Creating an air tight building envelope
This Colour Coat Technical Paper shows designers and constructors how a good level of air tightness can be achieved using Colourcoat pre-finished steel products from Tata Steel. It provides a short overview of the Part L Building Regulation requirements for air-tightness and practical guidance on the common methods of jointing both built up and factory insulated composite panel systems.
Environmental concerns and the rising cost of fuel mean that there is an increased focus on minimising energy use during the life of a building. Thermal performance of the building envelope plays a key role in this. This technical paper shows designers and constructors how a good level of air-tightness can be achieved using pre-finished steel products.
