How do you go from choosing a mineral wool panel to a finished wall?

The structure must provide the required spacing and width of supports. The selection is made for a specific variant and loads. An example 100 mm panel may have Uc 0.39 W/(m²K) and a mass of 18.1 kg/m², but these figures do not on their own determine the permissible span. The relevant tables and installation conditions are required.

For staged construction, the design should show the completion of the part being built now and the method of future connection. The temporary section must perform for the duration of the break. Unprotected ends should not be left simply because extension is planned.

List the walls by specific lengths and number of pieces. Use the cover width. Mark openings and the cutting plan. The volume or area of the whole building does not replace this schedule. Panels made to length should follow from the confirmed geometry of the structure.

Include the specification of facings, coating and fastening. List flashings, seals and fasteners separately. If fire requirements are specified, the order must indicate a compliant solution. A part of the set must not later be replaced with a random product simply because it looks similar.

Also establish the scope of delivery and unloading. The seller needs information about access and the storage location. The installer should know the order of the packs. This helps limit the rehandling of heavy elements on site.

Check the plane of the structure, the supports and the anti-corrosion protection. Agree how deviations are to be resolved. The panel should not be used to straighten the frame by over-tightening the screws. Openings and structures for joinery should be ready in accordance with the agreed plan.

On delivery, compare lengths and markings with the order. Inspect the facings, ends and connections. A damaged edge can make the airtight assembly of the wall difficult. Discrepancies are documented before cutting begins. Later it is harder to distinguish a delivery defect from installation damage.

Packs must be properly supported and protected from water. If works are delayed, storage should be adjusted to the actual timeframe. Transport packaging is not indefinite protection on an open site.

The first section should be treated as a check of the agreed details. Direction, position, fixing pressure and seals are verified. A mistake noticed at the first panels is easier to correct than the same problem repeated across the whole façade. Compliance with the documentation matters, not just a straight outer line.

Cutting should be carried out using the method permitted for the panel. Swarf is removed as work proceeds. Connections at windows and the plinth should be inspected before being covered by flashings. Photographs of these locations help at acceptance but do not replace checking the materials used.

If an unforeseen opening or installation arises, a new solution must be established. The panel should not be cut first and support queried afterwards. The change may affect load-bearing capacity, tightness and the required fire function.

The finished wall has a complete set of connections, flashings and agreed penetrations. The surface is cleaned of swarf and packaging residues. Coating damage and the method of its repair must be checked. Acceptance should also cover access for inspections and the patency of the intended drainage.

The documentation covers the material used, the fixings and the approved changes. It is worth keeping the final panel layout drawing. For later repair, this will make it easier to find the correct element. The name ‘mineral wool panel’ alone will not be enough after a few years to reproduce the connection.

If the building starts being used before the entire project is completed, the enclosure must be protected during subsequent works. Equipment impacts, mortar and accidental fixings can damage the new wall. The organisation of the next stage should take into account what has already been correctly executed.
