FAQ

• Q111:

  Does Darker EP Glass Provide Complete Privacy?

  

  A:

  A darker tint can make it harder to see through the glass, but it should not be specified as complete visual privacy without checking the selected product and lighting conditions. If dependable obscured-view privacy is essential, ask about a dedicated privacy film.

• Q112:

  How Is EP Film Different from PDLC Privacy Film?

  

  A:

  PDLC switches between a transparent view and a white frosted privacy state. EP changes how dark the glass appears while retaining its role as solar control glazing. The better choice depends on whether the project prioritizes frosted privacy or adjustable shading.

• Q113:

  Can EP Film Stop at a Tint Between Dark and Clear?

  

  A:

  Yes. EP film supports intermediate tint settings, so users can choose a light level that suits the time of day instead of switching only between two states.

• Q114:

  What Happens When EP Film Is Powered Off?

  

  A:

  The film returns to its dark state when power is off. When power is applied, it becomes lighter and allows more daylight through the glass.

• Q115:

  What Is EP Smart Film?

  

  A:

  EP smart film is InnoGlass’s adjustable solar control film similar to SPD technology. It lets users change the tint of their glazing to manage daylight, glare and visual comfort.

• Q116:

  How Do I Choose Between DLC, PDLC, PNLC and EP (SPD)?

  

  A:

  Choose PDLC for white frosted privacy when power is off, PNLC for a clear off-state, DLC for dark opaque privacy when power is off, or EP (SPD) when adjustable visible light transmission is the main requirement.

• Q117:

  Where Can DLC Smart Film and Glass Be Used?

  

  A:

  DLC can be considered for windows, doors, partitions, meeting rooms and residential glass where dark privacy and adjustable light transmission are useful. The installation method depends on the selected film or glass product.

• Q118:

  Does DLC Smart Film Need Power to Maintain Privacy?

  

  A:

  No. The film is dark and opaque when power is off. It requires power to switch to and maintain its clearer state.

• Q119:

  Is DLC Smart Film Suitable for Solar Control?

  

  A:

  DLC can provide electrically controlled shading. For projects with a specific solar heat reduction target, select the film and glass build-up using measured performance data.

• Q120:

  Can DLC Smart Film Reduce Sunlight and Glare?

  

  A:

  Yes. In its dark state, DLC absorbs more visible light, which can help reduce brightness and glare. The degree of shading depends on the selected product.
