[Substrate] What thickness of material can the touchfoil™ work through

The touchfoil™ can be programmed for different thicknesses of glass and even used with gloved hands. Standard configuration functions with non-metallic, non-conductive single construction glass which caters for up to 20mm inclusive of glass and air gap.

Double glazing is also possible, however in this mode visualplanet recommend only touch and not the touch and drag function. The drag functionality is limited due to the reduction of the scan rate to achieve the touch through thicker materials.


When fixing to double glazing please note that 1mm of air is equal to 3mm of glass.

4mm glass + 10mm air + 4mm glass
= 4 + (10x3) + 4 = 38mm of glass

Please bear this in mind when testing double glazing with the visualplanet touchfoil™.


Due to the variation in double construction glass visualplanet recommend testing with a touchfoil™ during the survey of each individual site since it is impossible to guarantee the touchfoil™ will function in all cases.

Please contact the visualplanet support team to discuss further.
