Hi all I am doing a loft conversion on my house for the past year and we have glass doors down stairs which the structural engineer said the doors will pass but I will need to install fire retardant glass. He said there are two types of glass I can use which are Pyro glass or wired glass. I don’t want to put the wired glass in these doors as this will look wrong in our house. So I would like to know if anyone knows where I can purchase this Pyro glass. Also I would also appreciate it if anyone could tell me if there is any other type of glass you can use as I have heard this Pyro glass is very expensive. If anyone known the price of this glass also then I would appreciate this as I require 12 one foot square peaces. Any help give will be appreciated.
