Frequently Asked Questions

Please note that various types of foam will affect your keyboard differently depending on your keyboard's case, plate, etc.

EVA is a closed-cell foam, whereas PORON is an open-cell foam. This means that PORON performs better at absorbing and reducing sound than EVA due to its permeability. The structure of open-cell foam allows for sound waves to interact with residual membranes and transform the energy to heat – reducing the sound.

Our foam is pre-cut to allow for greater ease in fitting with your specific keyboard size. Please note that our foam can also be manually cut to fit different sizes, if the provided sizes do not work for you.

This foam is installed below your PCB, in between the PCB and the bottom case. Our foam will compress a bit and will fit most keyboards – however, compatibility is dependent on the bottom case clearance of your keyboard.
