What should you know about 100 mm mineral-wool wall panels?

Consider a 100 mm panel with mineral wool of density 100 kg/m³, U = 0.39 W/(m²K) and mass 18.1 kg/m² with 0.5/0.5 mm facings. This variant permits vertical or horizontal installation on a suitable frame. These figures describe one example, not every wall panel of this thickness.

The order still needs width, lengths, coatings and profiling. Example coverage modules are 1000, 1050 or 1130 mm, subject to product availability. Module width changes the wall layout and cuts around openings and corners. Check the layout before comparing prices per square metre.

A 1000 mm module and 6000 mm length cover 6 m². At 18.1 kg/m², the panel weighs an estimated 108.6 kg. This calculation applies to the stated data. Calling it “light compared with masonry” does not plan handling: the crew needs the actual element lengths, weights and lifting method before delivery.

A second 100 mm panel example has U = 0.37 W/(m²K) and mass 17.0 kg/m² with 0.5/0.5 mm facings. Its core combines two wool densities and its coverage module is 1150 mm. Equal thickness conceals a different construction. These figures do not apply to every panel with a similar core.

These examples demonstrate comparison, not an order-ready specification. Verify the selected product’s own data and version. Changes to facings, joints or core may alter performance. A similar name is insufficient for repeat orders: confirm compatibility with elements already installed.

That depends on the wall’s required performance and building use. 100 mm is not a universal choice for a heated hall. Establish the design target and assess the whole wall, including junctions with foundations, roof, doors and windows.

If the required U-value is lower than the panel’s declared value, consider a thicker version or another solution. Changing colour or using a stronger screw cannot improve this. Meeting the target in the panel field also does not end the calculation: details and thermal bridges matter. Manufacturer data are inputs, not approval of the whole building.

An example mineral-wool panel may have reaction-to-fire class A2-s1,d0; confirm it for the ordered product. This is not the completed wall’s EI class. Fire resistance depends on orientation, supports and connections. Resolve conflicting documents by clarifying the applicable scope; thickness alone cannot settle it.

Selected panel variants may have Rw values of 33 dB or 27 dB. These are examples, not a range applying to all 100 mm panels. They cannot guarantee quiet without considering doors and other sound paths. Rw also does not describe sound absorption or room reverberation time.

State the panel variant, both facings, coating, colour and length schedule, plus accessories and delivery. A rate for a “100 mm panel” cannot establish the whole-wall cost. Confirm quotation validity and VAT basis, with extra costs visible before ordering.

Compare complete envelope costs, including waste, number of connections and equipment. For stock items, check lengths against the design; outlet stock needs a defect description. Equal 100 mm thickness does not make two orders equivalent.

Support spacing follows from loads and the selected panel’s properties. Read the complete relevant table conditions, including structural arrangement, colour and facing thickness. Supports also need suitable width and geometry. Matching core thickness does not justify transferring results from another panel type.

On site, check the first panel, joint alignment and washer compression. Do not compensate for a crooked frame by tightening harder. Plan edge closures at openings. Installation instructions help translate catalogue properties into a sound assembly; otherwise even a well-selected panel can form a leaking or uneven wall.

No. Example variants have U-values of 0.39 or 0.37 W/(m²K). Check the ordered panel’s own data.

No. Check the classification of the complete assembly for the product and installation method.
