Thats why we have developed a number of tables that detail all the information needed to work out the currect glass thickness.
You'll find all the tables on the Building Guidelines page. Heres how they work;
1. Firstly work out what hight your barrier needs to be. For this example lets take a landing in a single family dwelling property, in which case the barrier will need to be 900mm high. This can be found on the table titled 'Minimum barrier heights'.
2. Secondly different fitting scenarios require minimum loadings. For our example the table labelled 'Minimum horizontal' tells us we need a glass that meets a 0.36 kN loading.
3. The final table labeled 'Glass thicknesses' shows us the strength of different glass types. Therefore for our example if we are going to have toughened glass then we require 12mm glass.
It is nice and simple, if you do have any problems feel free to get in contact.
