Buildings are commonly over-clad to improve their appearance, to increase thermal insulation, and to reduce maintenance costs. This publication reviews the use of light steel construction in the over-cladding of existing concrete and masonry buildings as part of a renovation process. The over-cladding systems use sub-frame members that are connected to the existing structure or cladding. The new facade is attached directly to the subframe members. The sub-frame members are assembled from galvanized cold formed steel components, and a variety of different cladding materials may be used. The design aspects for over-cladding systems are reviewed, and the use of steel in over-cladding is discussed. A series of Case Studies from Belgium, Canada, Denmark, Finland, Germany and the United Kingdom are presented to show the range of applications of light steel in over-cladding. A prototype steel intensive over-cladding system is described, and interim results from the testing of this system are reported. It is demonstrated that in most cases the cost of the over-cladding will be re-couped within a 20 year period, if all the potential savings are considered.
