Long description

This figure has two parts. At the left part ‘a’ is a drawing of details of external insulation. It shows the corner of a brick-built building. A labelled sheet of polystyrene is shown covering the brick. At the corner of the building a labelled vertical ‘metal corner strip’ is shown. A sheet of labelled ‘mesh reinforcement’ is shown covering the polystyrene insulation. The mesh is secured to the wall by labelled ‘nails’. At the bottom a layer of labelled ‘render’ is shown covering the mesh reinforcement. The diagram shows that the bottom of the brick wall is not insulated. This is labelled ‘damp-proof level’. At the right part ‘b’ of the figure is a photograph of such an insulation system. It shows a wall with an inset window viewed from the outside. At the top right, thin sheets of pink foam insulation are shown attached to the wall surface with special fixing clips. At the bottom right a mesh reinforcement is shown covering the insulation. Immediately below the window the outer surface is shown covered with a thin layer of imitation bricks.
