Evening all.   Short story is our balcony frames on the gables is made of 250 x 225 oak. The intention being to fit frameless glass balustrades (21.5mm lam/tough) in the associated channel. I have the glass and Posiglaze channels on site but when revisiting my building regulations i note the following condition 'Provide full balcony guarding details i.e. glazing and support posts and fixing 'details. 0.74 KN/m at 1100mm height not 1m.'   I'm yet to speak with building control
