Installation Guide

Palliside Weatherboards are generally quick and easy to install. However care must still be taken to ensure that the weatherboards are level and the correct accessories and installation methods are used.

Due to the recent changes to the Building Code, there have been some changes to the installation of Palliside Weatherboards to meet the new requirements. These changes include new accessories around openings (Sill Tray, Jamb Flashing Base/Scriber Cap & 2-Part Head Flashing) and a vermin proofing for Drained Cavity

Palliside can be installed Direct Fix (Direct to the frame) from 0-12 points on the Building Envelope Risk Matrix. Palliside can be installed over a Drained Cavity from 0-20 points. For all installations from 13-20 points, Palliside must be installed over a Drained Cavity.

When installing Palliside Direct to Frame, an absorbent Breather type Building Paper/Wrap must be used. As a result some synthetic Building Wraps cannot be used with Palliside. Please check that the correct type of Building Wrap is to be used.

Ensure that the correct Jamb Width allowance has been made for the Joinery. For Palliside Installed Direct Fix, the Building Code requires a 5mm off set (gap at base of joinery). This gap must be allowed for Direct Fix applications but is not compulsory when installing over a Drained Cavity.

Installing Palliside Weatherboards (Direct Fix)

The following steps provide a quick summary for installing Palliside. Please ensure you read the Palliside 'Technical Guide' and appropriate 'Installation Guide' before starting work. Copies can be downloaded below or sourced from Dynex Extrusions Ltd.

WARNING: Non-absorbent Synthetic building papers must not be used with Palliside as they are unsuitable for use with non-absorbent claddings such as steel, aluminium and PVC Palliside weatherboards for your home.

For best results ensure Windows are on site before installation commences.

Step 1. Install extruded accessory bases.

Fix accessory bases in place BEFORE fixing weatherboards and fitting joinery. Ensure the correct Corner options are used. Nail with Palliside nails at 300 mm centres. Use chalk line and level to ensure starter strips are straight, ensuring the bottom weatherboard will overlap the bottom plate by a minimum 50 mm. Leave a 5 mm gap for expansion between each length.

Step 2. Install weatherboards to Sill Height

Cut boards using standard tools. Allow 5 mm where weatherboards join for expansion meet the accessory bases or meet openings for joinery. Clip the bottom board into the starter strip and nail to each stud (maximum 600 mm centres) using Palliside nails. Do not use Gib clouts. Clip subsequent courses of weatherboard into place and nail in the same way, working from the base of the wall up. Clip corner Soakers in place as you go to ensure weatherboards are level. Cut weatherboard around opening to suit. Pack and fix weatherboard at a maximum 600mm centres.

Step 3. Installation around Joinery.

Ensure that opening has the correct flashing tapes installed. Install Sill Tray and Jamb Flashing base and apply sealant where these meet. Place Joinery into opening and pack and nail in place. Continue to install weatherboards to Window Head.

Step 4. Installation of Head Flashing.

Cut 2-Part Head Flashing allowing for an additional 20mm cover either side of opening. Place Base and cap against the flange of the aluminium and nail through base piece. Cover width with flashing tape before removing Head Flashing Cap.

Step 5. Installation to Soffit Line.

Continue the installation of the weatherboards to the soffit line. Ensure that weatherboards at soffit line are packed (if appropriate) and fixed in place at maximum 600mm centres.

Step 6. Finishing.

Clip extruded accessory caps (such as internal corner caps) into position. Clip moulded corner soakers into position. Run a bead of solvent cement down one side of the back of each moulded flat soaker and clip into position. Glue Window Scriber Caps into location on Jamb Flashing Base. Use solvent cement to fix moulded end plugs into position at the sides of Jamb Flashing Base and internal corner and trims.

TIPS. Some keys to good installation:

1. Read the latest versions of the Palliside Technical Guide and the appropriate Palliside Installation Guide. Determine the appropriate method of Installation (Direct Fix or Drained Cavity)
2. Ensure that the correct materials including windows are on site before commencing installation
3. Ensure that the correct type of Building Paper/wrap has been applied and the correct joinery width and window installation allowed for
4. Handle product with care
5. Plan ahead (Make up a Story-Rod)
6. Ensure Starter Strip is level and the correct corner base accessories have been installed (maximum 300mm centres). Ensure the correct accessories are installed at openings.
7. When nailing through the weatherboards, point the nails slightly down.
8. Take care to make sure boards are lapped correctly and are level before nailing
9. Pack out cut boards
10. Use the solvent cement with care and have a damp rag on hand to wipe off excess glue. Take care when cutting weatherboard at the Head Flashing
