- Contemporary materials (particularly aluminum and plastic cladding systems) are
generally less robust, durable and dimensionally stable. Many of the initial versions of
these products introduced from the 50’s through the 70’s have proven not to age
particularly well. Vinyl and plastics tend to degrade due to exposure to light (UV),
and with aluminum the coatings fade and chalk. - Techniques of construction cladding are now more akin to “assembly”. Cladding
types are typically “systems”, with special installation requirements, and rely more
on “sealants” at material interfaces in part due to the greater movement of lighter
and less thermally stable materials. - Cement composite cladding and trim are durable, but require very specific
installation requirements (in terms of flashing and expansion criteria) in order to
maintain manufacturer’s warranties. They must be kept away from earth or standing
water, so careful detailing needed at grade and roof intersections with walls. Trim
boards are limited in thickness and width.
