Most t&g or interlocking laminate panel floor finishes can be laid directly onto Isocheck Impact Mat 100 although a 3mm layer of plywood over the Mat would improve performance and stability. If in doubt please contact us with the floor specification.

Finished timber floors should be isolated from the skirting using Isocheck Acoustic Flanking Band.

Full installation instructions are available and must be used in conjunction when laying this floor system.
