Paints & Film Forming Stains
Penetrating Stains
Shadowclad is available in an uncoated panel or with a factory
applied exterior grade performance coating. For best results
use high-quality paint or stain systems and always refer to the
coating manufacturer recommendation prior to application.
Three coats (1 undercoat, 2 top coats) of a good quality,
100% acrylic paint system with a light reflectance value
(LRV) of 50% or greater (ie light colours) which is regularly
maintained will provide the highest level of protection and
durability for Shadowclad and is likely to require the least
amount of coating maintenance over the life of the cladding.
Dark colours (LRV of below 50%) may still be used, however
they will need extra maintenance.
Penetrating stains show the natural texture and character of
timber and are widely used on Shadowclad Exterior cladding.
Penetrating stains offer less protection for panels from exterior
weathering than paints and film forming stains, which are
considerably thicker in surface film build.

SUSTAINABILITY
Shadowclad is manufactured from sustainably-grown New Zealand plantation pine. Unlike other
composite alternatives that are carbon intensive to manufacture, Shadowclad is a low embodied energy
product that is actually a natural carbon store and helps reduce our impact on the environment.
Environmental Life Cycle Analysis (LCA) is
recognised as the preferred cradle-to-grave
basis for comparing the environmental impact
of products, including building materials. On a
limited LCA basis, building in wood sourced
from sustainably-managed plantations represents
a net removal of carbon dioxide away from
the atmosphere for at least the life of the
structure. As such, building in wood sourced from
sustainably-managed plantations can therefore
make a positive contribution to combating
climate change.
C001316
As sustainability continues to become more
important to both the architectural and building
community, Carter Holt Harvey Woodproducts
continues to search for methods of ensuring
that our customers and end consumers receive
products that have minimal impact on the
environment. Because we choose independentlyaudited and measurable processes, you can be
confident that we take this responsibility seriously.

TECHNICAL NOTE
November 2015
S U I TA B L E WA L L C L A D D I N G O P T I O N S
Guidance on the suitability of particular cladding systems are not provided
via the NCC 2015, Building Code of Australia – Volume Two. However,
compliance documents for the NZBC Clause E2 External Moisture,
Acceptable Solution AS1 (NZBC E2/AS1) do provide direction regarding
the suitability of wall claddings used in direct fix or cavity wall construction.
The use of cavity wall construction or direct fix claddings is driven by risk,
first whether the structure is exposed to conditions that may be conducive
to moisture ingress, and second by mitigating factors such as the existence of
a secondary line of defence through a drained and bottom vented cavity in
the case of cavity wall construction. Following guidance from NZBC E2/AS1,
CHH Woodproducts recommends the use of cavity wall construction over
a nominal 20 mm drained and bottom vented cavity for fixing Shadowclad
on structures exhibiting a risk score less than or equal to 20 (Cavity wall
construction, risk score < 20). CHH Woodproducts only recommends
Shadowclad be direct fixed when a risk score of less than, or equal to 6 is
achieved (Direct fix cladding risk score, < 6).
Further, CHH Woodproducts recommends the use of a rigid air barrier
where wind speeds exceed N3 or C1 as defined in accordance with AS
4055, Wind Loads for housing and for risk scores above 20, specific design
is required.
CO N C LU S I O N
Important Notice and Warning
Decisions around the use of direct fix or cavity wall construction for
claddings, like Shadowclad, is paramount in the ongoing weathertightness of
a building solution. The NCC 2015, Building Code of Australia – Volume
Two has introduced the concept of cavity wall construction in the May 2015
edition through risk factors and scores. However it stops short of providing
guidance on when to use, or not to use, direct fix or cavity wall construction.
While the products in this document possess the characteristics described, no
representation is made that the products will be effective in all locations and
circumstances. Much depends upon building design, construction practices and the
environment in which the products are used. Statements about the attributes and
performance characteristics of the products are made on the assumption that the
products are properly stored, handled, installed, used and maintained in their relevant
application.
CHH Woodproducts recommends applying the rules from the NZBC
relating to the use of cavity wall construction. The following rules apply for
application of direct fix or cavity wall construction relating to the risk score
from Table 1:
You should not rely solely on this document when using the products. Carter Holt
Harvey recommends obtaining professional building advice which takes into account
your particular circumstances and site conditions. Carter Holt Harvey is not involved
in, and does not assume responsibility for, the selection, installation or maintenance
of our products in situ.
• Where risk score < 6 Shadowclad may be applied as a direct fix cladding
• For risk scores 7-20 Shadowclad shall be installed on cavity wall
construction
• For risk scores >20 specific design is required.
Failure to install Carter Holt Harvey products in accordance with applicable building
regulation requirements and instructions may lead to personal injury, loss or damage,
and may adversely affect the performance of the products.
See Important Notice and Warning above.
Information contained in this document is specific to the Shadowclad® range of plywood products and must not be used
