Double Skin
DOUBLE SKIN
This is perhaps the most commonly used application for insulating an industrial building. The use of the metal outer sheet with its permutation of finishes and colours is complimented internally by using a bright white finished durable metal profiled lining panel. A cavity is formed using a galvanised metal spacer bar to which the outer profile is fixed. This is fixed to the cladding rails with a self-tapping / self-drilling screw and nylon spacer ferrule. The liner panel, also being fixed to the rail, forms the inner skin and the resulting cavity is filled with glass fibre insulation. Increasing the cavity and introducing an air gap has the effect of a further improvement 'U' value. It is also possible to use the cladding rail to act as the cavity-forming spacer. The outer sheet and liner panel are fixed to the rail's internal and external faces and the insulation is achieved using glass fibre and the air gap formed. This has the added advantage of hiding the cladding rails internally. This is an advantage especially in food production areas where the build-up of contaminating items on horizontal surfaces can be avoided. This also allows the inner wall to be cleaned quickly and efficiently.
