Proposal for development of unfired perforated brick as a humidity buffer in museum stores and archives, and possibly in exhibition halls. 1. How to make a 4m high wall of unfired bricks, attached to a wall in concrete or fired brick. The usual cavity wall building practice needs modification to take account of the weakness of the unfired bricks and the difficulty of gluing them together. (see article by Walker in the bibliography). 2. Develop a nice looking surface which is porous to water vapour. It must smooth over the perforations while allowing enough vapour penetration that the large internal surface area of the bricks is brought into play. 3. Work out a building design which gives a natural indoor temperature about 5C above ambient, to reduce the average indoor RH to around 55%. Consider using ground heat and solar heating. 4. Consider an alternative RH control by under-dimensioned dehumidification backed by RH buffering from the bricks. |
