We do not perforate these Decoraids tiles but looking into it. We are sending these for testing soon without perforation to see what the NRC value is. We have used these tiles in many commercial spaces, even breweries and no-one has mentioned echo issues.
We are currently not too far away from launching perforation for MirroFlex ceiling tiles.
The tiles that can be perforated at this time are our metal tiles. We offer this for Tin Plated Steel, Aluminumand Solid Copper. We charge 12 dollars for perforating of a 2′×2′ tile on top of the price of the tile.
Our Aluminum tiles come in 72 colors and so there is a nice selection of designs and colors.
