As part of my extension self build I will shortly be installing a set of French windows with a fixed pane on each side of the doors.
The bricks I used for the walls are not solid, they have 3 holes in them.
The upvc is a 70mm frame and I was thinking of using 122mm Masonry Frame Fixing Screws (Toolstation 58193) which just needs a 6mm hole drilling but as the bricks only have about 25mm "meat" on them before the hole inside the brick, would I be better using a traditional 122mm Window Frame Anchor (Toolstation 25635) with the plastic sleeve instead ?
