I was interested to read the "news" item "Experts warn of risk from unsafe window glass" (18 June, page 17).
You may be relieved to know that subscribers to National Building Specification have had the benefit of guidance on this topic for some considerable time. NBS guidance on general glazing identifies "five critical locations where safety glazing should be used, and recommends for each area a minimum BS 6206 safety glazing classification … [These include] low level glazing (excluding glazing in doors, side panels and balustrades)".

NBS guidance is distilled from information supplied by knowledgeable sources within the industry, and the above guidance illustrates that the problems associated with safety glazing are well understood by experts in this field.
