Even as corrugated sheeting continues to be a popular finish for barns and industrial-style projects, there’s a wide array of metal cladding systems today that meet various requirements, ranging from new building surfacing to aesthetic enhancement for existing structures.
In any case, metal cladding is a task for specialists. It’s important for the team to focus on elements such as lapping, liners, flashings, etc. The following are the primary routes:
As the name implies, this type of cladding is put together on site. It typically has four main components: a thin internal liner to keep air out; insulation (mineral wool is common); spacer bars/brackets for keep the finish stable; and the outer facing sheet, which shields against the weather.
Quality workmanship is the secret to this system’s success, both in appearance and function.
These ready-made cladding elements come as complete panels, so installing them will be fairly quick and simple, though a specialist contractor will still be needed for the work. They come with an insulating foam core, generally of high-quality polyisocyanurate (PIR), which stick hard to the internal and exterior skins.
You can pick between flat or profiled facings in a whole array of colors and coatings, and the panels can be screwed into place or installed secret for a smooth appearance.
As composites, these panels are insulated and come with liners. The biggest difference is that they have user-friendly interlocking jointing systems that allow speedy installation.
This system has no exposed mechanical fasteners joining adjacent metal sheets. It has a certain type of weathertight clipped joint instead, and it creates a unique projecting seam that may run horizontally, vertically or diagonally. This cladding type can be delivered as pre-insulated panels or as sheets of material formed and crimped on site before being applied to plywood or any equivalent substrate.
The second method has an advantage: it gives you the freedom to use a design you want, from curves to unbroken finishes on roofs and walls, and so on. However, you need to bear in mind that it needs a a lot more expertise on site.
Metal cladding can also be made in rainscreen format, in which case, the outer face is lightweight and bears no load. It’s has an airtight and insulated backing but kept separate from this primary structure by way of a ventilated cavity that safely drains moisture away. Rainscreen cladding reduces the possibility of condensation, making it a good option for existing structure upgrades, while allowing for lots of design flexibility.
