4.1 Resene Construction Systems Flashings

3.1.1. General Notes

Comply with the Trade Specific penetration flashing guidelines. Carry out to the required standard of execution to ensure water does not penetrate.

Refer to Resene Construction Systems technical drawings for the specified system being installed.

3.1.2. Priming Flashings

All Resene Construction Systems Flashings must be primed. It is a requirement of Resene Construction Systems to use a solution of 50% Acrylbond, 50% Water and Rockcote MultiStop Bedding compound or Enduron AAC Panel Joint Compound. This is then brushed on to the flashings and left 24 hours so that it can adhere and cure.

3.1.3. Fixing flashings

Use 40mm galvanised clouts to temporarily fix flashings in place.

Adhering Flashings using low expansion adhesive foam

(Refer to Resene Construction Systems TradeSpec™ document 3.6 Low Expansion Adhesive Foams)

Adhering Flashings using non solvent based glues

(Refer to Resene Construction Systems TradeSpec™ document 3.5 Adhesives)

3.1.4. Rockcote/PSL Starter Strip Installation

Ground level

Must be installed directly after sheet installation at ground level to prevent contamination of the bottom edge. (Refer to Resene Construction Systems TradeSpec™ document 1.2.5 Ground Clearances)

Rockcote/PSL Window Head

Not applicable for Rockcote Edge Seal Head Flashing Installation (Refer to Resene Construction Systems TradeSpec™ document 3.11 Rockcote EdgeSeal Flashing installation)

Must be installed to the bottom edge of the substrate above the aluminium head flashing, leaving 10mm clearance from the aluminium head flashing. Must be trimmed and positioned to the fit accurately above the aluminium head flashing.

3.1.5. Rockcote/PSL Sill Flashings Installation

Not applicable for Rockcote Edge Seal Sill Flashing Installation (Refer to Resene Construction Systems TradeSpec™ document 3.11 Rockcote EdgeSeal Flashing installation)

Sill flashings must be one continuous length. If joinery exceeds flashing length, the joint must be under-flashed with Butyl based flashing tape to the underside of the flashing prior to adhesive foam application.

Sill flashings must extend 10mm(min) beyond the outside edge of the joinery to allow for Jamb flashing intersection.

Refer to Resene Construction Systems RenderSpec™ section 5 if Corner Soakers are required. If they are, refer to their installation procedures in Resene Construction Systems TradeSpec™ document 3.1.7 Rockcote Sill and Head Flashing Soaker

3.1.6. Rockcote/PSL Jamb Flashing Installation

Not applicable for Rockcote Edge Seal Jamb Flashing Installation (Refer to Resene Construction Systems TradeSpec™ document 3.11 Rockcote EdgeSeal Flashing installation)

Jamb flashings must be one continuous length. If joinery exceeds flashing length, the joint must be under-flashed with Butyl based flashing tape to the underside of the flashing prior to adhesive foam application.

Jamb flashing to sill flashing

Jamb flashings must be cut to the correct Sill flashing ‘slope’ to form a neat junction where they align to the Sill flashing. Jamb flashings must extend over the Sill flashing upstand

Allow 5mm clearance off the top face of the Sill flashing at the internal corner of flashing junction to allow for sealant bead.

Sealant must be applied between the Sill flashing upstand and the back face of the Jamb flashing.

Refer to Resene Construction Systems technical drawings for the specified system being installed.

Refer to Resene Construction Systems RenderSpec™ section 5 if Corner Soakers are required. If they are, refer to their installation procedures in Resene Construction Systems TradeSpec™ document 3.1.7 Rockcote Sill and Head Flashing Soaker

Jamb flashing to window head flashing

Jamb flashing must be trimmed to accommodate the aluminium head flashing, and Head flashing soaker.

Jamb flashing must be placed to the underside of the Head flashing soaker.

Refer to Resene Construction Systems technical drawings for the specified system being installed.

Refer to Resene Construction Systems RenderSpec™ section 5 if Sill or Head Flashing Soakers are required. If they are, refer to their installation procedures inResene Construction Systems TradeSpec™ document 3.1.7 Sill and Head Flashing Soaker

3.1.7. Sill and Head Flashing Soaker Installation

Refer to Resene Construction Systems technical drawings for the specified system being installed.

Rockcote/PSL Sill Flashing Soaker Installation

Soaker is trimmed to suit cladding depth, and inserted onto each end of the pre-cut Sill flashing prior to installation below joinery.

Rockcote/PSL Head Flashing Soaker Installation

Soaker is trimmed to suit cladding depth, and inserted onto each end of the Aluminium head flashing prior to installation of substrate, and any other cladding component.

3.1.8. Rockcote LiteRock Starter Strip

Ground level

Must be installed prior to substrate installation, to allow for accurate level and substrate installation. Installed by the main contractor.

(Refer to Resene Construction Systems TradeSpec™ document 1.2.5 Ground Clearances)

Window Head

Must be installed prior to substrate installation above the aluminium head flashing, leaving 10mm clearance from the aluminium head flashing. Must be trimmed and positioned to the fit accurately above the aluminium head flashing.

3.1.9. Rockcote Control Joints

Rockcote Vertical control joint installation

Where a vertical control joint intersects with starter strips, the starter strip must be cut to allow for substrate movement. Refer to Resene Construction Systems TradeSpec 1.4™ – Control Joints

10mm space between adjacent substrate must be allowed for the positioning of horizontal control joint.

Must be one continuous length. If cladding section exceeds flashing length, the joint must be under-flashed with Butyl based flashing tape to the underside of the flashing prior to installation.

(Refer to Resene Construction Systems TradeSpec™ document 1.4 Control Joints)

Rockcote Horizontal control joint installation

10mm space between adjacent substrate must be allowed for the positioning of horizontal control joint.

Must be one continuous length. If cladding section exceeds flashing length, or at an external or internal corner the joint must be under-flashed with EIFS butyl tape to the underside of the flashing prior to installation.

(Refer to Resene Construction Systems TradeSpec™ document 1.4 Control Joints)

Rockcote Horizontal control joint installation – Rigid backing board

35mm space between adjacent substrate must be allowed for the positioning of horizontal control joint.

Must be one continuous length. If cladding section exceeds flashing length, or at an external or internal corner the joint must be under-flashed with EIFS butyl tape to the underside of the flashing prior to installation.

(Refer to Resene Construction Systems TradeSpec™ document 1.4 Control Joints)

3.1.10. Dissimilar cladding junctions

Refer to Resene Construction Systems and adjacent cladding manufacturers technical drawings.
