Sandwich panels, something akin to the process of lamination, basically describes a core of thermally efficient material, sandwiched and bonded between two outer layers of pre-stressed ‘skins’ of the metal sort. That does help explain why sandwich panels are in such demand for industries where hygienic insulation is the name of the game.
Limited only by transport or handling restrictions, the manufacturing process achieves the exacting flatness and dimensional tolerances for each kind of application.
Engineering and Sandwich Panels
Insulation applies to way more than keeping things cool on the ground. The aeronautics industry makes extensive use of sandwich panels. Nowhere could there be a more exacting industry for engineers to test their mettle than the field of aerospace. Who would have figured that sandwich paneling could find such a perfect fit?
Thanks to thorough trials, sandwich panels are fully understood by this industry in relation to formation processes that influence compressive, flexural – an interesting word that, and impact strength.
Distinguished by stiffness and core thickness, the panels are lightweight and possess that magical flexural strength. Flexural strength describes the modulus of rupture, or bend strength, or transverse rupture strength as a material property, defined as the stress in a material just before it yields in a flexure test. Thanks to the variables possible in their spatial structure and thermodynamics, aeronautics use sandwich panels, as do ships, vehicles, and construction companies.
Should any specifics be required by consumers who include Isowall (a world leader in sandwich panels who use Rockwool mineral wool coring) they ‘can be confident that they have chosen the most extensively tested and proven panel system in the marketplace,’ according to Specifile.
Regular use of Sandwich Panels
With a material that can be so customized, it is noteworthy that more basic variants have become more readily produced for us more regular consumers. The differences boil down to fewer core materials, which essentially include:
- Expanded polystyrene (EPS) -v more effective with added fire retardant (FR).
- Mineral wool – great for soundproofing and fire resistance with added retardant.
- Phenolic foam – a mix of EPS and resin for improved fire resistance.
These more commonly manufactured panels vary in core type, thickness, profile, length protective coating, and cladding colour. Suffice it to say that, whether you are needing cold storage for your company, or you need to soundproof your garage for your son’s ‘boyband’, sandwich panels could be just the right fit for you.
