I have an aluminium patio door on order and i’d like to know best way to secure. It’s a cavity wall so could wedge wood blocks in the cavity and screw into that. But I’m thinking that the wedges could go loose as I screw into them. Are there any bespoke solutions out there that fit secure in the cavity and allow me to screw frame into. Or maybe screw at angle into outside brickwork, but I don’t like that idea because perhaps frame could become distorted.
Thanks as usual.
