FAQ

• Q1:

  How Do I Choose Between Laminated Smart Glass and Self-Adhesive Smart Film?

  

  A:

  Choose laminated smart glass when ordering new glass or when enclosing the film within the panel is important. Choose self-adhesive smart film when suitable glass is already installed and avoiding replacement is the priority. Confirm the environment, glass dimensions, wiring and total installed cost before ordering.

  
  

• Q2:

  Should I Use Laminated Smart Glass or Self-Adhesive Smart Film in a Bathroom?

  

  A:

  For glass frequently exposed to water or moisture, laminated smart glass is generally the better starting point, provided its edges and electrical connections are properly designed. Self-adhesive film should be considered only on a dry, protected surface that meets its installation requirements.

  
  

• Q3:

  What Is the Difference Between Laminated Smart Glass and Self-Adhesive Smart Film?

  

  A:

  Laminated smart glass is a finished glass panel with PDLC film enclosed inside the glass. Self-adhesive smart film is applied to the surface of existing glass. Both provide switchable clear and frosted states, but they differ in construction, installation and exposure of the film.

  
  

• Q4:

  When Should I Choose Laminated Smart Glass?

  

  A:

  Choose laminated smart glass when planning a new glass installation, replacing existing panels, or specifying glass for a demanding environment. It is also a good choice when the project needs the film enclosed within the glass and the wiring details planned during fabrication.

  
  

• Q5:

  How Do I Choose Between EP and EC Glass?

  

  A:

  Start with three questions: How quickly must the glass respond? What should it look like during a power outage? How much light and solar heat should it admit in each state? Compare product samples and tested data for the complete glazing assembly before making the final selection.

  
  

• Q6:

  Which Is Better for Skylights and Sun-Facing Windows?

  

  A:

  Both can be considered for skylights and windows. EP is appealing when fast tint changes are a priority. EC may suit projects where gradual tint transitions are acceptable. Compare the required glass sizes, clear- and dark-state appearance, controls and tested solar performance.

  
  

• Q7:

  Can Both EP and EC Glass Be Set to Intermediate Tint Levels?

  

  A:

  Yes. Both technologies can provide settings between their light and dark states when paired with suitable controls. The available range and how precisely each level can be maintained depend on the selected product.

  
  

• Q8:

  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.

  
  

• Q9:

  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.

  
  

  
  

• Q10:

  Why Is the VLT Change Smaller with Black PDLC?

  

  A:

  The added black window film provides a fixed tint in both electrical states. The PDLC layer can switch between frosted and clear, but the black tint remains, limiting the overall change in VLT.

  
  

• Q11:

  What Is the Main Difference Between Black PDLC and Black DLC Film?

  

  A:

  Black PDLC is made by applying black window film to both sides of white PDLC film. Black DLC uses dye liquid crystal technology to create its dark state. This difference in construction gives Black DLC a wider visible light transmission (VLT) range in InnoGlass’s product lineup.

  
  

• Q12:

  Which smart glass technology should I choose?

  

  A:

  As a simple guide: choose PDLC/PNLC for privacy, DLC for privacy plus shading, EP (SPD) for fast dynamic solar control, and Photochromic Glass for automatic power-free shading. The final choice should also consider glass location, sunlight intensity, desired transparency, privacy requirements, glass structure and project budget.
