FAQ

• Q71:

  What Is the Main Difference Between EP and EC Smart Glass?

  

  A:

  EP glass uses SPD technology to adjust light transmission by changing the alignment of suspended particles. EC glass uses an electrochromic coating that changes tint through an electrical reaction. Both can control daylight, but they differ in switching speed, power use and behavior when power is removed.

  
  

• Q72:

  How Do I Choose Between DLC and EP for My Project?

  

  A:

  First decide what must happen when the glass is darkest. Choose DLC when the glass needs to obscure the view as well as reduce light. Choose EP when the priority is to adjust tint and daylight. Then compare samples and the on/off VLT and solar performance data for the proposed glazing.

  
  

• Q73:

  Which Film Is Better for Windows and Skylights?

  

  A:

  EP suits windows and skylights where occupants want to adjust glare and daylight throughout the day. DLC suits glazing that also needs a dark opaque privacy state. The best option depends on the required off-state, desired view and glass construction.

  
  

• Q74:

  Which Film Is Better for Solar Shading?

  

  A:

  Both can reduce incoming visible light. EP is a good starting point when the main goal is adjustable shading while retaining a view. DLC is worth considering when dark privacy and shading are both required. For a specific solar heat reduction target, compare tested data for the complete glass assembly.

  
  

• Q75:

  Can Both DLC and EP Film Be Dimmed Gradually?

  

  A:

  Both can offer intermediate light levels with a suitable controller. Their visual effects differ: DLC moves between a dark privacy state and a clearer state, while EP varies the depth of its tint. Confirm the available dimming range for the selected model.

  
  

• Q76:

  Can People See Through DLC and EP Film in Their Dark States?

  

  A:

  DLC’s off-state is designed to obscure the view. EP’s dark state reduces visibility by limiting light, but what can be seen through the glass depends on the selected product and lighting on each side. If visual privacy is essential, test the proposed glazing under the project’s actual lighting conditions.

  
  

• Q77:

  What Happens When the Power Is Off?

  

  A:

  InnoGlass DLC becomes dark and opaque when power is off. EP returns to its dark tint. Although both reduce incoming light, a dark EP tint should not automatically be treated as equivalent to DLC’s opaque privacy state.

  
  

• Q78:

  What Is the Main Difference Between DLC and EP Smart Film?

  

  A:

  DLC (Dye Liquid Crystal) film combines a dark opaque privacy state with adjustable light control. EP film, based on SPD technology, primarily adjusts the tint of the glazing to manage daylight and glare. The key choice is whether the project needs obscured-view privacy or variable shading with a view through the glass.

  
  

• Q79:

  How Should I Choose Between Black PDLC and Black DLC?

  

  A:

  Decide how dark the glass should be when off and how bright it should be when on. Choose Black DLC if you need lower off-state VLT and higher on-state VLT. If Black PDLC’s narrower VLT range meets the project brief, compare samples of both products in the intended glass and lighting conditions before specifying one.

  
  

  
  

• Q80:

  Which Film Is Better for Adjustable Light Control?

  

  A:

  Black DLC is the stronger option when a project needs a larger difference between its dark and clear states. Black PDLC is more suitable when a consistently dark appearance is acceptable and the main requirement is switching the view between obscured and clearer.
