There are three main types of metal cladding systems; profiled sheeting, cassette panels and composite panels. These three choices offer the most concise cladding solutions to Architects and specifies here in the UK and overseas.
The most effective and concise way to classify metal-based cladding systems is by their method of manufacture. Best cladding for homes can fall into one of following three categories:
- Profiled Sheeting
- Cassette Panels
- Composite Panels
Profiled sheeting is one of the most common cladding panel systems and has been in use for decades. Steel or aluminum is normally used for profiled sheeting. It can be applied to both roof and walls, in each case the performance requirements vary.
On roofs the sheeting can be susceptible to greater solar gain; this can mean thermal movement which has implications for end laps between sheets and their fixings. The roof will also be subjected to foot traffic during both installation and routine maintenance. The finish therefore has to be designed for greater toughness, stability and to minimize corrosion. On walls, as they are more visible, the color fastness of the finish is more important.
A major factor in the success of profiled metal cladding systems was the development of self-drilling and tapping screws which enable the rapid and secure fastening of the sheets from one side.
Conventional bolts and hooks are much slower to install requiring access from both sides of the sheet. Most screws are carbon steel with some form of metallic or metallic and organic coating to improve durability. Washers and heads are incorporated in screw. The screw heads can be covered with plastic caps to match the color of the steel cladding system. There are many varieties of screw, of different lengths, cutting heads and thread pitch and depth, depending on the type of best cladding for homes the substrate to which it is attached and the type of insulation used in the cladding panel system.
There are a range of proprietary composite cladding systems available in the UK, generally there is little difference in the actual core and facing material, the major differences lie in the joints between panels, the range of sizes and the range of architectural features such as corners and curved panels that are available.
Panels can also be laminated; this process applies to the other core materials. Adhesive is applied to the steel faces and pre-formed slabs of insulation. The panels are then clamped together either in a press or by passing them through a series of rollers.
