Extract

As technology moves forward, new construction materials and methods are constantly being
introduced. The possibilities for moving away from conventional timber construction and utilising
prefabricated components manufactured from varied materials may be the way of the future. The
performance of a prefabricated extruded aluminium corner connection and its ability to provide an
equal means of weathertightness compared to that of conventional construction, a domestic three
stud, weatherboard clad corner has been investigated. Carried out using physical and analytical
testing, the prefabricated method of construction is examined for its ability to perform in regard to
thermal performance, air leakage and water penetration. The investigation identified that the
aluminium extrusions, in comparison to conventional construction provided a reduced thermal
performance in the current state of use due to the materiality (aluminium), provides better resistance
to air leakage when assembled in a double configuration and a better management of water
penetration through an ‘accept and manage’ principle, where by water which does penetrate is
drained away to avoid damage.
