Universal Z-Z channel for mounting wall panels to existing wall

A method of mounting insulation panels unto an existing wall comprising the steps of, installing at least two Z-shaped components onto an existing wall, said at least two Z-shaped components being in a spaced apart configuration with each other;

• either one of said at least two Z-shaped components having at least one row of plurality of coaxial retaining slots;
• inserting at least one insulation panel between said at least two Z-shaped components, wherein said at least one insulation panel being locked into place between a second wall of said one of the at least two Z-shaped components and beneath the rearwardly extending wall of another of said at least two Z-shaped components;
• securing said at least one insulation panel so as not to block at least one of said plurality of said coaxial retaining slots;
• and configuring air circulation by having air gaps within Z-shaped components;
• and installing wall panels onto the Z-shaped components.

A clip member comprising, at least one first portion and at least one second portion in a co-linear orientation, said first and said second portions each having a first side and a second side, said at least one first portion configured for insertion into a retaining slot of a Z-shaped component;

• wherein said second portion having at least one protruding wall protruding perpendicularly from said first side;
• wherein either said second side of said second portion or said at least one protruding wall configured to abut against a top surface of an insulation panel;
• wherein said at least one protruding wall configured to secure said insulation panel in place or to prevent over insertion of said first portion into said retaining slot;
• and wherein said insulation panel being insertable between one of said Z-shaped component and another of said Z-shaped components that is in parallel spaced apart orientation with said one of said Z-shaped components.
