What Affects the Integrity of a Window Film’s Waterproof?

As with all things, there are some disclaimers to be made. While window films are waterproof, there are instances where your films could become compromised. Here are some circumstances that would affect the integrity of a window film’s waterproof properties.

  • Proper cleaning techniques. Window films generally have guidelines on how to properly clean them after they are installed. First, there is a curing period which needs to be honored before cleaning. Then, it’s important the films aren’t cleaned with any harsh chemicals or power washers as this can affect their adhesiveness and ultimately waterproofing.
  • Expected lifespan of window films. Window films aren’t engineered to last forever—that’s not to say they won’t easily live past 10 or 20 years. As your film ages, it may lose adhesion leading to loss of waterproof properties. Quality of materials and installation affect this lifespan. Therefore, it’s best to partner with a certified Rockville, MD commercial window tinting company to avoid any issue.
  • Quality of window film installed. Different brands of window films are engineered differently. Some films are created to meet a certain price-point and skimp on quality which can lead to sub-par waterproof ability. Consult with a local window tint company to see what type of brands they carry and to get their input on the best films for your situation.
