CE marking of curtain wall brackets
CWCT has received enquiries about the need to CE mark curtain wall brackets in accordance with EN 1090 as they can be considered structural products.
Deflection of glazing in windows and curtain walls
There are no established limits on the deflection of glass used in windows and curtain walls.
The only clear requirement to limit deflection of glass in British Standards is given in BS 6180, which limits the displacement of glass in barriers to 25mm. This displacement would include any movement of the support to the glass.
