If the wall thickness “Q” is less than
300mm cut the wall sleeve to the
required length.
Fit the wall sleeve.
Make good around the wall sleeve at
both internal and external wall faces
(through the wall sleeve if internal
access only is available).
If the wall thickness “Q” is greater than
300mm the wall sleeve must be fitted
flush with the INSIDE wall face. If the
inner end of the sleeve sticks out into a
cavity then, if desired, the wall sleeve
can be trimmed back to the depth of the
inner skin of the brickwork. Make good
at the internal wall face, leave the
external wall face until later.
