The 60 mm panel with mineral wool is available in selected wall families. However, it should not be treated as a solution for every small building. Insulation performance, load-bearing capacity and fire requirements must be checked. The 40 mm offer may relate to a different core. Before comparing prices, it is worth confirming which product is actually being sold. No. The thickness range depends on the panel family. In some catalogues, wall panels with mineral wool start at 60 mm, in others at 80 mm or more. A single availability table for the whole market should not be created. The dimension must be confirmed for the specific product, joint and facings.

Panels with mineral wool are often considered where fire requirements matter. Their use does not, however, end with a large hall. They can also form the walls of back-of-house areas or a small service building. Suitability is determined by the verified wall assembly, not by the mere presence of mineral wool in the core. It is worth taking openings and joints into account from the outset. Ready-made panels with mineral wool can have a favourable reaction-to-fire class. An example is A2-s1,d0 for a specific product. However, this does not automatically mean any given wall resistance. The latter property relates to the behaviour of the complete wall assembly during testing and is described by separate criteria.

Similar thickness and white colour do not mean that two panels with mineral wool are interchangeable. The core density, the sheet thickness and the fixing method may differ. In a small pavilion, these features affect transport, wall performance and cost. It is worth starting the comparison with a single technical table and only then moving on to price. Terms suggesting a basic or reinforced version are offer names. They do not form a common scale for the whole market. One variant may have a lighter core, another different facings or concealed fixing. Without data, it is difficult to tell what change lies behind the name and whether it is needed in a given building.

A thicker core can improve the thermal insulation of a mineral wool panel. However, it does not automatically mean the highest fire class or the best solution for every building. With 150 and 200 mm, weight, fixings and details must also be checked. The choice makes sense when the greater thickness helps achieve a specific project goal. In one family of mineral wool wall panels, the 150 mm variant has a Uc of 0.27 W/(m²·K), and the 200 mm variant 0.20. Both have 0.5/0.5 mm facings and a defined core construction. These are data for this family, not values for all panels of these thicknesses. Before comparing, the conformity of the variants must be confirmed.

The 60–200 mm range offers several options, but it does not form a simple ladder from worse to better material. Thickness must be linked to temperature, fire requirements and construction. A thinner panel may suffice in one application, while a thicker one may be needed in another. First define the wall's task, then compare full variants. Determine whether the building will be heated continuously, periodically or not at all. Describe the humidity and the type of work inside. Check the fire and acoustic requirements. This requires panel spans, installation direction and an opening plan. None of this information is replaced by the floor area alone.

An outlet panel can lower the cost of a small enclosure, but a discount alone does not yet tell you whether the material suits the job. First you need to know why the grade was reduced. A scratch on the coating is a different problem from a damp core or a crushed interlock. It is also worth calculating how much of the purchased batch can be used without weakening the required wall properties. There is no single common list of defects for all outlet offers. The material may come from the end of a production run, a dimensional surplus or a batch with a visual deviation. It may also be damaged. The description should clearly distinguish these situations. The term “second grade” on its own specifies neither suitability nor the scope of documentation.

The weight of a panel with a mineral wool core is needed to check the structure, delivery and lifting method. It is not worth guessing it from thickness alone. The core, steel facings and module width matter. It is particularly easy to confuse kilograms per linear metre with kilograms per square metre. The examples below show how to calculate correctly. The weight consists of the mineral wool, both facings and the other components of the panel. Cores can have different densities. Steel sheets may be made in different thicknesses. Profiling changes the amount of material per covered area. Therefore the name “100 mm panel” does not define a single weight.
