FAQ

• Q61:

  When Is Self-Adhesive Smart Film the Better Choice?

  

  A:

  Self-adhesive film is well suited to retrofitting suitable glass that is already installed. It can add switchable privacy without removing the glass, provided the surface is in good condition and there is a suitable route for wiring.

  
  

• Q62:

  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.

  
  

• Q63:

  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.

  
  

• Q64:

  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.

  
  

• Q65:

  Does Either Technology Guarantee Privacy?

  

  A:

  A dark tint can reduce visibility through glass, but neither EP nor EC should automatically be specified as complete visual privacy. Visibility depends on the product and the lighting on both sides of the glass. Test the proposed glazing if obscuring the view is a project requirement.

  
  

• Q66:

  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.

  
  

• Q67:

  Which Glass Needs Power to Stay Clear?

  

  A:

  EP glass needs power to maintain a lighter state. Many EC systems require energy mainly to change tint and can hold a selected state with little or no continuous power, depending on their design. Compare the complete system’s power specifications for the project’s expected operating pattern.

  
  

• Q68:

  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.

  
  

• Q69:

  What Happens When the Power Goes Off?

  

  A:

  InnoGlass EP glass returns to its dark state when power is removed. EC glass does not necessarily return immediately to a fixed state; its behavior depends on the electrochromic system. Check the specified product’s power-loss behavior before selecting either option.

  
  

• Q70:

  Which Glass Changes Tint Faster: EP or EC?

  

  A:

  EP glass typically changes tint much faster. It is useful where occupants want a prompt response to changing sunlight. EC glass generally changes more gradually, and its switching time can depend on the glass size and system design.
