I read with interest the article on the revival in glass blocks (AJ 19.10.00).This was especially relevant because I recently gave a talk at the CUBE in Manchester on the history of glass blocks which runs parallel to that of Luxcrete.
This history traces back to 1898 and involves Frank Lloyd Wright who was retained as a designer of glass prisms.
There are a few points on which I must comment.
Technical and constructional data of good quality is available from the established manufacturers and specialists.
No current British Standard exists, but I act as a UK delegate (elected by the British Standards Institute) on European (CEN) and international (ISO) working groups drafting new standards for the product.The first document is prEN1051-1 and is due for implementation in the near future. It will cover the manufacture of glass blocks.The document is well advanced and also covers the construction of glass-block walling, flooring constructions and prefabrication.
Product literature in English is readily available.
There is product performance information covered by the extensive literature available and includes panel restraint, panel sizes, fire performance, and so on.Trained technical staff are available to help.
It is not always necessary to reinforce every horizontal joint.
For any further information about glass blocks, I and my staff will be pleased to help.
