Before purchasing your touch foil, it is always a good idea to test your glass surface for conductive coatings with our low-e glass tester. Applied touch products almost always use capacitive sensors to track input. Conductive coatings (such as a low-e coating) can cause interference with your touch foil’s sensors. This results in the touch foil mistaking the interference for user input. If the level of interference is too great, it becomes practically unusable.
Using one of our low-e glass testers can save you a lot of trouble. If you know your glass is compatible, you can take the next step and purchase your very own interactive touch foil.
