1. What panel are you making?
Record the core material, metal facings, joint profile, dimensions and intended application. Identify the countries where the panel will be sold and the required performance evidence. BS EN 14509:2013 addresses factory-made, self-supporting, double-skin metal-faced insulating panels. Confirm the applicable standard and edition with your technical adviser; do not assume the same scope covers flexible-facing insulation boards.
2. Which production route fits the brief?
Fineagles’ published PU/PIR process includes facing preparation, preheating, metering and pouring, the double belt, cutting, cooling, stacking and wrapping. Its mineral-wool page describes board supply, cutting and turning, adhesive application and a laminating press. Use these different process routes to structure the discussion, then confirm the equipment included in your proposal.

3. How will output be measured?
State the required saleable output and product mix, not only a preferred line speed. Ask which panel thicknesses, widths, material system and operating conditions underpin each quoted figure. Agree how changeovers, planned stops and rejected material will be treated when comparing proposals.
4. What must the site provide?
Share the available floor plan, access routes, material-storage areas and utility information. List interfaces with existing equipment. Ask for a project-specific review of material handling, extraction, chemical storage and applicable local safety requirements. Keep responsibilities for foundations, utilities and installation explicit.
5. What will acceptance demonstrate?
Agree the trial materials, product sizes, measurement methods, run conditions and pass criteria before ordering. Separate equipment acceptance from the testing and documentation needed for finished-panel claims. Define operator training, maintenance information and spare-parts scope. A shared checklist makes proposals easier to compare and leaves fewer assumptions for commissioning.
