<p>The insulating layer (1) is sheathed, both outside and inside, with a thin coating of fibre concrete (1', 1") with a naturally rough surface (R) made by spraying on the fibre concrete (2, 3) at least where rendering is required, with fibre ends protruding freely. The interior side of the coating may be smooth, with a formed surface (4). The rough parts may contain more fibres than the rest, or may comprise a sprayed layer consisting only of fibres. The ends can protrude between 3 and 10mm. Glass fibres with an alkali content are suitable.</p> |
