Mineral wool core sandwich panels
Some buildings need more from their envelope than protection against cold. In production halls, around technical rooms and at fire compartment boundaries, material behaviour at high temperatures is important. Mineral wool core sandwich panels combine non-combustible insulation with factory-finished facings and, in a suitably constructed partition, can also help reduce sound transmission.
1 A non-combustible core as a design advantage
Mineral wool introduces no combustible foam into the core. This is valuable when designing buildings where fire protection requirements strongly influence the choice of envelope. The fire resistance of the complete wall still depends on the particular panel, joints, fixings and supports, but a mineral core offers useful options. Its non-combustibility distinguishes it from EPS and PIR core panels. It allows investors to combine the required protection with the convenience of a finished insulated envelope. Sandwich panel construction can therefore remain practical when enclosing rooms containing process equipment or buildings with enhanced fire safety requirements.
2 A fibrous structure that contributes to acoustics
The spaces between wool fibres allow part of the energy of air vibrations to dissipate. In a properly designed partition, the wool works with the mass of the facings to reduce noise transmission. This is useful between a workshop and offices, around fan rooms or in halls adjoining areas that need quieter conditions. Results depend on the entire assembly, so compare the declared sound insulation of the panel rather than the core name alone. Mineral wool can combine thermal, acoustic and fire requirements within one envelope type. This reduces the need for different systems where several requirements apply to the same wall. The combination is especially useful between production and administration areas: one partition can help divide space, reduce noise and provide thermal protection.
3 A finished envelope for demanding use
Metal facings protect the core and create surfaces that can be used without plastering. This helps keep industrial support areas orderly and shortens the interval between enclosing a hall and fitting it out. Mineral wool panels are generally heavier than lightweight foam-core versions, but offer properties that matter in more demanding buildings. Where minimum insulation thickness is the priority, PIR may have an advantage. Where a non-combustible core, finished surfaces and documented acoustic performance are needed together, mineral wool is a strong candidate. The choice follows the building’s function rather than the square-metre price alone.
SteelProfil offers mineral wool sandwich panels and a broad selection of first- and second-grade materials available from stock. Promotional offers and competitive prices help compare available versions against project requirements. We match the offer to partitions where the non-combustible core has practical value.
