Werzalit Ventilated and Drained Cladding System
Siding profiles by Werzalit of America, Inc. are both high quality design elements and
protection.
Werzalit of America, Inc. cladding boards can handle whatever the weather throws at them.
With their robust and impact‐resistant surfaces, they protect a building structure against
weathering influences. Styled to match traditional wood lap siding, these panels interlock in a
precision tongue‐and‐groove design, complete with a closed cell gasket system to turn away
wind, air and water infiltration to a degree not matched by natural wood or any commodity
siding product. The siding profiles stand for design freedom, and their painted surfaces ensure
simple, quick installation. Used as partial or full facade, they offer their advantages to new
buildings as well as in modernization and renovation.

Naturally Resistant: Werzalit Wood Based Material
Cladding is the face of your structure. And so
that it doesn’t suffer the damages caused by
wind, weather and extreme temperatures, it
needs special protection. This in turn makes
huge demands on construction materials:
They need to be weather‐resistant, light‐fast
and impact resistant. Werzalit combines all of
these qualities into one material. Our
patented manufacturing process makes this
possible – a process that combines the natural
qualities of native deciduous and coniferous
trees obtained from sustainable forestry
sources with the resistance of top quality
resins. The result is a high‐density wood
3
material evenly structured throughout, which
is exceptionally resistant to extreme weather
conditions and mechanical stress.
To ensure that, Werzalit products maintain
their properties, they undergo endurance
testing‐under the toughest conditions. In the
case of Werzalit cladding profiles, this means
testing in the laboratory and at outdoor
weathering facilities for the effects of extreme
sunlight and extreme tropical humidity.

Economical: Werzalit’s Construction System
Horizontal, vertical or diagonal construction or
traditional weatherboarding, available in custom
colors, Werzalit’s siding opens up a world of
versatile design options. Used as partial, full or
weatherboard cladding, they make an impact
when used for new‐structures as well as
modernizing and renovating property. Creative
cladding designs with Werzalit pays for itself from
the first day. The cost‐effective construction
system fits and secures very easily to the sub‐
frame. Its homogenous surface has no
honeycombing, voids or resin pockets, keeping
waste to a minimum.

The high degree of prefabrication also saves on
time and cost during installation. Its acrylic
surfaces and décor designs are already lacquered
to environmentally‐friendly standards in the
factory, so that further processing is unnecessary.
Werzalit cladding profiles are a highly compressed
and homogeneous material core as well as having
a robust surface coating made of a high‐quality
acrylic system with light‐fast color pigments.

General Description
Engineered for Protection and Beauty
For the first time, materials designed to protect high rise buildings from the extremes of wind and driving rain are
incorporated in a traditionally-styled residential cladding system
Styled to match traditional wood lap siding, these panels interlock in a precision tongue-and-groove design,
complete with a closed cell foam gasket system to turn away wind, air and water infiltration to a degree not
matched by natural wood or any commodity siding product.
Trim Completes The Package
Unique Gasket System Offers Unsurpassed Weather Resistance And
Reduced Air Infiltration
Overlapping panels fit together with a tongue-and-groove design. A factoryinstalled
compressible gasket keeps even the nastiest weather outside where it
belongs
Manufactured With Protection To The Core
More resistant than natural wood or hardwood,
stronger than cement board . . . will not warp,
buckle or check, blister, flake or peel. Superior
damage protection from hail, ice and wear.
Perfect Joints Built Right In
Every panel comes with a built-in lap joint
to ensure a finished look that reduces
unsightly gaps and weather infiltration.
Our cladding system can be combined with wood or aluminum
conventional trims or with Werzalit factory pre-finished trim
systems to make a complete exterior package. The WAGS trim
systems use compressible foam gasket to reduce air infiltration at
window, door and other openings.

Panel Dimensions
Werzalit panels are engineered to accommodate expansion and contraction due to
seasonal effects of temperature and humidity on its wood core. Panel ends are routed to
form a shiplap end joint. It is not necessary for panel joints to end over a stud.
NOTE:
1. The recommended gap between shiplap panel ends is 1/8” for temperate, cold or arid climates and
3/16” for tropical climates.
2. Panels installed in runs up to 36 feet long may be butted if normal expansion is provided at the end
of the runs.
3. Joints up to 3/8” provide no technical problem, but may be unsightly.
4. To give the best appearance, gap spacing should be uniform throughout the job.
5. Work should be planned to avoid an excessive number of joints in conspicuous locations or an
unsightly pattern of joints.

