Weatherboard cladding: ventilated with sarking
Weatherboards as an external cladding, fixed to provide a
ventilated draining cavity between the boards and the vapour
permeable membrane. The ventilated cavity is necessary in
high wind areas, or where driving rain or persistent damp is
prevalent. It is common practice in Europe.

Slatted cladding: ventilated with
sarking
Spaced boards as an external cladding, fixed to
provide a ventilated draining cavity between the boards and
the vapour permeable membrane. The ventilated cavity is to
ensure that water dries out or drains from behind the
boards. Care is needed to ensure that the sarking is
completely sealed and sufficient to provide effective
weather protection. The boards are usually allowed to
weather naturally.

Plywood cladding: flashing at
aluminium window
Flashing plywood lining to aluminium windows
requires careful detailing as many stock window sections are
designed for brick veneer. An additional purpose made
flashing should be used between the end of the ply, the
window and the sarking

Internal weatherboard corner: butt to
stop bead
Weatherboards butted up to a rectangular bead at
the internal corner. Flashing needs to be run behind the
joint to shed any water that penetrates.
|
|
|
External weatherboard corner: butt to
stop bead
Weatherboards at an external corner butt into a
corner stop bead. Flashing needs to be run behind the joint
to shed any water that penetrates.
|
|
|
External weatherboard corner: double
cover plates
Weatherboards at an external corner run into each
other before being covered with cover boards. Scribed boards
may be used in addition to the cover boards. Flashing needs
to be run behind the joint to shed any water that
penetrates.
|
|
|
Internal weatherboard corner: mitred
or scribed
Weatherboards mitred or scribed at the internal
corner. Flashing needs to be run behind the joint to shed
any water that penetrates.
|
|
|
External weatherboard corner: mitred
Weatherboards at an external corner mitred
together at the joint. Flashing needs to be run behind the
joint to shed any water that penetrates.
|
|
|
Internal weather board corner: butted
vertical boards
Vertical weatherboards are mitred, scribed or
butted at the internal corner. Flashing needs to be run
behind the joint to shed any water that penetrates.

Weather board cladding: fixed over
building paper.
Weatherboard as an external cladding, fixed to a
timber frame over a waterproof but vapour permeable membrane
(sarking). This barrier provides additional protection from
water and keeps out the wind. Weatherboards come in a
variety of profiles and sizes, in a range of species. Non
durable species can be used but need to be painted.

Slatted screen
Boards fitted to frames to provide a slatted
screen. Here, rectangular pieces are fixed close together.
|
|
|
Slatted screen
Boards fitted to provide a slatted screen, here
square pieces are spaced apart to form a more open
screen.

Plywood cladding: horizontal joint
with flashing
Plywood cladding is available in many different
finishes and it is joined in a variety of ways. Sheet metal
Z shaped flashing is installed between the plywood sheets
and stops moisture from entering the building. The cover
strip is discretionary.
|
|
|
Plywood cladding: lapped horizontal
joint
Plywood cladding with a shiplap edge used either
horizontally or vertically. The shiplaps are best installed
facing away from the prevailing weather. The cover strip is
discretionary.
|
|
|
Plywood cladding: vertical joint with
cover strip
Plywood cladding with a vertical butt. This can
be a simple butt or include a shiplap. The cover strip is
necessary for simple butt joints and is often used to good
architectural effect.
