External walls and panels

When constructing cavity walls considerations should include:

the local climatic conditions. Choose correct bricks, blocks, mortar and joint pointing for the site
the type of insulation used in the cavity. Is it full or partial fill? What width of cavity, if any, should be left clear? Does insulation need fixing back to blockwork?
the type of wall ties used and spacing
the position of damp proof courses - horizontal and vertical
the strength of blocks and the load imposed on them
that walls require restraint from buttresses, other walls, etc
pier sizes between openings and windows
that walls may require movement joints
that walls require fixing to floors and roofs with restraint straps
that suitable lintols are required above openings and
that padstones may be needed beneath beam bearings
