screwing composite doorframe into cavity advice

[genomes]

Posted 6th May 2023 (Posted 12 m ago)


I am fitting a composite door and needed to take some bricks out as I wanted a wider door entrance .
Can I finish the bricks as

in the this photo ( tie brick to inner wall) as this will bridge the cavity gap and enable me to get a good strong fixing into the brick otherwise I will be screwing into an empty cavity space . I know I could wedge in blocks of wood into the cavity but I need a stronger fixing than that .Also would damp / water ingress travel the whole length of the brick and penetrate the inner wall fitting the bricks this way .Any tips greatly appreciated

this is the opposite side and I want the new composite door and frame to finish in the same existing position

No, the outer weathering course must not bridge the cavity.

You can buy frame fixing cleats that allow the frame to be placed over the cavity but fixed into the blockwork.
