can lead to a temperature differential between the center and edges of the glass, potentially stressing the seals of IGUs. It’s essential to choose films designed for double pane windows to mitigate this risk.
  2. Existing Seal Conditions: If the seals of an IGU are already compromised or nearing the end of their lifespan, any additional stress, even from window film, might expedite seal failure. It’s crucial to assess the condition of the seals before film installation.
  3. Manufacturer Warranty: Some window manufacturers might void the warranty of their IGUs if window film is applied. It’s always a good idea to check with the window manufacturer before proceeding.
