First vs Second Surface in Window Graphics: What’s the Difference?

When installing window graphics, you can apply them in two ways — first surface or second surface.

The choice affects both appearance and durability.

 

First Surface (Outside Application)

Graphics are applied on the exterior side of the glass with adhesive on the back.
Pros:

  • Maximum visual impact with no glass glare
  • Direct exposure for vibrant colors

Cons:

  • Exposed to weather and potential damage
  • May be subject to zoning sign restrictions

Second Surface (Inside Application)

Graphics are applied on the interior side of the glass facing outward, with adhesive on the front.
Pros:

  • Protected from weather and vandalism
  • Typically exempt from exterior sign regulations

Cons:

  • Slightly reduced clarity due to glass reflection

Modern Solutions

Advances in printable films make second-surface installs more effective.
By printing mirror artwork (reverse printing) on clear films (like Graphictac Optically Clear removable), graphics appear crisp from the outside while staying protected indoors.

 

Choosing the Right Method

Select the method based on the installation environment, desired visibility, and durability needs, to ensure the application achieves both visual appeal and long-term performance.
