Understanding heat reduction window film

Your guide to how solar control film works.

Overheating occurs when solar energy passes through untreated glass, steadily increasing the internal temperature. Window film will slow down this process.

  • Window film is available in a range of grades and finishes, with films available for internal and external installation.
  • Window film will reflect away a percentage of solar energy from the glass.
  • Window film will absorb excess heat before it can pass through the glass.
  • By preventing solar energy from passing through the glass (levels depend on the film chosen), window film will reduce excess heat build up.
  • Solar control film will also reduce glare by filtering out the harshest light.
  • Heat reduction window film will also block up to 99% of UV rays, helping to protect against fade damage.
