Poroton blocks are a special clay block used to build highly insulated walls without a cavity. The blocks have a honeycomb-
Clay is naturally a very good material at regulating humidity, absorbing and releasing moisture readily. It is sometimes used as an internal render in buildings, specifically for this purpose. The Poroton blocks work by being ‘breathable’, i.e. being able to transfer moisture from inside to outside, thus eliminating the need for the residual cavity used in traditional masonry walls.
The insulating properties of Poroton blocks are provided by tiny voids within the clay. These are formed by mixing sawdust with the clay before it is moulded. When the blocks are fired at high temperatures to cure them, the sawdust burns and disintegrates, leaving voids within the clay.
The most efficient way of building with these blocks is using a special thin-
The finishes used on the external walls are important in order to preserve the breathability of the wall. This generally means using some type of lime or mineral-
As there is no specific insulation layer used in the wall, external walls are usually 365mm or 425mm thick in order to achieve a U-
