Adjustable block for a continuous panel manufacturing line and method of manufacturing insulated panels

An adjustable block configured to be used in a continuous insulated panel manufacturing apparatus, the adjustable block comprising:

• a first block portion with one or more first edge projections;
• a second block portion with one or more second edge projections;
• and
• a biasing assembly configured to allow at least one of the first block portion or second block portion to move with respect to the other to adjust the distance between the one or more first edge projections and the one or more second edge projections;
• wherein the adjustable block is configured to form a portion of a proximal edge or a distal edge of an insulated panel and define a thickness of the insulated panel.

A method of forming one or more insulated panels, the method comprising:

• distributing unexpanded insulation material between a first substrate and a second substrate that expands between the first substrate and the second substrate;
• heating the first substrate, the second substrate, and expanded insulation material therebetween;
• and
• adjusting a plurality of adjustable blocks to form the insulated panel with a thickness based on an adjustment of the plurality of adjustable blocks.
