Though corrugated sheeting is still a popular finish for barns and industrial-style projects, there’s a whole variety of metal cladding systems out there to serve different purposes, whether it’s surfacing new buildings or improving existing structures.
In any case, metal cladding is a task for specialists. to ensure efficiency and ease of maintenance of the weatherproof covering. Below are the main routes:
As the name indicates, this type of cladding is tacked together at the work site. It is often composed of four primary components: a thin internal liner for air tightness; insulation (typically mineral wool); spacer bars or brackets for supporting the finish; and the outer facing sheet for weather protection.
Quality workmanship drives success for this system, both functionally and aesthetically.
These prefabricated cladding elements are provided on site as complete panels, which means installation will be fast and simple, but a specialist contractor is still necessary for the work. They are made with an insulating foam core, mainly of high-quality polyisocyanurate (PIR), which adheres instantly to the external and internal skins.
You will be able to choose between profiled or flat facings, which are available in a large variety of colours and coatings; and the panels may be screwed to place or discreetly installed to create a seamless look.
Just like composites, such cladding panels are made with insulation along with liners out of the box. The main difference is that they have easy-to-use interlocking jointing systems that will make for super 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 kind of cladding may come as pre-insulated panels or as sheets of material which are shaped and crimped on site, and then combined with plywood or another substrate.
With the second method, you have a big leeway for design expression – you can include curves, unbroken finishes and so on. But do take note that this will require a much higher level of expertise for good workmanship.
Metal cladding is also available in rainscreen format, where the external face weighs light and bears no load. It’s joined with an insulated, airtight backing, but detached from this key structure using a ventilated hollow area intended for harmless draining of moisture. Rainscreen cladding controls condensation risks, making it a very popular choice for upgrading existing structures, while offering a lot of room for design preferences.
