How Old Buildings Work: making the most of your traditional solid-walled building
There are over half a million traditional solid-walled buildings in Wales which make up 1/3 of the housing stock of the country. If you are responsible for their care and repair, either as their owner, or as a builder, you may be interested to learn that these old buildings (generally those built before 1919), do not keep the occupants warm and dry in the same way as a more modern cavity wall or timber frame home.
If you use modern render and paints on your old home there is a very real chance that you could be doing some serious damage by trapping water in the walls. Plus, wet walls are colder and so your home is more expensive to heat.
What you need is to have ‘breathable’ walls pointed or rendered in lime.
