What does a finished mineral wool panel wall actually cost?

Keep net and VAT-inclusive figures separate. Does delivery mean arrival at the site or unloading as well? Give all suppliers the same scope. An omitted item is not a saving if it must be ordered separately later.

Check how long the quotation is valid and when the price becomes firm. A change in quantity or specification may require a new quotation. For a small order, minimum logistics charges matter. Halving the quantity does not necessarily halve transport and production setup costs.

Match core, both facing thicknesses, coatings, profile and fixing method. Any of these can change the price at the same panel thickness. Check fire performance and load capacity in the proposed arrangement. A cheaper panel is an alternative only if it meets the same project requirements.

A single price for an unspecified category is misleading. Run length, colour and lead time can affect the quotation. Use a stated allowance for preliminary planning and replace it before purchase with a quotation for the actual schedule of components.

Suppose the walls require 252 m² of finished cladding. After setting out openings and module widths, the order comes to 264 m². The extra 12 m² reflects the chosen layout and allowance in this example, not a standard waste factor for every building.

Check whether offcuts can be used above openings or in shorter bays before approving lengths. Keep the specified bearing and joint details. Saving material does not justify piecing panels together where neither the frame nor the system provides for a joint.

Using the store conversion rate on 12 November 2026, the illustrative panel allowance is about €35.69/m² net. The 264 m² order comes to €9,420.95 net, calculated before rounding the unit rate. Allow €894.45 for flashings and seals, €213.19 for fixings, €509.79 for transport and unloading, and €602.48 for equipment hire.

Installation is estimated at about €13.44 net per finished square metre. For 252 m² the unrounded calculation gives €3,386.87. The total is €15,027.73 net, or about €59.63 net per finished square metre. Assuming 23% VAT solely for this example gives €18,484.10 gross. The budget excludes the frame, windows, doors and foundations.

Many openings take time to trim even when the panel area is small. Wall height, difficult access and installation during ongoing operations can extend equipment hire. Delivery sequence matters too: a second trip for missing flashings can cost disproportionately more than the parts.

Test the sensitivity of the estimate. A net change of roughly €2.32/m² in the panel price changes this order by €611.75 using the unrounded rate. When comparing an upgrade, also check whether it needs different fixings or wider flashings. The panel surcharge need not be the whole difference.

Attach the length schedule and accepted panel specification to the order. Define flashings, fastener type and responsibility for measurements. Record delivery and unloading conditions so the final invoice can be checked against the scope originally compared.

Show any contingency separately with its purpose, such as unknown existing frame conditions or extra work around openings. Do not hide it in the material rate. A transparent estimate shows which item changed and how much each change costs.
