EuroClad-Selekta is available in the following sizes:

Thickness (mm): 18
Length (mm): 5400
Width (mm): cover 155, sheet 170.

EuroClad-Selekta is manufactured in Germany by Werzalit. Only wood product from forests certified PEFC (Program for the Endorsement of Forest Certification) is used. This ensures that the manufacturing process is sustainable with regard to economic, ecological and social standards.

Pre-installation

HEALTH AND SAFETY

Take all necessary steps to ensure your safety and the safety of others:

ensure adequate ventilation or mechanical dust extraction when cutting or drilling
ensure the boards are well supported when cutting and nailing
wear appropriate safety equipment, clothing and footwear
use all tools in accordance with relevant instruction manuals
plan and monitor a safe approach for working at height; select and use the right equipment
clear the work area of any obstruction before work starts.

HANDLING AND STORAGE

Handling

Care must be taken during loading, unloading, and transporting the EuroClad- Selekta to prevent reinstallation damage.
Unload on-site by hand or hiab using fabric strops and protection to the product edges.

Storage

Store EuroClad-Selekta on a flat and dry surface, laid flat on bearers, with plastic underneath the bearers.
The EuroClad-Selekta should be stored in a dry environment and away from direct sunlight.
Make sure it is wrapped with a waterproof cover at all times. It is recommended to organise the site delivery close to the time it is being installed.

TOOLS AND EQUIPMENT REQUIRED

Install EuroClad-Selekta using standard carpentry tools and equipment.

Use tools in accordance with good trade practice and supplier’s instructions.

For accurate cutting use a drop saw with a fine-tooth tungsten carbide blade.

Installation

PREPARATION
Step 1: Building consent documentation
Access and view building consent documentation.

Step 2: Framing substrate
Ensure that the substrate is straight and true and within the framing tolerances described in NZS 3604:2011, section 2 and Table 2.1 or NASH Design Standard: 2019 Part 2, section 2.5.
For horizontal applications, studs must be at maximum 600 mm centres, with nogs and dwangs fitted between the studs at maximum 800 mm centres.
For vertical applications, studs must be at maximum 600 mm centres, with nogs and dwangs fitted between the studs at maximum 480 mm centres between the top and bottom plates.
Where eaves are to be used, ensure a line of nogs or dwangs are installed below the soffit drop for top edge fixings.
Ensure the framing moisture content is less than 20%.

Step 3: Building underlay
Ensure the building underlay installed complies with Table 23 of Acceptable Solution E2/AS1.
A rigid air barrier that complies with Table 23 of the Acceptable Solutions E2/AS1 must be installed where the EuroClad-Selekta is to be used in an extra high wind zone.

Step 4: Flashings
Ensure the flexible flashing tapes are compatible with the building underlay and suitable for the specific location.
Ensure all necessary flashings are installed, pipe and flue penetrations and back flashings are installed at all corners and head flashing stop ends are installed at windows and doors.
Install air seals to holes, penetrations and voids using backing rod to suit the gap and sealant.
Excess sealant should be trimmed.

Step 5: Cavity
Where the installation includes a cavity, ensure the correct type of cavity battens are installed for the required orientation of the cladding in accordance with the EuroClad- Selekta cladding specification guide.
Ensure the cavity closers are installed continuously around the bottom of the cavity.
The top of the cavity must be closed off.

INSTALLATION

Step 1: Details
Access and view EuroClad-Selekta details in the building consent documentation or access the relevant details from PSP.

Step 2: Board set out
Horizontal application board set out

For horizontal applications use a story rod or laser level to set out the boards most practical layout. This will assist when establishing alignment with a mid-floor, window head and other critical horizontal junctions.
Layout the boards to ensure the bottom edge of the planks overlaps the floor level by 50 mm and is a minimum of 175 mm clear of unpaved ground. For roofs and decks a minimum clearance distance of 35 mm must be maintained.

Vertical application board set out

For vertical applications, set boards out from the centre of the wall and install outwards to the corners.
Layout the boards to ensure the bottom edge of the planks overlaps the floor level by 50 mm and is a minimum of 175 mm clear of unpaved ground.
For roofs and decks a minimum clearance distance of 35 mm must be maintained.
For two storey timber floor buildings, install a mid-floor transition flashing.

Step 3: Cut boards
Once the layout is established, cut boards as required.
Where boards are scarf jointed, they must be installed over supporting timber.
Prime cut ends with EuroClad-Selekta Sealer.

Step 4: Board fixing
Fix boards to timber framing

Start fixing boards near the middle and work outwards towards the ends.
Fix each board with one 6 g x 50 mm stainless screw per board at every stud or nog.
Use only one fixing per board per stud to allow for movement.

Fix boards to steel framing

Start fixing boards near the middle and work outwards towards the ends.
Where fixing to lightweight steel framing, use fixings recommended by the steel framing supplier, ensuring they are a maximum gauge of 6 g.
All lightweight steel framing must have a thermal break with an R-value of no less than R0.25.
Use only one fixing per board per stud to allow for movement.

Fix boards around joinery

Preinstall the head and sill flashing.
Fit the window or door into position, ensuring the bottom edge is well supported with a WANZ bar or a timber batten.
Allow 19 – 20 mm clearance from the face of the cavity batten and the back face of the joinery facing.
EuroClad-Selekta weatherboards can be preinstalled before or after the joinery is fitted. Whichever option is selected, ensure the board edge has a minimum of 10 mm cover behind the window facing.
Use a compressed foam seal, foam plugs or scribers between the board and the window facing.
A continuous compressed foam air seal can be installed from the inside of the building.

Fix boards around penetrations

Allow 5-6 mm minimum clearance around all penetration.
Prime all cut ends and edges with EuroClad-Selekta Sealer.
Install a bead of flexible structural sealant between the cut edges and the penetration.
Install an over flashing where possible to protect the sealant and add an additional layer of protection.

Fix boards at junctions

Ensure allowance is made at each junction for movement (1 mm/m).
All joins must be made over a framing member.
Use EuroClad Edge or Connector joiners.
Do not place junctions on drip lines e.g., under the side edge of a window.

QUALITY CHECK
Check the cladding system to ensure all components are installed correctly and in accordance with PSP details.
Ensure all information is available for the building owner to maintain the cladding system.
