PERIMATE DI
| PERIMATE DI Insulation is designed for use on exterior basement walls because it has a unique drainage system: vertical channels cut in the face of the board drain water away, while a thin layer of filter fabric bonded to the surface prevents soil particles from blocking the channels. |