Cladding Application - General
CLADDING INSTALLATION
All Werzalit cladding and accessory installation shall be
in accordance with approved practice and local building codes.
STORAGE
Cladding must be stored in a clean, dry area out of the
weather and away from any damaging activity. All cladding
bundles should be stored above ground on level blocking allowing
ample space for air circulation. Covering should be used to protect
panels from the elements during exterior storage. Wet boards
should be removed from bundles to allow them to acclimatize prior
to installation (stand boards on edge for several days, allowing air
circulation on all sides).
WALL SURFACE EXTENSION
Existing wall surfaces must provide a flat plane for
proper installation of Werzalit cladding. Irregular and unlevel wall
surfaces should be brought to the attention of the project
supervisor.
CUTTING
All Werzalit architectural products are easily installed
with ordinary carpentry tools. When power sawing, a sharp carbide
tipped saw blade should be used. Exposed edges of all cross cuts
and cut-outs should be touched up with a top quality exterior color
matched coating.
NOTE: Always cut into the finished surface!
SUPPORT FRAMING
Werzalit cladding and accessories require a supporting
framework with a maximum spacing of 2’-0” O. C. All sub-frame
construction or support framing shall be no less then 5/8” thick,
securely anchored and properly aligned to provide a flat plane for
the cladding attachment.
WALL PROTECTION
An exterior moisture retarder shall be applied over the
construction wall surface.
Wall openings for windows, doors, louvers, etc. should
be flashed according to the manufacturers instructions and good
building practice to prevent moisture penetration between the
fixture and the rough wall opening.
LOW COMPRESSIVE STRENGTH SHEATHING MATERIALS
Werzalit can be installed over low compressive
sheathing such as plastic foam or foil faced materials, providing
that the following conditions are met:
1. Cladding must be fastened through the sheathing,
securely into the framing material.
2. The starter rail must be attached directly to the framing
member, not foam sheathing.
3. Care must be taken not to overdrive cladding fasteners,
or sheathing may be damaged by compression and wall
surface may be uneven.
EXTRUSION ACCESSORIES
Install all extrusions as called by the architect. All
extrusions shall be positioned plumb and level assuring proper
alignment of cladding panels with all outline edges.
PANEL PLACEMENT
Place panels firmly together with tongue and groove
mating fully. Panels can be seated fully by tapping into position
with the end of a hammer handle. Before securing into position,
make sure allowance has been made for expansion and
contraction.
Panel ends can be placed at random or placed in a preplanned
pattern.
EXPANSION AND CONTRACTION OF PANELS
Werzalit has provided an engineered expansion and
contraction system for its architectural panels. This allows the
panel to “work” with climatic changes and allows the panel to be
straight and smooth. For further details see page 8.
FASTENING
1. When fixing Werzalit panels directly to wood framing,
use stainless steel fasteners, with a minimum ¾”
penetration into framing or solid sheathing. For
application over sheathing or insulation board, fastener
size and length shall be adequate to support panels and
provide sufficient penetration (min. ¾”) into the framing
material.
2. Whether by hand or power driven, a snug contact with
the panel will secure installation. In all cases, avoid
overdriving fasteners whereas this will hinder lateral
movement of Werzalit panels. Fasteners shall be
inserted at right angles to the panel to assure that
fastener head is flush to the surface allowing next panel
to be seated properly on tongue.
NOTE: When power nailing use a finishing nail gun
with air pressure not to exceed 85 psi
Fasteners recommended by Werzalit of America, Inc. are a #7
stainless steel finish screw similar to those manufactured by Swan
Secure, Inc..
Stainless steel nail fastener, ring-shank 8d, length to be
determined by the installing contractor.
TOUCH UP PAINT
1. Color matched touch-up paint is provided by
manufacturer. All field cut ends and cut outs must
be painted by the installing contractor.
2. When Werzalit of America, Inc. siding is installed
against wood or synthetic trim it is recommended
the exposed end of the siding board be field
painted by the installing contractor before
installation.
3. Weather caulking should be used to cover the
expansion gap between the siding and the trim
material. Color matched touch-up paint should be
used to hide the caulking material.

Typical Horizontal Installation
This diagram shows a typical installation of horizontal cladding, numbered in the normal
sequence of operations. Note that corner posts, either aluminum or wood, are required
for proper installation. The first panel is mounted on a starter rail. It is not necessary for
panel ends to coincide with stud spacing, as the tongue & groove design with shiplap
ends provides a self-supporting finished joint. This reduces waste and labor cost,
providing fast and easy installation.
1. Install Aluminum Trim (Inside &
Outside corners, window, door trim, etc .
)
NOTE: Windows and doors should be installed
according to the manufacturer’s recommendations
and good building practices to prevent water
intrusion between the rough opening and the window
or door unit. Details may vary with climate and
manufacturer’s design. Werzalit of America, Inc.
does not provide flashings, drip caps or other material
for this purpose.

Pre-finished Werzalit Trim Boards create a lasting impression!
Moisture, changing temperatures, UV light and insects attack exterior trim and cut short its useful life.
Werzalit trim boards however, are another story.
New technology has created a polyvinyl chloride (PVC) material that won’t swell, rot, split, delaminate,
cup or craze under harsh conditions. Yet it’s as workable as wood. You can nail, glue, drill, route and cut
Werzalit Trim Boards using the same tools you would use with wood.
Werzalit Trim Boards match woods ability to adapt to varying needs, but when it comes to durability,
there’s no comparison. Because of Werzalit Trim Boards outstanding lasting power, they are the right
choice for these and other applications:
* Fascia * Rake, Corner and Frieze Boards
* Decorative trim and columns * Flat panels
* Fluted and flat casings * Fencing
* Custom millwork * Sheet rock
* Moldings * Gingerbread
* Soffits
Werzalit Trim Boards don’t require an expensive investment in new tools or fasteners; you can work these
products like real wood.
