Will the touchfoil™ work through insulated glass types e.g. K-Glass?
No, the touchfoil™ operates through non-metallic or non-conductive glass only.
This type of glass (K-glass, Low-E) uses a metal in the manufacturing process so the touchfoil™ will not work through it. Other metal tints also stop the touchfoil™ from working.
For safety reasons, visualplanet recommend toughened and/or laminated glass.
Ask for any safety marks that are a legal requirement to be placed at the very edge of the glass.
