SPAB Technical Note. The Need for Old Buildings to 'Breathe'
The Need for Old Buildings to ‘Breathe’ is the title of a Society for the Protection of Ancient Buildings (SPAB) Technical Advice Note and was written by Philip Hughes BSc, MRICS (Chartered Building Surveyor) and SPAB Scholar.
This document gives an excellent explanation of the differences between historical construction methods and materials and modern methods and materials. It describes extremely well the concept of 'breathing' materials, in the context of traditional construction and how their characteristics help prolong the life of historical buildings. It further describes issues relating to the introduction modern or impervious materials in the context of historical buildings and the issues this can cause.
It describes different applications from external render and pointing to internal plaster and paints as well as the nuances and gradations in the breathability of construction materials. It is not only a brief but invaluable resource for homeowners, designers and contractors dealing with historical buildings but also those looking to create modern buildings from natural or breathable materials.
