Panel Joint Methods Guide
Sandwich panel joints decide how boards assemble, seal and dismantle. This guide covers the three joint methods in the general range: tongue-and-groove joining, middle-aluminium joining and blind-panel ceiling joining. Handmade panels additionally offer middle-aluminium joints, tongue-and-groove joints and blind-panel joints as joint forms.
Tongue-and-groove joining
Tongue-and-groove joining is the machine-made route joint and suits cleanroom walls, ceilings and modular assembly. Boards assemble as a system and install quickly. For cold storage boards, a concave-convex chamfer structure is described as improving joint airtightness; name that requirement in the brief where airtightness leads.
Middle-aluminium joining
Middle-aluminium joining uses a middle-aluminium profile between boards and suits walls and boards that need a defined profile junction. Middle-aluminium tongue-and-groove boards pair this joint with face finishes in high-grade polyester, PVDF polyester and fluororesin paint, and face metals in galvanised sheet, 304 stainless steel, aluminium-magnesium-manganese sheet or aluminium alloy sheet.
Blind-panel ceiling joining
Blind-panel ceiling joining suits ceiling boards, where the ceiling must read as a continuous surface and allow ceiling services. Where a wall meets a ceiling, state the ceiling joint with the wall joint so the junction is planned. No drawing dimension is stated on this site; construction details follow the manufacturer's drawings for the order.
